2 Overview

2 Overview The WCDMA system is an interference-limited system, and the most important way to restrain system interference is power control. The power control is performed by the user equipment (UE) and universal terrestrial radio access network (UTRAN) to adjust and control the power of transmitting signals according to changes of the channel conditions and quality of received signals. The uplink and downlink power is minimized while ensuring quality of service (QoS).

2.1 Uplink and Downlink Power Control The main purpose of power control is to decrease interference to other UEs and to lower UE transmit power. 

In the uplink, a UE emitting too high power will cause unacceptable competing interference on the NodeB in comparison to signals coming from UEs at the cell edge. This is called near-far effect. To avoid near-far effect, uplink power control is required.



In the downlink, the system capacity is determined by the total code power. Therefore, it is necessary to keep the transmit power at the lowest possible level while still ensuring signal quality at the UE.

Power control is also used to compensate for shadow and fast fading as well as power drift. By using power control to compensate for power drift, soft handover performance in the downlink is improved. The downlink power balance (DPB) algorithm is introduced to reduce the power drift between links when the UE is in soft or softer handover.

2.2 Power Control Types Power control is classified into the following types: 

Open loop power control (WRFD-020501 Open Loop Power Control) At open loop power control, the initial transmit power is calculated. The UE estimates the power loss of signals on the propagation path by measuring the downlink channel signals and then calculates the initial transmit power of the uplink channel. This method is rather inaccurate and it is only applied at the beginning of a connection setup. Open loop power control is applied on physical channels such as PRACH and DPCH.



Closed loop power control At closed loop power control, the transmitter dynamically adjusts its transmit power according to the feedback from the receiver of the other side. Closed loop power control is further classified into the following types: − Inner

loop power control (WRFD-020504 Inner Loop Power Control)

Inner loop power control directly adjusts the transmit power of the transmitter by using power control commands. Inner loop power control is a fast power control method and can be performed 1500 times per second. − Outer

loop power control (WRFD-020503 Outer Loop Power Control)

The target SIR (hereafter referred to as SIRtarget) is dynamically adjusted according to the uplink BLER/BER/RBLER/NHR. Outer loop power control indirectly controls the transmit power of the transmitter. Power control is classified into the following types, depending on channel types: 

Common channel power control



DCH channel power control



HSDPA power control



HSUPA power control

2 Overview

2.3 Organization Chapters 3 to 6 describe power control, including open loop and closed loop power control, for common channels, DCH channels, HSDPA channels, and HSUPA channels, respectively. HS-PDSCH power is configured by means of HSDPA power resource management and therefore this document does not describe the HS-PDSCH channel. Chapter 7 describes the enhanced functions and features related to power control. You need to learn about the basic features when reading chapter 7.

3 Common Channel Power Control

3 Common Channel Power Control Common channels consist of the PRACH in the uplink and the P-CPICH, P-SCH, S-SCH, P-CCPCH, S-CCPCH, AICH, and PICH in the downlink. Only open loop power control is used on these common channels.

3.1 Power Control on Uplink Common Channels The PRACH is the only common channel on which the uplink open loop power control is applied.

The process of power control on the PRACH is as follows: 1. The UE transmits the first preamble to the NodeB to start an access process. The power of the first preamble is computed with the following formula: Preamble_Initial_Power = PCPICHPower- CPICH_RSCP + UL interference + Constantvalue where − PCPICHPower − CPICH_RSCP

defines the P-CPICH transmit power in a cell.

is the received signal code power of the P-CPICH.

− UL interference

indicates the uplink RTWP.

− Constantvalue

for calculating the initial transmit power compensates for the RACH processing gain. It is broadcast in SIB 5.

2. If no acquisition indicator is received by the UE, a preamble ramping procedure starts. To avoid collisions, the UE must wait for a time between two consecutive preambles. The waiting time is configured by AICHTxTiming on the RNC. The power of preamble is increased for each retransmission by a power ramp step configured by PowerRampStep on the RNC. 3. If the UE receives a negative acquisition indicator on the AICH, the UE waits for a certain period and then initiates the random access procedure again. This period is called the back-off delay. The parameters NB01min and NB01max define the lower and upper limits of the back-off delay. If the value of NB01min is equal to that of NB01max, it means that the retransmission period of the preamble part is fixed. A preamble ramping procedure consists of several preamble ramping cycles, which cannot exceed Mmax. In each cycle, the UE retransmits the preamble until the UE receives the acquisition indicator or the number of retransmissions has reached PreambleRetransMax.



3-1



4. If the UE receives a positive acquisition indicator, the UE exits the random access procedure, sets the power for the message part, and transmits the message part after a period configured by AICHTxTiming. The message part consists of two parts: The control part and the data part. The power of the control part is the same as the power of the last transmitted preamble plus a value defined by PowerOffsetPpm. PowerOffsetPpm must be set for each instance of PRACH TFC. It is recommended that the value of PowerOffsetPpm be set to -3 dB corresponding to the TFC for signaling transmission and be set to -2 dB corresponding to the TFC for service transmission. If the value of PowerOffsetPpm is set too small, it is likely that the signaling or the service data carried over the RACH cannot be correctly received, which affects the uplink coverage. If the value is set too large, the uplink interference is increased, and the uplink capacity is affected. The power of the data part is calculated with the following formula: Pdata = Pcontrol x (βd/βc)2 where − Pcontrol

is the power for the control part.

− βd

is the power gain factor for the data part. The value is defined by GainFactorBetaD.

− βc

is the power gain factor for the control part. The value is defined by GainFactorBetaC.

The transmit power on the PRACH cannot be larger than the maximum allowed uplink transmit power. This maximum power is limited by the following parameters configured on the RNC: 

MaxUlTxPowerforConv (conversational)



MaxUlTxPowerforBac (background)



MaxUlTxPowerforInt (interactive)



MaxUlTxPowerforStr (streaming)



MaxAllowedUlTxPower

Larger values increase coverage of corresponding service type. If the values of these parameters are too large, there is a risk the uplink and downlink coverage of related service will become unbalanced. If the values of these parameters are too small, there is a risk the uplink coverage will become smaller than the downlink coverage of the service. If there is no special requirement, use the default values.

3.2 Power Control on Downlink Common Channels This section describes how much power is allocated to downlink common channels. The downlink common channels are as follows: 

Primary Common Pilot Channel (P-CPICH)



Primary Synchronization Channel (P-SCH)



Secondary Synchronization Channel (S-SCH)



Primary Common Control Physical Channel (P-CCPCH)



Secondary Common Control Physical Channel (S-CCPCH)



Acquisition Indicator Channel (AICH)



Paging Indicator Channel (PICH)

The power of downlink common channels is fixed and can be configured on the RNC by the parameters listed in the following table.



3-2



Parameter

Description

PCPICHPower

The P-CPICH power is specified by PCPICHPower as an absolute value in dBm. The transmit power of any other channel is an offset from the P-CPICH power. P-CPICH transmit power is related to the downlink coverage defined during network planning. If the value of this parameter is too small, it will directly influence the downlink pilot coverage range. If it is too large, the downlink interference will increase, and the transmit power that can be distributed to the services will be reduced, which will affect the downlink capacity. In addition, the configuration of this parameter has influence on the distribution of handover areas.

PSCHPower SSCHPower

The values of PSCHPower and SSCHPower must not be too large. The parameter values can be adjusted based on the measurement in the actual environment, so that the transmit power of the synchronization channels satisfies the UE reception and demodulation requirements. The transmit power should be enough to ensure that a UE can implement fast synchronization in most areas of the cell edge. Neither the P-SCH nor the S-SCH comes through channel code spectrum spreading, so they produce more serious interference than other channels, especially for near-end UEs.

BCHPower

BCHPower is set based on the measurement in the actual environment. If the value of this parameter is too small, the UEs at the cell edge will fail to receive the system information correctly, and the downlink coverage will be influenced. If the value is too large, other channels are affected and the cell capacity will be reduced.

MaxFachPower

Set the value of MaxFachPower to a value that is enough to ensure the target block error rate (BLER). If the value of this parameter is too small, the UEs at the cell edge will fail to receive correctly the services and signaling carried over the FACH, which results in influence on the downlink coverage. If it is too large, other channels will be affected and the cell capacity will be reduced. In addition, when the downlink power is overloaded, MaxFachPower may be changed. For the related function, see Load Control Feature Parameter Description.

PCHPower

If the value of this parameter is too small, the UEs at the cell edge will fail to receive paging messages correctly, which will influence cell coverage. If it is too large, other channels will be affected and the cell capacity will be reduced.

AICHPowerOffset

Ensure that all UEs at the cell edge can receive the access indication. To avoid wasting power, the transmit power should not be too large.

PICHPowerOffset

If the value of this parameter is too small, the UEs at the cell edge will fail to receive paging indicators correctly, which will affect the downlink coverage. If it is too large, other channels will be affected and the cell capacity will be reduced.

4 DCH Channel Power Control

4 DCH Channel Power Control 4.1 Overview DCH channels consist of the DPCH in the uplink and the DPCH and the F-DPCH in the downlink. Uplink DPCHs consist of the uplink DPCCH and the uplink DPDCH, and they use different OVSF codes. Downlink DPCHs consist of the downlink DPCCH and DPDCH, and they use the same OVSF code by time division multiplexing. DCH channel power control methods are open loop power control, inner loop power control, and outer loop power control. 

Open loop power control provides initial power of channels.



Inner loop power control adjusts channel power by comparing the SIR of the received signal with the SIRtarget.



Outer loop power control adjusts the SIRtarget by comparing the BLER target and the BLER of the received DCH.

Figure 4-1 shows an example of uplink DCH channel power control. Figure 4-1 Uplink DCH channel power control

4.2 Open Loop Power Control Based on the measurement of received downlink signal power, open loop power control attempts to make a coarse estimation of the path loss and based on this provide initial power for the UE and NodeB.

4.2.1 Uplink Open Loop Power Control on DPCH The uplink open loop power control on the DPCH is to calculate the initial power of the first DPCCH. The initial power of the DPDCH is calculated based on the power offset between the DPCCH and the DPDCH.

Initial Power of Uplink DPCCH The UE calculates the initial power with the following formula: DPCCH_Initial_Power = DPCCH_Power_Offset - CPICH_RSCP where 

DPCCH_Initial_Power is the initial power.



DPCCH_Power_Offset is provided by the RNC and sent to the UE.



4-1

WCDMA RAN Power Control 


CPICH_RSCP is the received signal code power of the P-CPICH.

The DPCCH_Power_Offset is calculated by the RNC with the following formula: DPCCH_Power_Offset = PCPICHPower + Uplink interference + DefaultConstantValue where 

DPCCH_Power_Offset is the power offset of the DPCCH.



PCPICHPower defines the P-CPICH transmit power in a cell. This value is broadcast in SIB 5.



Uplink interference is the uplink RTWP measured by the NodeB and sent to the UE through the SIB 7.



DefaultConstantValue is used to set the power offset of the DPCCH to a conservative level to avoid excessive uplink interference.

Power of Uplink DPDCH The power of the uplink DPDCH is set as a power offset (βd/βc) reference to the uplink DPCCH. The uplink DPCCH and DPDCHs are transmitted through different channel codes. To meet a given QoS requirement on the transport channels, different TFCs use different power offsets. The RNC has a set of reference values (βc,ref and βd,ref) that are stored for each predefined radio access bearer (RAB) or signaling radio bearer (SRB). βc,ref and βd,ref can be configured by BETAC and BETAD on the RNC. The RNC calculates a new power offset for each TFC based on the reference values dynamically and sends the power offset to the UE. In an RAB combination, all the radio bearers use the reference values of the bearer who has the maximum bit rate. For example, for the combination of 3.4 kbit/s SRB service, 384 kbit/s background service, and 12.2 kbit/s AMR service, the reference power offset values applied are those belonging to the 384 kbit/s background radio bearer.

Preamble of Uplink DPCCH Power Control An uplink DPCCH Power Control (PC) preamble is a segment of uplink DPCCH transmission that is sent before the start of the uplink DPDCH transmission. The PC preamble is used to ensure that the inner loop power control has converged before the transmission of DPDCH data starts. The RNC transfers the PC preamble parameter (number of DPCCH preamble timeslots) to the UE by using RRC signaling. The UE does not send any data on SRBs during the frames of preambles and frames indicated in the SRB delay IE. Depending on application scenarios, different values for the length of PC preamble and SRB delay are used as follows: 

In the case of RRC connection establishment, the length of PC preamble is seven frames and SRB delay is zero frames.



In the case of hard handover, the length of PC preamble is seven frames and SRB delay is also seven frames.

When the DPCCH PC preamble has been transmitted and the SRB delay passed, the UE starts transmitting data on the DPDCH at initial transmit power.

4.2.2 Downlink Open Loop Power Control on DPCH Downlink open loop power control on the DPCH is to calculate the DPDCH power based on the measurement results in the RACH IE from the UE. The DPCCH power is set as the power offset reference to the DPDCH.



4-2



Initial Power of Downlink DPDCH The RNC uses the P-CPICH power, the traffic rate requested by the UE, measured Ec/N0 on CPICH and the downlink transmitted carrier power as input in calculating the initial power of downlink DPDCH. During soft handover, the initial power of the new radio link decreases by a power offset of 15 dB to save downlink power. The decrease is valid only when PC_DOWNLINK_POWER_BALANCE_SWITCH under the PcSwitch parameter is selected. The power of the downlink DPDCH is limited for each radio link by RlMaxDlPwr and RlMinDlPwr. The values for RlMaxDlPwr and RlMinDlPwr are different for different data rates of RABs. 

If the UE establishes only one service on the DCH, RlMaxDlPwr and RlMinDlPwr for the DPDCH are determined by the values for RlMaxDlPwr and RlMinDlPwr for this service.



If the UE establishes multiple services on the DCH, RlMaxDlPwr and RlMinDlPwr for the DPDCH are determined together by the values for RlMaxDlPwr and RlMinDlPwr, and rate matching gains and spreading gains of each service. This ensures that the maximum and minimum downlink power for the DPDCH meets the power requirements of each service.



If the WRFD-150235 DPCH Maximum Power Restriction feature is activated, the NodeB will adjust the value for RlMaxDlPwr for the downlink HSDPA A-DPCH. For details about this feature, see section 0"For descriptions of the power load state specified by the LoadStateForPilotPwrAdj parameter, see related descriptions in section 3.1 "Load-related Measurement Quantities" of Load Control Feature Parameter Description.



." A-DPCH is short for associated dedicated physical channel.

Power of Downlink DPCCH The downlink DPCCH consists of three fields: TFCI, TPC, and pilot. Their power is set as the offset reference to the power of the downlink DPDCHs. The downlink power on the DPCCH and its associated DPDCHs is simultaneously regulated. Therefore, power control adjusts the power of the DPCCH and DPDCHs with the same step, and the power offset between the DPCCH and the DPDCH keeps constant. Power offsets between the DPCCH and the DPDCH in the downlink are identical for all TFCs in the TFCS, whereas in the uplink the power offsets are TFC-dependent. The power offsets of TFCI and TPC of the DPCCH relative to the power of DPDCHs are fixed at 0 dB and 3 dB, respectively. 

If the WRFD-150230 DPCH Pilot Power Adjustment feature is not activated, the pilot-field power offset has a fixed value of 3 dB.



If this feature is activated, see section 7.1.1 "DPCH Pilot Power Adjustment" for the setting of the pilot-field power offset.

4.2.3 Downlink Open Loop Power Control on F-DPCH Open loop power control on the F-DPCH uses the P-CPICH power, the downlink transmitted carrier power, measured Ec/N0 on CPICH and the Ec/N0 required for satisfying the TPC symbol error rate of the F-DPCH as input in calculating the initial power of downlink F-DPCH. During soft handover, the initial power of the new radio link decreases by a power offset of 15 dB to save downlink power. The decrease is valid only when PC_DOWNLINK_POWER_BALANCE_SWITCH under the PcSwitch parameter is selected. The power of the downlink F-DPCH is limited by the maximum power (PCPICHPower + FdpchMaxRefPwr + FdpchPO2) and minimum power (PCPICHPower + FdpchMinRefPwr + FdpchPO2).

4.3 Inner Loop Power Control Inner loop power control is also called fast power control. The UE or NodeB controls the transmit power according to the power control information returned from the receiver, to compensate for the fading of radio links. Inner loop power control consists of uplink inner loop power control and downlink inner loop power control, which work independently. The inner loop power control may work in normal mode or compressed mode.

4.3.1 Uplink Inner Loop Power Control in Normal Mode on DPCH Uplink inner loop power control is used on the DPCCH. The power of the relative DPDCHs is configured as the power offset (βd/βc) reference to the power of the DPCCH. For details of the DPDCH, see section "Uplink Open Loop Power Control on DPCH." The procedure of inner loop power control on the uplink DPCCH is as follows: 1. The RNC sends an SIRtarget, denoted as SIRtarget, to the cells in the active set. 2. Each cell in the active set estimates the SIR, denoted as SIRest, at each timeslot and compares it with the SIRtarget. 3. The cell in the active set sends a TPC command to the UE based on the comparison result. − If

SIRest is larger than SIRtarget, the cell in the active set sends a TPC command 0 to the UE.

− If

SIRest is smaller than or equal to SIRtarget, the cell in the active set sends a TPC command 1 to the UE.

4. The UE adjusts the transmit power according to the TPC command. There are two types of inner loop power control algorithms: PCA1 and PCA2. The UE uses the algorithms to translate the received TPC commands. The RNC can select the algorithm based on the configuration of PwrCtrlAlg and inform the UE of the selected algorithm. When using the PCA1, the UE adjusts the uplink transmit power for every timeslot. When using the PCA2, the UE adjusts the uplink transmit power in a 5-timeslot cycle. The power increment/reduction is calculated with the following formula: ΔDPCCH = ΔTPC x TPC_cmd where 

ΔDPCCH is power increment/reduction on the DPCCH.



TPC_cmd is calculated by the PCA1 or PCA2 according to the TPC command received by the UE.

ΔTPC is the step of power control. For PCA1, it is determined by UlTpcStepSize. For PCA2, the step is fixed at 1 dB.

4.3.2 Uplink Inner Loop Power Control in Compressed Mode on DPCH The power control method in compressed mode is similar to that in normal mode, and it aims at restoring the SIR to the SIRtarget as quickly as possible after each transmission gap, to avoid block errors during and after the compressed frames. To achieve this restoration, the power control increases the power and the SIRtarget used in the UE.



4-4



Adjusting SIRtarget During the transmission gap, the cells in the active set do not estimate the SIR and generate TPC commands. The SIRtarget used in compressed mode will be increased to compensate for the interruption due to transmission gaps. The compressed and non-compressed frames in uplink DPCCH may have a different number of pilots per slot. In the compressed frame, the number of pilots per slot is decreased. So the SIRtarget used in compressed mode need take the change of the number of pilot bits into consideration. The compensated SIRtarget for the change of the number of pilot bits is calculated by the following formula: ΔSIRPILOT = 10Log10 (Npilot,N/Npilot,curr_frame) where 

ΔSIRPILOT is the compensated SIRtarget.



Npilot,curr_frame is the number of pilot bits per timeslot in the current uplink frame.



Npilot,N is the number of pilot bits per timeslot in a normal uplink frame without a transmission gap.

Adjusting Power The UE uses ΔDPCCH to adjust the UE uplink DPCCH transmit power on each timeslot in compressed mode. ΔDPCCH = ΔTPC x TPC_cmd + ΔPILOT where 

ΔDPCCH is power increment/reduction.



ΔTPC is the step of power control.



TPC_cmd is calculated from TPCs by the PCA algorithm



ΔPILOT = 10Log10 (Npilot,prev/Npilot,curr) where − Npilot,prev

is the number of pilot bits in the previous transmitted timeslot.

− Npilot,curr

is the number of pilot bits in the current timeslot.

4.3.3 Downlink Inner Loop Power Control in Normal Mode on DPCH/F-DPCH The power of the downlink DPDCH is set as the offset reference to the power of the DPCCH. Therefore, downlink inner loop power control regulates the power of the DPCCH and DPDCH together. For details of the offset, see section 4.2.2 "Downlink Open Loop Power Control on DPCH." The procedure of downlink inner loop power control is as follows: 1. The UE obtains the SIRtarget from the L3 (Layer 3), which is denoted as SIRtarget. The SIRtarget is determined by outer loop power control. For a downlink F-DPCH, the SIRtarget is set automatically by the UE based on the error rate target of TPC command sent from the UTRAN. 2. The UE estimates the downlink SIR from the pilot symbols of the downlink DPCH, expressed as SIRest, and compares the SIRest with the SIRtarget. 3. Based on the comparison result, the UE transmits a TPC command to the NodeB. − If

SIRest is larger than SIRtarget, the UE sends a TPC command 0 to the NodeB.

− If

SIRest is less than SIRtarget, the UE sends a TPC command 1 to the NodeB.

The UE sends a TPC command to the NodeB periodically; the interval is decided by DpcMode. When DpcMode is set to SINGLE_TPC, the UE sends a TPC command for every timeslot; when DpcMode is set to TPC_TRIPLET_IN_SOFT, the UE sends a TPC command in a 3-timeslot cycle; when DpcMode is set to TPC_AUTO_ADJUST, the interval can be adjusted automatically by sending the ACTIVE SET UPDATE message to the UE. 4. The UTRAN estimates the transmitted TPC and updates the DPCH power every timeslot. In the case of softer handover, the NodeB uses the maximum ratio combining (MRC) algorithm to derive a combined TPC command. The UTRAN calculates the power adjustment with the following formula: P(k) = P(k-1) + PTPC(k) + Pbal(k) where 

P(k) is the new downlink power.



P(k-1) is the current downlink power.



PTPC(k) is the kth power adjustment due to the received TPC of inner loop power control.



Pbal(k) is a correction due to downlink power balance. In the scenario of a single radio link, Pbal is equal to 0. For details, see chapter 4.3.5 "Downlink Power Balance."

The PTPC(k) is calculated as follows: If PC_INNER_LOOP_LMTED_PWR_INC_SWITCH under the PcSwitch parameter is set to OFF, then the following formula is used:



If the TPC is equal to 1, the power is increased by ΔTPC.



If the TPC is equal to 0, the power decreases by ΔTPC.

ΔTPC is determined by FddTpcDlStepSize. TPCest is the estimated TPC. If PC_INNER_LOOP_LMTED_PWR_INC_SWITCH under the PcSwitch parameter is set to ON, then the following formula is used:



4-6





If the TPC is equal to 1, and the sum of Δsum(k) and ΔTPC is smaller than Power_Raise_Limit, the power is increased by ΔTPC.



If the TPC is equal to 1, and the sum of Δsum(k) and ΔTPC is larger than or equal to Power_Raise_Limit, the power is not adjusted.



If the TPC is equal to 0, the power decreases by ΔTPC. where − Δsum(k)

is the sum of inner loop power increment/reduction within 20 timeslots.

− Power_Raise_Limit

is fixed at 10 dB.

4.3.4 Downlink Inner Loop Power Control in Compressed Mode on DPCH/F-DPCH The power control method in compressed mode is similar to that in normal mode, and it aims at restoring the SIR to the SIRtarget as quickly as possible after each transmission gap, to avoid block errors during and after the compressed frames. To achieve this restoration, the power control increases the power and the SIRtarget used in the UE.

Adjusting SIRtarget The calculation method of the downlink SIRtarget in compressed mode is similar with that of uplink. The RNC uses compression method and the position of transmission timeslot in the current frame as input in calculating SIRtarget in the compressed mode.

Adjusting Power The power of the DPCCH and DPDCH in the first timeslot after the transmission gap should be set to the same value as that in the timeslot just before the transmission gap. In compressed mode, the UTRAN estimates the power with the following formula: P(k) = P(k-1) + PTPC(k) + PSIR(k) + Pbal(k) where 

P(k) is the new power.



P(k-1) is the current downlink power.



PTPC(k) is the kth power adjustment due to the received TPC of inner loop power control.



PSIR(k) is the kth power adjustment due to the downlink SIRtarget variation. For the F-DPCH, the power offset PSIR(k) = 0.



Pbal(k) is a correction due to downlink power balance.

Table 4-2 provides the comparison between downlink inner loop power control in normal and compressed modes.

4.3.5 Downlink Power Balance This chapter describes the feature WRFD-020502 Downlink Power Balance. Downlink power balance is used to reduce power drift between downlink radio links in macro diversity operation. During soft handover, the uplink TPC command is demodulated in each radio link set (RLS). Because of demodulation errors, the downlink transmit power of each branch drifts separately, which causes loss to the macro diversity gain. During softer handover, the power among all branches may drift because of initial power difference. The DPB algorithm is introduced to reduce the power drift between links when the UE is in soft or softer handover. Figure 4-2 Downlink power balance

The implementation of the DPB algorithm is as follows: 1. Reporting the transmitted code power According to measurement control from the RNC, the NodeB periodically reports the transmitted code power of each radio link in soft or softer handover to the RNC.



4-8



2. Evaluating the power difference For UEs in softer handover, the RNC evaluates the power difference of the radio links and decides whether to start or stop downlink power balance. For UEs in soft handover, downlink power balance is always active. 3. Calculating the UE downlink reference power (Pref) The RNC calculates the downlink reference power Pref and transmits the Pref to the NodeB through the DOWNLINK POWER CONTROL REQUEST message. Pref = 0.5 x (Pmax - Pcpich, max) +0.5 x (Pmin - Pcpich, min) where − Pref

is the downlink reference power.

− Pmax

is the maximum downlink transmitted code power of all the UE radio links.

− Pcpich, max

is the P-CPICH power value of the cell that has the highest downlink transmitted code power among all the UE radio links.

− Pmin

is the minimum downlink transmitted code power of all the UE radio links.

− Pcpich, min

is the P-CPICH power value of the cell that has the lowest downlink transmitted code power among all the UE radio links.

4. The NodeB calculates and adjusts the transmitted code power of each radio link. In a DPB adjustment period of two frames, the total power correction is calculated with the following formula: Pbal=(1-r) x (Pref + PP-CPICH - Pinit) where − Pbal −r

is the total power correction.

is fixed at 0.

− Pref

is the reference power that is calculated in the previous step.

− PP-CPICH − Pinit

is the P-CPICH transmit power in a cell, which is defined by PCPICHPower.

is the transmit power of a radio link before adjustment.

Pbal determines the total power to be adjusted in a DPB adjustment cycle. In a 4-timeslot cycle, the total power to be adjusted cannot exceed 1 dB, and the adjustment step of each timeslot is fixed at 0.25 dB. The transmitted code power is calculated with the following formula: P(i) = P(i-1) + PTPC(i) + Pbal(i) where 

P(i) is the transmitted code power of timeslot i.



P(i-1) is the transmitted code power of timeslot (i-1).



PTPC is the result of inner loop power control.



Pbal is a corrective term introduced by downlink power balance.

4.4 Outer Loop Power Control There are the DCH outer loop power control algorithm and E-DCH outer loop power control algorithm depending on where RBs are carried. This section describes the DCH outer loop power control algorithm based on the BLER or bit error rate (BER). For the E-DCH outer loop power control algorithm based on the NHR or RBLER, see section 6.3 "E-DCH Outer Loop Power Control."



4-9



Outer loop power control is a part of the closed loop power control, used to maintain the communication quality at the level required by the service bearer through adjustment of the SIRtarget. This power control acts on each DCH belonging to the same RRC connection. The SIRtarget needs to be adjusted when the UE speed or the multi-path propagation environment changes, so that the communication quality can remain unaffected. The adjustment of the SIRtarget is based on the BLER or BER. When PC_OLPC_SWITCH under the PcSwitch parameter is set to ON, there are two cases: 

If there is data transmission in the uplink, the SRNC adjusts the SIRtarget based on the BLER.



If there is no data transmission in the uplink, the SRNC adjusts the SIRtarget based on the BER.

When PC_OLPC_SWITCH under the PcSwitch parameter is set to OFF, the SIRtarget is fixed and the uplink outer loop power control for all UEs is deactivated. Downlink outer loop power control is implemented by the UE. Therefore, downlink outer loop power control is determined by the UE manufacturer.

4.4.1 Uplink Outer Loop Power Control Based on BLER The uplink quality is observed after macro diversity selection combining in the RNC. Therefore, uplink outer loop power control is performed in the SRNC. Figure 4-3 Uplink outer loop power control

The SRNC compares the received block error ratio (BLER) with the BLER target. If the received BLER is larger than the BLER target, the SRNC increases the SIRtarget. Otherwise, the SRNC decreases the SIRtarget. The SIRtarget is calculated in the following formula: SIRtar(n) = MAX {[SIRtar(n-1) + (BLERmeas((n-1),1) – BLERtar(1))/BLERtar(1) x Step(1)], [SIRtar(n-1) + (BLERmeas((n-1),2) – BLERtar(2))/ BLERtar(2) x Step(2)]...[SIRtar(n-1) + (BLERmeas((n-1),i) – BLERtar(i))/BLERtar(i) x Step(i)]} where 

MAX is the maximum value of the SIRtarget in the total i transport channels in the nth adjustment period.



i is the ith transport channel and is from 1 to actual max number of the transport channels.



n is the nth adjustment period.



SIRtar(n) is the SIRtarget used in the nth adjustment period which can be defined by the SirAdjustPeriod parameter.



BLERmeas(n,i) is the instantaneous BLER measured for the ith transport channel in the nth adjustment period. The BLERmeas(n,i) is calculated with the following formula: BLERmeans(n,i) = TerrTb(n,i)/Tb(n,i)



4-10



where − Tb(n,i)

is the number of all blocks received from the ith transport channel in the nth adjustment

period. − TerrTb(n,i)

is the number of error blocks indicated by the cyclic redundancy check indicator (CRCI) in the Tb(n,i) that is received from the ith transport channel.



BLERtar(i) is the BLERtarget of the ith transport channel, which could be defined by the BLERQuality parameter.



Step(i) is the adjustment step of the ith transport channel, which could be defined by the SirAdjustStep parameter.

SIRtarget is adjusted per steps. In an outer loop power control adjustment period (SirAdjustPeriod), the maximum increase/decrease must not exceed a specified value (MaxSirStepUp/MaxSirStepDn), and SIRtarget must not exceed the upper threshold (MaxSirtarget) and lower threshold (MinSirtarget). The ΔSIRtar limitation is calculated with the following formula: ΔSIRtar = SIRtar(n+1) – SIRtar(n) 

If (ΔSIRtar > 0) and (ΔSIRtar > MaxSirStepUp), then SIRtar(n+1) = SIRtar(n) + MaxSirStepUp.



If (ΔSIRtar < 0) and (ABS(ΔSIRtar) > MaxSirStepDn), then SIRtar(n+1) = SIRtar(n) – MaxSirStepDn.

SirAdjustPeriod specifies the adjustment period of outer loop power control. Outer loop power control period works against changes in radio environment. A faster changing radio environment leads to a shorter outer loop power control adjustment period, whereas a slower changing environment makes the period longer. In case of multi-service: 

The maximum value of the SIRtarget among multiple services is used for the SIRtarget adjustment.



If one of the services requires increase in the SIRtarget, the reconfigured SIRtarget cannot exceed that maximum value.



The maximum value can be decreased only when all the services require decrease in the SIRtarget.

After adjusting the SIRtarget, the SRNC sends the new SIRtarget through Frame Protocol (FP) frames to all NodeBs under the SRNC for uplink inner loop power control. The initial SIRtarget value is service-dependent and is provided by the RNC to the NodeB. For different traffic classes, the adjustment step, maximum increase, maximum decrease of SIR target vary. Therefore, such variables are configured according to the traffic class. Table 4-3 lists recommended parameter configurations of typical services.

4.4.2 Uplink Outer Loop Power Control Based on BER Outer loop power control based on the BER is similar to the outer loop power control based on the BLER, but the BER is used as the control object. When the UE is in discontinuous transmission (DTX) mode, the RNC cannot receive data or update the BLER. Therefore, the BER is used to solve this problem. In an optimal condition, the BER target is the average BER after filtering within the adjustment period. The BER target is obtained before the DTX period starts during the outer loop power control period. During soft handover, the BER target is the minimum value among all the links. When the BLER is a constant, the BER on the DPCCH can vary within a limited range. The BERtarget is calculated in the following formula: F(n)=(1-a)F(n-1)+a*M(n) where 

F(n) is the average BER value after filtering.



4-12





a is the filter coefficient which can be set through the DtxBerTarFilterCoef or NonDtxBerTarFilterCoef parameter.



F(n–1) is the last average BER value after filtering, that is, the last filtering value.



M(n) is the current BER value.

During the DTX, the MAC measures the BER on the DPCCH, and the RNC compares it with the BER target. If the measured BER is smaller than the BER target, outer loop power control decreases the SIRtarget. Otherwise, outer loop power control increases the SIRtarget.

4.4.3 Downlink Outer Loop Power Control Downlink outer loop power control is implemented by the UE. Therefore, this algorithm is UE manufacturer specific. The information signaled to the UE by the RNC is a quality target for each radio bearer, expressed as a BLER target. Then, depending on the manufacturer-specific outer loop power control algorithm, an initial SIRtarget value can be deduced from this BLER value.

5 HSDPA Power Control

5 HSDPA Power Control This chapter describes the feature WRFD-01061004 HSDPA Power Control. Physical channels introduced by HSDPA are the HS-DPCCH in the uplink and the HS-SCCH and HS-PDSCH in the downlink. In the following situation, the power of the HS-PDSCH is dynamically allocated by TFRC and does not require the function of power control. 

The UE is in the CELL_DCH state.



The UE is in the enhanced CELL_FACH state and the HS-PDSCH carries the DTCH, DCCH or CCCH.

For detail information about TFRC, see HSDPA Feature Parameter Description. When the UE is in the enhanced CELL_FACH state and the HS-PDSCH carries the BCCH, the power of the HS-PDSCH is determined by the offset relative to the P-CPICH power. The offset is specified by BcchHspdschPower. When the UE is in the enhanced CELL_PCH or enhanced URA_PCH state, the power of the HS-PDSCH is determined by the offset relative to the P-CPICH power. The offset is specified by EPCHHSPDSCHPower. This section mainly introduces the HS-DPCCH power control and HS-SCCH power control.

5.1 Power Control on HS-DPCCH Overview The power of the HS-DPCCH is set by several power offsets between the HS-DPCCH and the associated uplink DPCCH. The power offsets consist of the ACK power offset, NACK power offset, and CQI power offset, as shown in Figure 5-1. The power offsets are set at each HS-DPCCH TTI. Figure 5-1 Power Control on HS-DPCCH



5-1



The HS-DPCCH transmit power is calculated with the following formula: PHS-DPCCH = PUL DPCCH x 10ΔHS-DPCCH/10 where 

PUL DPCCH is the transmit power of the associated uplink DPCCH.



ΔHS-DPCCH refers to the power offset of ACK, NACK, or CQI, that is, the power difference between the ACK/NACK/CQI and the uplink DPCCH.

The power offsets of ACK and NACK are related to the ACK/NACK repetition factor and HS-DPCCH preamble transmission indication. The power offset of CQI is related to the CQI repetition factor and CQI repetition period. A preamble and a postamble are transmitted before and after the NACK/ACK feedback respectively to improve the ACK/NACK decoding reliability. The transmit power of the first timeslot of the HS-DPCCH ACK/NACK can decrease to reduce the interference in the uplink.

ACK/NACK/CQI Power Offset The power offset is related to the number of RLSs and the repetition factor. DPCCHs have macro diversity gains, but the HS-DPCCH does not have. Therefore, the more links a UE in the soft handover state has, the larger the power offset should be set. The larger the repetition factor is, the smaller the power offset should be set. RNC automatically set ACK/NACK power offset and CQI power offset according to the UE capability and the number of RLSs in the active set. When the UE is in the single-RLS state, CQI power offset from UL DPCCH is specified by CQIPO. When the UE is in the multi-RLS state, CQI power offset from UL DPCCH is specified by CQIPOforSHO.

Repetition Factors Repetition factors of ACK/NACK and CQI are signaled to the UE and NodeB from the RNC. When the UE is in the single-RLS state, repetition factors of CQI are specified by CQIReF. When the UE is in the multi-RLS state, repetition factors of CQI are specified by CQIFbCkforSHO. The UE does not attempt to receive or decode transport blocks from the HS-DSCH sub-frames during the UE ACK or NACK retransmission.

CQI Feedback Cycle The CQI feedback cycle is signaled to the UE and NodeB from the RNC. When the UE is in the single-RLS state, duration of a CQI feedback cycle is specified by CQIFbCk. In each CQI feedback cycle, the UE retransmits CQI for N times repeatedly, where N represents the value of CQI repetition factor and is specified by CQIReF. The value of CQIFbCk is 0 that indicates no CQI information sent from the UE. When the UE is in the multi-RLS state, duration of a CQI feedback cycle is specified by CQIFbCkforSHO. When the UE is in the multi-RLS state, in each CQI feedback cycle, the UE retransmits CQI for N times repeatedly, where N represents the value of CQI repetition factor in the multi-RLS state and is specified by CQIReFforSHO. Value 0 of CQIFbCkforSHO indicates that no CQI information sent from the UE. For conversational services, the period of sending the CQI feedback is specified by CQIFBckforConver. For non-conversational services in MIMO mode without DC-HSDPA, especially the BE services and streaming services, the period of sending the CQI feedback is specified by CQIFBckforMimo. For non-conversational services in MIMO+DC-HSDPA mode, especially the BE services and streaming services, the period of sending the CQI feedback is specified by CQIFBckforDcMimo.

5.2 Power Control on HS-SCCH 5.2.1 Power Control on HS-SCCH in CELL_DCH The power control method for the HS-SCCH in CELL_DCH can be fixed (fixed transmit power control) or CQI-based (dynamic transmit power control). The method is specified by HSSCCHPWRCMINDCH. 

Fixed transmit power control: The power of the HS-SCCH is determined by the offset relative to the P-CPICH power. The offset is specified by SCCHPWR. The transmit power of the HS-SCCH is fixed without consideration of the channel quality but with consideration of the receive quality of UEs at the cell edge.



Dynamic transmit power control based on CQI: The NodeB dynamically adjusts the transmit power of the HS-SCCH based on the following information to improve the resource usage in the downlink. − CQI

reported by the UE

− DTX

detected by the NodeB

− Target

FER of the HS-SCCH, which can be set by HSSCCHFERTRGTINDCH on the NodeB

5.2.2 Power Control on HS-SCCH in Enhanced CELL_FACH When the UE is in the enhanced CELL_FACH state, its data and control information can be transmitted through the HS-PDSCH and HS-SCCH. The UE in the enhanced CELL_FACH state has no dedicated connection with the physical layer of the NodeB, and the UE does not quickly report the CQI, ACK, or NACK to the NodeB. Therefore, the function for HS-SCCH power control needs to be modified. 

When the UE is in the enhanced CELL_FACH state and the HS-PDSCH carries the BCCH, the power of the HS-SCCH is determined by the offset relative to the P-CPICH power. The offset is specified by BcchHsscchPower.



When the UE is in the enhanced CELL_FACH state and the HS-PDSCH carries the user data, the power control method for the HS-SCCH can be fixed (fixed transmit power control) or CQI-based (dynamic transmit power control). The method is specified by HsScchPwrCMInEfach. − Fixed

transmit power control: The power of the HS-SCCH is determined by the offset relative to the P-CPICH power. The offset is specified by BcchHsscchPower.

− Dynamic

transmit power control based on CQI: The NodeB converts the measured CPICH Ec/N0 into CQI, based on which the transmit power of the HS-SCCH is estimated. NOTE

Because there is no corresponding interface for the UE to report the measured CPICH Ec/N0 to the NodeB, the UE obtains the measured CPICH Ec/N0 and reports the value to the RNC, and then the RNC assigns the measured CPICH Ec/N0 to the NodeB over the HS-DSCH.

5.2.3 Power Control on HS-SCCH in Enhanced CELL_PCH/URA_PCH When the UE in the enhanced CELL_PCH/URA_PCH state receives downlink data from the HS-PDSCH, the UE does not return any ACK/NACK response or CQI information. In this case, the power of the HS-SCCH is determined by the offset relative to the P-CPICH power. The offset is specified by EPCHHSSCCHPower. A high value of this parameter leads to power waste; a low value of this parameter decreases the HS-SCCH demodulation success rate and paging success rate.

6 HSUPA Power Control

6 HSUPA Power Control This chapter describes the feature WRFD-01061203 HSUPA Power Control.

6.1 Power Control on E-DPCCH The transmit power on the E-DPCCH is calculated using a power offset reference to the uplink DPCCH with the following formula: PE-DPCCH = PUL DPCCH x A2ec where 

PUL DPCCH is the transmit power of the uplink DPCCH.



Aec is the quantized amplitude ratio of the E-DPCCH to the uplink DPCCH, which is set to 15/15 for a 2 ms TTI and 9/15 for a 10 ms TTI.

If the UE is enabled with E-DPCCH Boosting, Aec is calculated by using a new method. For details about the new method, see HSPA Evolution Feature Parameter Description.

6.2 Power Control on E-DPDCH The transmit power on the E-DPDCH is calculated using a power offset reference to the uplink DPCCH with the following formula: PE-DPDCH = PUL DPCCH x A2ed where 

PUL DPCCH is the transmit power of the uplink DPCCH.



Aed is the power offset of the E-DPDCH reference to the uplink DPCCH. The UE computes the power offset through power extrapolation formula or power interpolation formula. Compared with extrapolation formula, the interpolation formula can satisfy higher demodulation requirement for high speed services. The extrapolation formula will be used only when the following conditions are met: − PcSwitch:

PC_CFG_ED_POWER_INTERPOLATION_SWITCH is set to 1.

− The

UE complies with 3GPP Release 7 or later releases.

− The

typical variables to support extrapolation formula are configured.

If the previous conditions are not met, the interpolation formula will be used. For detail information about power extrapolation formula and power interpolation formula, see 3GPP TS 25.214.

6.3 E-DCH Outer Loop Power Control Outer loop power control on the E-DCH is used to adjust the transmit power on the E-DPDCH and to keep the QoS of the E-DCH on the required level. The QoS on the E-DCH is obtained after the RNC performs a macro diversity combination. Since only the correct packets are sent to the RNC from the NodeB, the number of HARQ retransmissions is used as the measurement for the E-DCH QoS. Outer loop power control periodically adjusts the SIRtarget, related to the service QoS for the E-DCH, in a similar way for the DCH. The control object of outer loop power control can be the number of retransmissions (NHR) or the residual BLER (RBLER).



6-1





If the service is interactive/background/streaming/SRB, NHR is the control object of outer loop power control.



If the service is PS conversational, RBLER is the control object of outer loop power control. NOTE

The DCH outer loop power control algorithm described in section 4.4 "Outer Loop Power Control" and E-DCH outer loop power control algorithm described in this section allow the uplink SIR target to quickly increase but slowly decrease, which wastes uplink power and affects cell uplink capacity. To address this problem, outer loop power control is enhanced. For details, see section 7.1.3 "Outer Loop Power Control Enhancement."

6.4 Power Control on E-AGCH, E-RGCH, and E-HICH Overview In the downlink, HSUPA has three additional control channels: E-AGCH, E-RGCH, and E-HICH. The following power control methods are used: 

Power Control Based on Fixed Power



Power Control Based on Downlink DPCH/F-DPCH, including power control based on TPC and power control based on pilot



HSUPA E-AGCH Power Control (Based on CQI or HS-SCCH), including power control based on CQI and power control based on HS-SCCH

The power control methods can be configured on the NodeB for each channel through the following parameters: 

EAGCHPCMOD (E-AGCH power control mode)



NSEHICHPCMOD (non-serving E-HICH power control mode)



SEHICHPCMOD (serving E-HICH power control mode)



NSERGCHPCMOD (non-serving E-RGCH power control mode)



SERGCHPCMOD (serving E-RGCH power control mode)

These parameters may have the value of FIXED, FOLLOW_TPC, RNC_BASED, CQI_BASED, or HSSCCH_BASED, as listed in Table 6-1. Table 6-1 Parameter values and corresponding power control methods Parameter Value

6.4.2 Power Control Based on Fixed Power If the power control based on the fixed power is used, the transmit power on the E-AGCH, E-RGCH, and E-HICH is calculated with the following formula: PE-AGCH = PP-CPICH + POE-AGCH PE-RGCH = PP-CPICH + POE-RGCH PE-HICH = PP-CPICH + POE-HICH where 

PE-AGCH, PE-RGCH, and PE-HICH are the transmit power of the E-AGCH, E-RGCH, and E-HICH, respectively,



PP-CPICH is the transmit power of the P-CPICH.



POE-AGCH, POE-RGCH, and POE-HICH are the power offsets of the E-AGCH, E-RGCH, and E-HICH relative to the transmit power of the P-CPICH, respectively. These power offsets are used to calculate the transmit power of E-AGCH, E-RGCH, and E-HICH, respectively in different scenarios.

The power offset is configured on the NodeB through the following parameters. 

EAGCHPower (E-AGCH power)



SERGCHPower (Serving E-RGCH power)



NSERGCHPower (Non-serving E-RGCH power)



SingleRLEHICHPower (Single RL E-HICH power)



SEHICHPower (Serving E-HICH power)



NSEHICHPower (Non-serving E-HICH power)

6.4.3 Power Control Based on Downlink DPCH/F-DPCH The demodulation conditions of HSUPA downlink control channels are similar to those of the TPC or pilot field of the downlink DPCH/F-DPCH. Therefore, the power of HSUPA downlink control channels can be controlled based on the TPC or pilot field. The power based on TPC is similar to the power control based on pilot. Therefore, only the power control based on TPC is described in this section. The HSUPA transmit power is calculated with the following formula: P = PTPC + FUNC(PowOffset) where 

P is the transmit power of the E-AGCH, E-RGCH, or E-HICH.



PTPC is the transmit power of the TPC field on the DL DPCH or F-DPCH.



PowOffset is the power offset of the specific channel reference to the DPCCH TPC field. − EAGCHPWROFFSET

6.4.4 HSUPA E-AGCH Power Control (Based on CQI or HS-SCCH) This section describes the feature WRFD-01061401 E-AGCH Power Control (Based on CQI or HS-SCCH). The HSUPA E-AGCH power control is based on the serving cell. The serving HSUPA cell must be consistent with the serving HSDPA cell. Therefore, the HSDPA information can be used for HSUPA E-AGCH power control. The available HSDPA information of CQI and HS-SCCH is discontinuous. Therefore, the HSUPA E-AGCH power control still depends on the power control based on the downlink DPCH/F-DPCH. When the HSDPA information of CQI or HS-SCCH is available, the information can be used to adjust the results of the power control. Otherwise, the power control based on the DPCH/F-DPDCH is used directly on the E-AGCH. The procedure of power control based on HSDPA is as follows: 1. The NodeB obtains the power offset of the E-AGCH calculated by the power control based on the downlink DPCH/F-DPCH. 2. If the HS-SCCH is transmitting data and using dynamic power control, the NodeB updates the E-AGCH power offset based on the HS-SCCH power. 3. If the HS-SCCH is not available and the NodeB receives CQIs from the UE, the CQIs are used to update the power offset of the E-AGCH. 4. The NodeB calculates the E-AGCH power based on the updated power offset. The E-AGCH power is limited by the maximum value of (P-CPICH power + MAXAGCHPOWER) and the minimum value of (P-CPICH power + MINAGCHPOWER). MAXAGCHPOWER and MINAGCHPOWER are set on the NodeB.

7 Power Control Enhancement

7 Power Control Enhancement 7.1 DCH Power Control 7.1.1 DPCH Pilot Power Adjustment This section describes the WRFD-150230 DPCH Pilot Power Adjustment feature, which correlates with "Power of Downlink DPCCH" in section 4.2.2 "Downlink Open Loop Power Control on DPCH."

Overview Downlink DPCHs consist of the downlink DPDCH and DPCCH. As a part of the DPCCH, the pilot field is used for UEs to estimate the signal-to-interference ratio (SIR) during the inner loop power control procedure and to determine whether radio links are synchronized. When the cell load is light, the pilot field can be assigned with higher transmit power and a longer bit length to increase the accuracy of SIR estimations and Uu-interface synchronization probability. When a cell serves a large number of UEs, downlink R99 services consume a large amount of downlink power. As a result, the remaining downlink power becomes insufficient to admit potential UEs. In addition, the amount of downlink power available for HSDPA services decreases, which reduces HSDPA throughput. In this situation, the WRFD-150230 DPCH Pilot Power Adjustment feature is introduced. This feature saves DPCH power by configuring a shorter bit length and a smaller power offset for the pilot field. The saved power can admit more UEs or increase HSDPA throughput.

Technical Description This feature is controlled by PC_PILOT_PO_OPTI_SWITCH under the PcSwitch parameter. 

When downlink non-HSPA power load in a cell is equal to or larger that the value specified in the LoadStateForPilotPwrAdj parameter, this feature configures the bit length and pilot-field power offset as follows during the initial access process: − Bit

length

1. If real-time services (conversational services (including emergency calls) or streaming services) are not established on the downlink DPCH, the bit length is determined by the value of the DlDpchSf256OptiPilotBit parameter if the spreading factor for the downlink DPCH is 256. 2. If real-time services (conversational services (including emergency calls) or streaming services) are established on the downlink DPCH, the bit length is determined by the value of the DlDpchSf256PilotBit parameter if the spreading factor for the downlink DPCH is 256. − Pilot-field

power offset

1. If real-time services (conversational services (including emergency calls) or streaming services) are not established on the downlink DPCH, the pilot-field power offset is determined by the value of the NonCsOptiPilotPo parameter. 2. If real-time services (conversational services (including emergency calls) or streaming services) are established on the downlink DPCH, the pilot-field power offset is determined by the value of the CsOptiPilotPo parameter. 

When downlink non-HSPA power load in a cell is smaller than the value specified in the LoadStateForPilotPwrAdj parameter, the bit length is determined by the value of the DlDpchSf256PilotBit parameter and the pilot-field power offset is determined by the value of the PilotPO parameter. Note that the spreading factor of the DPCH must be 256.



7-1



NOTE

DPCH pilot-filed power offset configuration during the initial access process occurs when the downlink DPCH is established in any of the following scenarios: 

The UE initiates an RRC connection setup process in the cell the UE accesses.



The UE transits from the URA_PCH, CELL_PCH or CELL_FACH state to the CELL_DCH state.



The UE is performing an incoming inter-cell hard handover process.



The UE falls back from HSDPA channels to R99 channels.

For descriptions of the power load state specified by the LoadStateForPilotPwrAdj parameter, see related descriptions in section 3.1 "Load-related Measurement Quantities" of Load Control Feature Parameter Description.

7.1.2 DPCH Maximum Power Restriction This section describes the WRFD-150235 DPCH Maximum Power Restriction feature, which correlates with "Initial Power of Downlink DPDCH" in section 4.2.2 "Downlink Open Loop Power Control on DPCH."

Overview The downlink A-DPCH is used to transmit signaling messages and perform power control. When HSPDA services are being connected, the A-DPCH consumes downlink power even though there are no signaling messages to transmit. If a cell serves a large number of HSDPA UEs, the A-DPCH will consume a large amount of downlink power and the amount of power available for channels that transmit HSDPA data is greatly reduced. In this situation, the WRFD-150235 DPCH Maximum Power Restriction feature is introduced. This feature effectively controls the maximum transmit power of the downlink A-DPCH, which promotes downlink system capacity.

Technical Description This feature is controlled by the dpchMaxTxPwrRestrSw parameter on the NodeB side. 

When downlink non-HSPA power load in a cell is heavier than the sum of threshold corresponding to dpchMaxPwrRtrLoadStat and 10%: − Maximum

downlink transmit power (RlMaxDlPwr) for the A-DPCH is reduced if there are no signaling messages transmitted on the A-DPCH.

− The

original setting of RlMaxDlPwr is restored if signaling messages are being transmitted on the A-DPCH.



After this feature takes effect, if downlink non-HSPA power load in a cell is lighter than the difference of threshold corresponding to dpchMaxPwrRtrLoadStat and 10%, this feature becomes invalid and the original setting of the RlMaxDlPwr parameter is restored. NOTE

This feature applies only to non-voice services and the downlink DPCH can only carry HSDPA UEs using 3.4 kbit/s SRBs.

7.1.3 Outer Loop Power Control Enhancement This function involves outer loop power control and E-DCH outer loop power control, which are described in sections 4.4 "Outer Loop Power Control" and 6.3 "E-DCH Outer Loop Power Control."

Overview Legacy outer loop power control algorithms based on the BLER/BER/RBLER/NHR allow the SIR target to quickly increase but slowly decrease when the target BLER/BER/RBLER/NHR is low. These algorithms ensure that the BLER/BER/RBLER/NHR converges to the target value. When channel conditions deteriorate, there is burst interference, the UE transmit power is insufficient, or cell capacity is limited, a



7-2



large number of consecutive error blocks may occur, and the SIRtarget and RTWP will increase abruptly. When channel conditions become satisfactory, the UE transmit power becomes sufficient, or cell capacity is no longer limited, the SIRtarget decreases slowly. As a result, the cell uplink power remains high for a long time, wasting uplink power and reducing cell uplink capacity. Outer loop power control is enhanced to allow a quick increase or decrease in the SIRtarget, for example, when RB establishment or reconfiguration is complete, there is burst interference, or UE transmit power is insufficient. In these scenarios, the enhanced feature reduces the uplink power waste. When the RTWP increases abnormally due to limited cell capacity, the NodeB adjusts the SIRtarget sent from the RNC to prevent a continuous RTWP increase caused by the SIRtarget increase.

Technical Description In scenarios where uplink power is wasted, outer loop power control enhancement adjusts the SIRtarget differently from the legacy outer loop power control algorithms as follows: Scenario

Outer Loop Power Control

Outer Loop Power Control Enhancement

RB establishment The initial SIRtarget (InitSirtarget) is set or reconfiguration to a large value to increase the RB establishment success rate. However, it takes a long time for the SIRtarget to decrease to the convergence value of the SIRtarget (RefSIRtarget) when RB establishment or reconfiguration is complete, wasting uplink power.

The enhanced feature uses a larger step to decrease the SIRtarget so that the SIRtarget quickly decreases when RB establishment or reconfiguration is complete.

Burst interference

A large number of consecutive error blocks result in a sudden SIRtarget increase. However, the SIRtarget slowly decreases to a proper value after the interference is eliminated, resulting in wasted uplink power.

The enhanced feature disables SIRtarget adjustment in a specified time to prevent sudden SIRtarget increases caused by short-term burst interference.

UE transmit power insufficiency

A large number of consecutive error blocks result in a sudden SIRtarget increase. However, the SIRtarget slowly decreases to a proper value after the UE transmit power becomes sufficient. Therefore, uplink power is wasted when UE transmit power becomes sufficient.

The enhanced feature sets the SIRtarget to the initial SIRtarget (InitSirtarget) when the UE transmit power becomes insufficient, and uses a larger step to decrease the SIRtarget so that the SIRtarget quickly decreases when UE transmit power becomes sufficient.

RTWP abnormal increase

A large number of consecutive error blocks result in a sudden SIRtarget increase. Then, the RTWP continuously increases, affecting cell capacity.

The enhanced feature adjusts the SIRtarget sent from the RNC to the NodeB to prevent a continuous RTWP increase caused by the SIRtarget increase.

RB Establishment or Reconfiguration In this scenario, the enhanced feature is controlled by PC_OLPC_FastDown_Optimize_SWITCH under the PCSwitch parameter. Figure 7-1 shows the procedure for an SIRtarget quick decrease in the RB establishment or reconfiguration scenario.



7-3



Figure 7-1 Flowchart for an SIRtarget quick decrease in the RB establishment or reconfiguration scenario

In Figure 7-1, decision condition 1 specifies whether a UE meets the requirements for an SIRtarget quick decrease. The RNC determines that a UE meets decision condition 1 if one of the following conditions is met: 

Services carried on a DCH The current SIRtarget is larger than the reference SIRtarget (RefSIRtarget) and the current BLER is 0.



Services carried on an E-DCH − RBLER-based

outer loop power control: The current SIRtarget is larger than the reference SIRtarget (RefSIRtarget) and the current RBLER is 0.

− NHR-based

outer loop power control: The current SIRtarget is larger than the reference SIRtarget (RefSIRtarget) and the current NHR is 0.

As shown in Figure 7-1, when RB establishment or reconfiguration is complete, the RNC sets the SIRtarget to the initial SIRtarget (InitSirtarget) and counter n to the value of 0, and enables the SIRtarget quick decrease. In the next outer loop power control period, the RNC determines whether a UE meets decision condition 1. If the UE meets decision condition 1, the RNC decreases the SIRtarget using the step specified by ΔSIRtar(n), and adds 1 to counter n until n reaches the maximum value N. N is the ratio



7-4



of the maximum range of the SIRtarget quick decrease to SIRtargetDownSpeed, which is calculated in the following formula: N = (InitSirtarget – RefSIRtarget)/SIRtargetDownSpeed In each subsequent outer loop power control period, the RNC determines whether the UE meets decision condition 1 and whether n is less than or equal to N repeatedly. The SIRtarget quick decrease amount ΔSIRtar(n) is calculated in the following formula: ΔSIRtar(n) = –SIRtargetDownSpeed x SirAdjustPeriod NOTE

SirAdjustPeriod specifies the outer loop power control period. This period is RAB-specific. For details, see section 4.4 "Outer Loop Power Control."

The RNC exits the SIRtarget quick decrease mode to avoid the block error rate increase if the UE does not meet decision condition 1 or n is larger than N in an outer loop power control period. For example, the BLER/RBLER/NHR is larger than 0, or the current SIRtarget is equal to or smaller than the reference SIRtarget (RefSIRtarget). RefSIRtarget is the convergence value of the SIRtarget when RB establishment or reconfiguration is complete. The maximum range of the SIRtarget quick decrease is equal to the difference between InitSirtarget and RefSIRtarget. Therefore, the value of RefSIRtarget must be equal to or smaller than the value of InitSirtarget. Otherwise, the SIRtarget quick decrease cannot be enabled. After exiting the SIRtarget quick decrease, the RNC decreases the SIRtarget according to the procedure defined in section 4.4 "Outer Loop Power Control" or section 6.3 "E-DCH Outer Loop Power Control." After RB reconfiguration, if the SIR on the DPCCH drastically increases from a low level to a high level, the NodeB still uses the low SIR when RB configuration has taken effect, because PC_RL_RECFG_SIR_TARGET_CARRY_SWITCH under the PcSwitch parameter of the RNC is turned off by default. As a result, this feature yields no uplink capacity gains. If uplink capacity gains are required in this scenario, it is recommended that PC_RL_RECFG_SIR_TARGET_CARRY_SWITCH under the PcSwitch parameter of the RNC be turned on by using the SET UCORRMALGOSWITCH command and PERFENH_RL_RECFG_SIR_CONSIDER_SWITCH under the PerfEnhanceSwitch parameter of the RNC be turned on by using the SET UCORRMPAR command.

Burst Interference In this scenario, the enhanced feature is controlled by PC_OLPC_FastDown_Optimize_SWITCH under the PCSwitch parameter. If there is burst interference, the block error rate of the UE is extremely high. The SIRtarget quickly increases if the RNC uses a legacy outer loop power control algorithm. However, the SIRtarget slowly decreases to a proper value after the interference is eliminated, wasting uplink power. The enhanced feature disables SIRtarget adjustment in a specified time to prevent sudden SIRtarget increases caused by short-term burst interference. Burst interference is indicated by RTWP peaks. Figure 7-2 shows the procedure for an SIRtarget quick decrease in the burst interference scenario.



7-5



Figure 7-2 Flowchart for an SIRtarget quick decrease in the burst interference scenario

In Figure 7-2, decision condition 2 specifies whether a UE is experiencing burst interference. The RNC determines that a UE meets decision condition 2 if one of the following conditions is met: 

Services carried on a DCH The BLER in an outer loop power control period is equal to or higher than the preset threshold. The preset threshold is fixed at 50%.



Services carried on an E-DCH − RBLER-based



Counter k reaches the maximum value K. The formula for calculating the value of K is as follows: K = ceil{100 ms/SirAdjustPeriod}.

As shown in Figure 7-2, after determining that a UE is experiencing burst interference in an outer loop power control period, the RNC adjusts the SIRtarget using a legacy outer loop power control algorithm in the current outer loop power control period, and initializes counter k to the value of 0. Counter k records the number of outer loop power control periods in which the SIRtarget cannot be adjusted. The maximum value of Counter k is K. The formula for calculating the value of K is as follows: K = ceil{100 ms/SirAdjustPeriod}. In each subsequent outer loop power control period, if the UE meets decision condition 2 and counter k value does not reach the maximum, the RNC does not adjust the SIRtarget. If the UE does not meet decision condition 2 or counter k reaches the maximum value K, the RNC determines that the UE is not experiencing burst interference and adjusts the SIRtarget using a legacy outer loop power control algorithm. In addition, the RNC initializes counter k to the value of 0. After determining that a UE is not experiencing burst interference, the RNC decreases the SIRtarget according to the procedure defined in section 4.4 "Outer Loop Power Control" or section 6.3 "E-DCH Outer Loop Power Control."

UE Transmit Power Insufficiency In this scenario, the enhanced feature is controlled by PC_OLPC_FastDown_Optimize_SWITCH under the PCSwitch parameter. The RNC sends the NodeB a DEDICATED MEASUREMENT INITIATION REQUEST message containing the measurement object of the SIRerror. The SIRerror is equal to the actual SIR minus the SIRtarget. The NodeB reports event F to the RNC. Event F consists of event Fa and event Fb. 

If the SIRerror is lower than the threshold (–3 dB) of event Fa for a period of time (80 ms), event Fa is triggered.



If the SIRerror is equal to or higher than the threshold (–3 dB) of event Fb for a period of time (80 ms), event Fb is triggered.

If the RNC receives the measurement report containing the event Fa from all the radio link sets of a UE, the RNC determines that the link quality is poor and the UE transmit power is insufficient. Then, the RNC sets the SIRtarget to the initial SIRtarget (InitSirtarget) and disables SIRtarget adjustment. In this way, the transmit power insufficiency does not raise the SIRtarget excessively. After the UE transmit power becomes sufficient, less uplink power is wasted. If the RNC receives the measurement report containing the event Fb from any radio link set of the UE, the RNC determines that the link quality resumes and the UE transmit power becomes sufficient. Then, the RNC enables the SIRtarget quick decrease. For details, see section "RB Establishment or Reconfiguration."

RTWP Abnormal Increase In this scenario, the enhanced feature is controlled by RTWPSIRTGTADJSW. When the RTWP increases abnormally due to limited cell capacity, the NodeB determines the RTWP abnormal increase scenario according to the slight congestion threshold and severe congestion threshold, and adjusts the SIRtarget from the RNC for DTX UEs and non-DTX UEs separately. This decreases the RTWP or increases cell uplink capacity.



7-7



NOTE 

HSUPA UEs with no data transmission for more than 200 ms are regarded as DTX UEs. When data transmission resumes, the HSUPA UEs are regarded as non-DTX UEs.



UEs over DCH are regarded as non-DTX UEs by default.

For details about DTX, see HSPA Evolution Feature Parameter Description.

Figure 7-3 shows the procedure for enhanced outer loop power control in the RTWP abnormal increase scenario. 1. The NodeB determines the RTWP abnormal increase scenario according to the slight congestion threshold and severe congestion threshold, adjusts the SIRtarget from the RNC, and reports the UE congestion indication to the RNC. 2. The RNC adjusts the SIRtarget according to the UE congestion indication reported by the NodeB. If the UE congestion indication is "Congested", the RNC keeps the maximum SIRtarget unchanged in a specified time to prevent a continuous SIRtarget increase. Figure 7-3 Flowchart for enhanced outer loop power control in the RTWP abnormal increase scenario

The following describes the procedure for enhanced outer loop power control in the RTWP abnormal increase scenario. 3. The NodeB adjusts the SIRtarget received from the RNC for different types of UE. The SIRtarget is adjusted as follows: 

SIRtarget = max{SIRtarget from the RNC + min{DCHDeltaSIRtargeti, i=1,...}, min{SIRtarget from the RNC, 0 dB}} A UE has only one SIRtarget.

When multiple radio links have been established on the UE, the radio link with the smallest adjustment (EDCHDTXDeltaSIRtarget or EDCHnonDTXDeltaSIRtarget) is used for calculating the SIRtarget. 

For a DTX UE over E-DCH SIRtarget = max{SIRtarget from the RNC + min{EDCHDTXDeltaSIRtargeti, i=1,...}, min{SIRtarget from the RNC, 0 dB}} A UE has only one SIRtarget. When multiple radio links have been established on the UE, the radio link with the smallest adjustment (EDCHDTXDeltaSIRtarget) is used for calculating the SIR target. NOTE

The subscript "i" indicates the radio link number in the radio link set.

The three SIRtarget adjustments adjust from the initial value as follows: 

If the real-time RoT of the cell reaches the slight congestion threshold, the NodeB decreases EDCHDTXDeltaSIRtarget with the SIRtarget decrease step. If the real-time RoT of the cell is below the slight congestion threshold, the NodeB increases EDCHDTXDeltaSIRtarget with the SIRtarget increase step.



If the real-time RoT of the cell reaches the severe congestion threshold, the NodeB decreases EDCHnonDTXDeltaSIRtarget and DCHDeltaSIRtarget with the SIR target decrease step. If the real-time RoT of the cell is below the severe congestion threshold, the NodeB increases EDCHnonDTXDeltaSIRtarget with the SIRtarget increase step and sets DCHDeltaSIRtarget to 0. NOTE



Slight congestion threshold = real-time target RoT + 2 dB



SIRtarget increase step: equal to 0.02 dB by default for the DTX UE over E-DCH, non-DTX UE over E-DCH, and non-DTX UE over DCH

4. The NodeB sets the UE congestion indication. The NodeB sets the UE congestion indication to "Congested" if the following conditions are met: 



For an R99 UE SIRtarget adjustment: min{DCHDeltaSIRtargeti, i=1,...} ≠ 0 If the conditions above are not met, the NodeB sets the UE congestion indication to "Not Congested." NOTE

The subscript "i" indicates the radio link number in the radio link set.

5. The RNC sets the maximum SIRtarget according to the UE congestion indication reported by the NodeB. The initial UE congestion indication is "Not Congested." 

If the RNC receives a UE congestion indication set to "Congested", the RNC sets the UE status to "Congested" and the maximum SIRtarget to min{current SIRtarget, INITSIRTARGET}. At the same time, the RNC starts a 50 ms timer and keeps the maximum SIRtarget unchanged until the timer expires. If the RNC has not received a potential UE congestion indication before the timer expires, it sets the UE status to "Not Congested" and the maximum SIRtarget to MAXSIRTARGET.



If the RNC does not receive the UE congestion indication, the maximum SIRtarget of the UE is equal to MAXSIRTARGET.

The BTS3812E, BTS3812A, or BTS3812AE must be configured with the EBBI or EBOI board. Alternatively, these base stations must be configured with the EULP and EDLP boards, or the EULPd and EDLP boards. Downlink services must be established on the EBBI or EBOI, or the EDLP board (The EDLP board processes HSPA services).





3900 series base stations must be configured with the WBBPb, WBBPd, or WBBPf board, and downlink services must be established on the WBBPb, WBBPd, or WBBPf board.

7.2 HSUPA Power Control 7.2.1 Adaptive Configuration of Traffic Channel Power Offset for HSUPA This section describes the feature WRFD-010712 Adaptive Configuration of Traffic Channel Power offset for HSUPA. This feature involves E-DCH outer loop power control, which is described in section 6.3 "E-DCH Outer Loop Power Control." Nowadays, HSPA and HSPA+ are a mainstream technology in the communication industry. Uplink system performance needs to be enhanced to adapt to ever-increasing HSUPA peak rates. The Adaptive Configuration of Traffic Channel Power offset for HSUPA feature increases the HSUPA capacity of networks. This feature monitors changes in the uplink data rates of UEs and uplink network load and adaptively configures optimal power control parameter settings for the uplink data channels. This configuration helps reduce the uplink DPCCH transmit power of UEs in the low-rate little retransmission state. The offset of E-DPDCH power relative to DPCCH RX power is one of the major factors that determine the DPCCH RX power. A UE in low-rate little retransmission state requires less DPCCH RX power than it does in high-rate little retransmission state. Figure 7-4 shows the difference in DPCCH RX power for a UE in different data transmission states. In Figure 7-4, DPCCH RX power adjustment by inner loop power control is ignored and a constant power value is used instead. In practical applications, the value of DPCCH RX power fluctuates. Issue Draft A (2013-01-30)

Figure 7-4 DPCCH RX power in the small and large retransmission states without this feature

This feature is activated when PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SWITCH under the PcSwitch parameter is selected and the uplink load reaches MaxTargetUlLoadFactor. When HSUPA UEs are in the little retransmission state, this algorithm configures the optimal power offset for UEs based on the changes of uplink load and throughput. In this way, the DPCCH RX power remains at the optimum level and the HSUPA capacity in the related cell increases when multiple UEs access the network. Figure 7-5 shows the DPCCH RX power for UEs in the small and large retransmission states when this feature is enabled. When the feature HSUPA Adaptive Transmission is enabled for UEs, the UEs are in the large retransmission state if the uplink cell load or UE transmit power is limited. Otherwise, the UEs are in the little retransmission state. For detailed decisions about whether uplink cell load or UE transmit power is limited, see chapter "HSUPA Adaptive Retransmission" in HSUPA Feature Parameter Description. Figure 7-5 DPCCH RX power in the small and large retransmission states with this feature

The little retransmission state can be classified into high-rate little retransmission state or low-rate little retransmission state according to the date rate. When the average data rate of a UE is lower than the value of EdPOAdpAdjRateDnThd, and the uplink load of the cell is larger than MAXTARGETULLOADFACTOR * TrigRatioforUlRTWP, the UE is in the low-rate little retransmission state. For a UE in the low-rate little retransmission state, HarqPOLitRetrLRate specifies the Hybrid Automatic Repeat reQuest (HARQ) power offset. A larger Issue Draft A (2013-01-30)


7-11



HARQ offset increases the E-DPDCH power offset, decreases the DPCCH RX power, and reduces the power consumed on the uplink control channel. The saved power can be used by data channels, thereby increasing the HSUPA capacity in the cell. When the average data rate of a UE is higher than the value of EdPOAdpAdjRateDnThd, the UE is in high-rate little retransmission state. For a UE in the high-rate little retransmission state, HarqPOLitRetrHRate specifies the HARQ offset. The DPCCH RX power can be adjusted by setting HarqPOLitRetrHRate to different values to ensure that the HSUPA performance does not deteriorate. For a UE in the large retransmission state, HarqPOLargeRetr specifies the HARQ offset. The HARQ offset can be set to a proper value to ensure a stable DPCCH RX power. NOTE 

If dynamic CE takes effect, the RNC configures the HARQ PO based on the real-time data rate of services. If DCCC takes effect, the RNC configures the HARQ PO based on the real-time data rate of services.



The HARQ PO is one of the variables for determining the power offset on the E-DPDCH relative to the DPCCH.

Penalty Mechanism When PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SWITCH and PC_HSUPA_HARQNUM_AUTO_ADJUST_SWITCH under the PcSwitch parameter are selected, an E-DPDCH power offset reconfiguration procedure starts if the retransmission state of a UE changes. PC_HSUPA_HARQNUM_AUTO_ADJUST_SWITCH under the PcSwitch parameter selected indicates that the HSUPA adaptive retransmission algorithm is enabled. In the E-DPDCH power offset reconfiguration procedure, the Uu interface signaling is reconfigured. This consumes radio resources and may affect key performance indicators (KPIs) such as the call drop rate. Therefore, the frequency of retransmission state adjustments needs to be controlled. To control the frequency of retransmission state adjustments, a penalty timer AdapRetranPunTimer is configured at the RNC. This timer starts when the number of target retransmissions for a UE is adjusted. Before the timer expires, the RNC is not allowed to adjust the number of target retransmissions, regardless of whether the NodeB sends retransmission state adjustment requests in this period. After the timer expires, the RNC adjusts the number of target retransmissions according to the NodeB's requests.

7.2.2 Initial Power Offset Selection for HSUPA Traffic Channels This feature involves E-DCH outer loop power control, which is described in section 6.3 "E-DCH Outer Loop Power Control." In the Adaptive Configuration of Traffic Channel Power offset for HSUPA algorithm, the initial HARQ power offset is set to the HarqPOLitRetrHRate parameter value as in the high-rate little retransmission state. This algorithm takes more than 2s to adjust the pilot-field power offset to the HarqPOLitRetrHRate parameter value. However, in live networks, there are services with a low traffic volume, and the data transmission duration may be shorter than 2s. Therefore, this algorithm does not apply in scenarios with short data transmission durations. To address the preceding issue, the algorithm of initial power offset selection for HSUPA traffic channels is introduced. With this algorithm, the RNC can directly set the initial HARQ power offset to the HarqPOLitRetrLRate parameter value that is used for the low-rate little retransmission state. This algorithm helps increase cell capacity. PC_HSUPA_DATA_CH_PO_INIT_SEL_SWITCH under the PcSwitch parameter controls the algorithm for the initial power offset selection for HSUPA traffic channel. After PC_HSUPA_DATA_CH_PO_INIT_SEL_SWITCH is selected, HarqPOLitRetrLRate is used as the initial power offset for low-rate data transmission during the RAB setup or UE state transition from other connected states (CELL_FACH, CELL_PCH, and URA_PCH) to CELL_DCH. When



7-12



PC_HSUPA_DATA_CH_PO_INIT_SEL_SWITCH is cleared and PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SWITCH is selected, the initial power offset is set according to the adaptive configuration of traffic channel power offset for HSUPA. For details, see section 7.2.1 "Adaptive Configuration of Traffic Channel Power Offset for HSUPA." When PC_HSUPA_DATA_CH_PO_INIT_SEL_SWITCH OFF and PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SWITCH are set to OFF, the initial power offset is set to 0. When the algorithm is enabled for the initial power offset selection for HSUPA traffic channels, configure a relatively high HARQ power offset by setting HarqPOLitRetrLRate, to increase the E-DPDCH power offset. At a same data transmission rate, this algorithm can reduce the DPCCH RX power and the load on uplink control channels. The reduced load can be reused by other traffic channels, and consequently contribute to an expanded HSUPA capacity. When the data transmission time is short and the data volume is small, the HSUPA capacity increases more remarkable.

7.2.3 HSUPA Coverage Enhancement at UE Power Limitation This section describes the feature WRFD-020138 HSUPA Coverage Enhancement at UE Power Limitation. This feature involves power control on E-DPDCH, which is described in section 6.2 "Power Control on E-DPDCH". This feature improves the UE experience at the cell edge and expands the coverage at the HSUPA cell edge for BE services and voice services. This feature reduces the call drop rate at the cell edge and ensures service continuity. When PC_HSUPA_COVER_EN_AT_POLIMIT_SWITCH under the PcSwitch parameter is selected, this feature is enabled. When a UE detects that its transmit power is limited, the UE enters power scaling mode to ensure that its total transmit power does not exceed the maximum. If uplink enhanced layer 2 is not enabled, the UE transmit power will be limited when the uplink RLC-layer rate of the UE is equal to the minimum RLC-layer rate. If uplink enhanced layer 2 is enabled, the UE transmit power will be limited when the uplink MAC-layer rate of the UE is equal to the rate of the MAC-layer minimum size transport block. For details about uplink enhanced layer 2, see HSPA Evolution. In HSUPA power scaling mode, the power offset of E-DPDCH relative to DPCCH is reduced to the minimum value (BetaEdMin). In this case, data transmission at the cell edge may be interrupted because of limited transmit power. In enhanced power scaling mode, the minimum value of the power offset of E-DPDCH relative to DPCCH is larger than that in HSUPA power scaling mode. That is, the ratio of E-DPDCH power to the maximum transmit power increases. This ensures a high E-DPDCH power and therefore expands the coverage of HSUPA services. For details about this feature, see 3GPP TS 25.214.

WRFD-150230 DPCH Pilot Power Adjustment This feature can be activated together with the WRFD-150230 DPCH Pilot Power Adjustment feature for a cell. For HSDPA UEs, the WRFD-150230 DPCH Pilot Power Adjustment feature reduces the transmit power of the pilot field on the A-DPCH. The WRFD-150235 DPCH Maximum Power Restriction feature reduces the maximum transmit power of the A-DPCH. When downlink load in a cell is heavy, the two features can be used together to provide more noticeable power reduction gains. However, this may reduce the accuracy of SIR estimations and increase the call drop rate for HSDPA UEs.

9 Network Impact 9.1 WRFD-010712 Adaptive Configuration of Traffic Channel Power offset for HSUPA 9.1.1 System Capacity This feature noticeably increases the HSUPA capacity of cells with a large number of HSUPA UEs and low data rates. During busy hours at sites with high UE density, a large number (for example, 20 to 30) of HSUPA UEs may transmit data simultaneously. Uplink load is heavy, and the HSUPA capacity of the cell may decrease. This feature effectively increases HSUPA capacity for cells without raising the target load. After this feature is activated in a cell accommodating 2 ms TTI and 10 ms TTE UEs, 

The average HSUPA throughput in the cell may increase.



The number of UEs that can transmit data simultaneously in the uplink may increase.



The RTWP may be reduced.

The gain provided by this feature is 5% to 20%.

9.2 WRFD-020138 HSUPA Coverage Enhancement at UE Power Limitation 9.2.1 System Capacity No impact.

9.2.2 Network Performance This feature improves coverage of BE and voice services over HSUPA channels at the cell edge. Simulation test results show that the coverage can be increased by about 10%.

9.3 WRFD-020503 Outer Loop Power Control 9.3.1 System Capacity The enhanced feature allows SIRtarget quick adjustment in scenarios of service establishment or reconfiguration, burst interference, and UE transmit power insufficiency. The enhanced feature reduces the uplink power waste and increases cell uplink capacity. After RB reconfiguration, if the SIR on the DPCCH drastically increases from a low level to a high level, the NodeB still uses the low SIR when RB configuration has taken effect, because PC_RL_RECFG_SIR_TARGET_CARRY_SWITCH under the PcSwitch parameter of the RNC is turned off by default. As a result, this feature yields no uplink capacity gains. If uplink capacity gains are required in this scenario, it is recommended that PC_RL_RECFG_SIR_TARGET_CARRY_SWITCH under the PcSwitch parameter of the RNC be turned on by using the SET UCORRMALGOSWITCH command and PERFENH_RL_RECFG_SIR_CONSIDER_SWITCH under the PerfEnhanceSwitch parameter of the RNC be turned on by using the SET UCORRMPAR command. Issue Draft A (2013-01-30)

9 Network Impact

9.3.2 Network Performance After the enhanced feature is introduced, more uplink power resources are saved.

9.4 WRFD-150230 DPCH Pilot Power Adjustment 9.4.1 System Capacity When the downlink load in a cell is heavy, this feature reduces downlink DPCH power consumption by configuring a shorter bit length and smaller power offset for the pilot field. Ultimately, this feature reduces the power requirements of each UE in this cell. If HSDPA UEs are in the majority in this cell, the mean transmit power of the downlink DPCH carrying HSDPA UEs is estimated to decrease by 5% to 20%. The saved power can admit 5% to 10% extra UEs if non-HSPA load remains unchanged. This capacity gain is affected by the proportion of UEs processing real-time services. The higher this proportion is, the less the gain this feature provides.

9.4.2 Network Performance Because the saved power can admit more UEs or increase the downlink throughput of a cell, this feature positively affects network performance as follows: 

When the number of UEs in a cell remains unchanged and the traffic volume in this cell is sufficient, more power will be saved to increase downlink cell throughput.



When potential UEs attempt to access a cell in the case of downlink power congestion, this feature increases the access success rate during busy hours.

This feature also has negative impact on network performance. If the power offset or bit length of the pilot field is reduced, SIR estimations will become less accurate and Uu-interface synchronization probability is reduced. This increases the call drop rate. Calls drops become more noticeable in lightly loaded cells.

9.5 WRFD-150235 DPCH Maximum Power Restriction 9.5.1 System Capacity When non-HSPA power consumption is high, this feature saves downlink power resources by reducing the maximum transmit power of the A-DPCH carrying HSDPA UEs. If the number of HSDPA UEs is large in a cell and downlink non-HSPA power is high, this feature reduces downlink non-HSPA power by 5% to 15%. The saved power can admit 5% to 15% extra UEs in this cell when non-HSPA power consumption in this cell remains unchanged.

9.5.2 Network Performance This feature positively affects network performance as follows: 

When the number of UEs in a cell remains unchanged and the traffic volume in this cell is sufficient, more power will be saved to increase downlink cell throughput.



When potential UEs attempt to access a cell in the case of downlink power congestion, this feature increases the access success rate during busy hours.

This feature also has negative impact on network performance. If the maximum transmit power of the A-DPCH is reduced, Uu-interface synchronization probability will decrease, which increases the call drop rate of HSDPA services. However, this feature causes call drops only for cell-edge HSDPA UEs. If a large number of HSPDA UEs camp on the cell edge, this feature saves more downlink power but triggers more call drops for these HSDPA UEs.

10.1.3 Activation 

Activate open loop power control on the downlink DPCH. This feature does not need to be activated on the downlink DPCH.



Activate open loop power control on the uplink DPCH.

This feature does not need to be activated on the uplink DPCH. Run the RNC MML command SET UFRC (CME single configuration: UMTS Radio Global Configuration Express > Basic Resource Control Parameter Configuration > RNC Oriented FRC Algorithm Parameters; CME batch modification center: Modifying RNC Parameters in Batches). In this step, set the parameters related to uplink DPCH power control. NOTE

The RNC uses the Default Constant Value parameter to calculate the power offset on the uplink DPCCH (DPCCH_Power_offset). Based on the calculation result, the UE calculates the initial transmit power on the uplink DPCCH (DPCCH_Initial_Power). The formula for calculating DPCCH_Power_offset is: DPCCH_Power_offset = Primary CPICH DL TX power + UL interference + Default Constant Value. Where, DPCCH_Power_offset indicates the initial transmit power offset on the DPCCH, Primary CPICH DL TX power indicates the downlink transmit power on the P-CPICH, UL interference indicates the uplink interference, and Default Constant Value is the value of Default Constant Value. The formula for calculating DPCCH_Initial_Power is: DPCCH_Initial_Power = DPCCH_Power_offset - CPICH_RSCP. Where, CPICH_RSCP indicates the received signal code power (RSCP) that the UE measures on the P-CPICH. An excessively small value of DPCCH_Power_offset may lead to uplink synchronization failures at the cell edge during initial link establishment, which affects uplink coverage. An excessively large value of DPCCH_Power_offset may lead to instantaneous interference on uplink signal reception, which affects the uplink receiving performance. For details, see 3GPP TS 25.331. 

Step 2 Establish a PS interactive BE service over HSUPA, for example, upload files to the FTP server.



10-14



NOTE

In multi-user scenarios where the target load is limited and the real-time rate of a single user is lower than a low-rate threshold (such as 60 kbit/s), the user is in the low-rate little retransmission state. The HARQ PO is the value of HARQ PO for small Retrans at Low Speed. If the real-time rate of a single user is higher than a high-rate threshold (such as 120 kbit/s), the user is in the high-rate little retransmission state. The HARQ PO is the value of HARQ PO for small Retrans at High Speed.

Step 3 Check the real-time rate of the new BE service and the CN-assigned rate by referring to Monitoring UL Throughput and Bandwidth, as shown in Figure 10-7. Figure 10-7 Rate of the new BE service

Step 4 Verification Procedure in the Scenario Where DCCC Takes Effect 1. Check the uplink throughput and bandwidth by referring to Monitoring UL Throughput and Bandwidth. The data rate of the HSUPA service when accessing the network is 256 kbit/s. Trace messages over the Uu interface by referring to Tracing Messages on the Uu Interface. The value of the HARQ PO in the RRC_RB_SETUP message shows that the user is in the high-rate little retransmission state. The HARQ PO is equal to the value of HARQ PO for small Retrans at High Speed, as shown in Figure 10-8.

2. After the file upload on the FTP is complete, check the uplink data rate of the UE by referring to Monitoring UL Throughput and Bandwidth. When the data rate is 608 kbit/s, check the value of HARQ PO in the RRC_RB_RECFG message by referring to Tracing Messages on the Uu Interface. The HARQ PO changes from HARQ PO for small Retrans at High Speed for 256 kbit/s to that for 608 kbit/s, as shown in Figure 10-9.

Step 5 Verification Procedure in the Scenario Where Dynamic CE Takes Effect



10-16



1. Trace messages over the Uu interface by referring to Tracing Messages on the Uu Interface. The value of the HARQ PO in the RRC_RB_SETUP message shows that the user is in the high-rate little retransmission state when accessing the network. The HARQ PO is equal to the value of HARQ PO for small Retrans at High Speed, as shown in Figure 10-10. Figure 10-10 HARQ PO (0) of a UE for little retransmission at a high speed

2. Simulate a situation that the uplink load is limited by changing the target uplink load to 10%. Run the RNC MML command MOD UCELLHSUPA. In this step, set Maximum Target Uplink Load Factor to 10. After the uplink load is limited, check the uplink throughput and bandwidth by referring to Monitoring UL Throughput and Bandwidth. HARQ PO reconfiguration is triggered when the uplink throughput of the UE is lower than the low-rate threshold. Check the value of HARQ PO in the RRC_RB_RECFG message by referring to Tracing Messages on the Uu Interface. The HARQ PO changes from HARQ PO for small Retrans at High Speed to HARQ PO for small Retrans at Low Speed, as shown in Figure 10-11.

If the feature WRFD-010641 HSUPA Adaptive Transmission takes effect, use another UE to perform a PS interactive service with an uplink rate of 2048 kbit/s and downlink rate of 7200 kbit/s in the cell. There is a possibility that the UE switches from little retransmission state to large retransmission state if the cell load increases to a certain value. Check the value of HARQ PO in the RRC_RB_RECFG message by referring to Tracing Messages on the Uu Interface.

the Maximum Bit Rate (MBR) of a typical RABINDEX is lower than 300 kbit/s, high-speed little retransmission will not occur. In this case, the HARQ PO of low-speed little retransmission should be set to 4.

− If

the MBR of a typical RABINDEX is higher than or equal to 300 kbit/s, the HARQ PO of low-speed little retransmission should be set to 4, and the HARQ PO of high-speed little retransmission should be set to 0. HARQ PO of large retransmission should be set to 0.

10.8.4 Performance Optimization Performance Monitoring The HSUPA throughput increases after this feature is enabled. The increase can be monitored by checking the RNC counters in Table 10-1. Table 10-1 Counters to monitor Counter

Description

VS.HSUPA.MeanChTh roughput.TotalBytes

Number of Total Bytes Received in Uplink of HSUPA MAC-d Flow for Cell

VS.HSUPA.MeanChTh roughput

Mean Uplink Throughput of single HSUPA MAC-d Flow for Cell

The RTWP of a cell may decrease after this feature is enabled. The decrease can be monitored by checking the RNC counter VS.MeanRTWP. However, the value of VS.MeanRTWP does not change noticeably if the RTWP decreases slightly, because VS.MeanRTWP indicates the mean RTWP over a time period. In this case, check the NodeB counters VS.HSUPA.LoadOutput.x (x ranges from 0 to 25), which measure the instantaneous change of the RTWP. Table 10-2 lists these counters.

VS.HSUPA.HARQ.POReCfgAtt.TTI10ms

Number of HARQ PO Reconfiguration Attempts of HSUPA Users with 10 ms TTI for Cell

After this feature is enabled, the system monitors the throughput and RTWP of cells based on VS.HSUPA.MeanChThroughput and VS.MeanRTWP. AS.HSUPA.MeanChThroughput, which indicates the mean throughput in a cell, increases after this feature is enabled. VS.MeanRTWP, which indicates the mean RTWP in a cell, may decrease after this feature is enabled. When a large number of UEs are processing services, only GBRs are provided for most UEs. In this case, this feature does not increase throughput notably but reduces the uplink RTWP. The system monitors whether this feature takes effect and measures the number of successful HARQ PO reconfigurations based on the counters VS.HSUPA.HARQ.POReCfgSucc.TTI10ms and VS.HSUPA.HARQ.POReCfgAtt.TTI10ms. VS.HSUPA.HARQ.POReCfgSucc.TTI10ms indicates the number of successful HARQ PO reconfigurations of HSUPA 10 ms TTI UEs in a cell. VS.HSUPA.HARQ.POReCfgAtt.TTI10ms indicates the number of HARQ PO reconfiguration attempts of HSUPA 10 ms TTI UEs in a cell.

10.8.7 Dependencies on HSUPA Adaptive Transmission This feature is independent of the feature HSUPA Adaptive Transmission. Enabling this feature does not affect the gain from using HSUPA Adaptive Transmission. Deployment scenarios for this feature are complementary to those for HSUPA Adaptive Transmission. For example, HSUPA Adaptive Transmission takes effect for upload services but not for download services of HSUPA 10 ms TTI UEs. This feature, however, can take effect for downloading services because only TCP and RLC ACK/NACK are sent in the uplink. Download services have low uplink data rates. This is an appropriate deployment scenario of this feature. Using HSUPA Adaptive Transmission requires extra CEs and therefore does not bring considerable gains if CEs are insufficient. This feature, however, increases cell throughput by reducing the transmit power on the DPCCH even when CEs are insufficient.

10.9 WRFD-020138 HSUPA Coverage Enhancement at UE Power Limitation 10.9.1 When to Use HSUPA Coverage Enhancement at UE Power Limitation This feature is recommended if the following conditions are met: 

HSUPA UEs are using a 2 ms or 10 ms TTI.



The transmit power of the UEs is limited because the cell is experiencing deep fading or the coverage performance at the cell edge is poor.

10.9.2 Required Information None

10.9.3 Planning None



10-22




Dependencies on Hardware There is no requirement for RNC or NodeB. The UE needs to support 3GPP Release 8 or later. It also needs to support improved EUL power control at UE power limitation.






License The license "HSUPA Coverage Enhancement at UE power limitation" on the RNC side has been activated. For details about the license items and how to activate the license, see License Management Feature Parameter Description.

Data Preparation None

Activation Step 1 Run the RNC MML command SET UCORRMALGOSWITCH (CME single configuration: UMTS Radio Global Configuration Express > Connection_Oriented RRM Switch Configuration > Connection Oriented Algorithm Switches; CME batch modification center: Modifying RNC Parameters in Batches) to select PC_HSUPA_COVER_EN_AT_POLIMIT_SWITCH under the Power Control Switch parameter to activate the feature. Step 2 Run the RNC MML command MOD UTYPRABHSUPAPC (CME single configuration: UMTS Radio Global Configuration Express > Typical Service Configuration > Typical RAB HSUPA Power Control Parameters; CME batch modification center: not supported) to set Minimum Reduced E-DPDCH Gain Factor. ----End

Activation Observation Start Uu Interface Trace on the LMT to trace messages on the Uu interface. View the RRC_RB_SETUP message, as shown in Figure 10-13. If the e-DPDCH-info message contains the minReduced-E-DPDCH-GainFactor information element (IE), it indicates that this feature takes effect, and the RNC sends the UE the transmit power of the data channel.

//Deactivation procedure //Deactivating the feature SET UCORRMALGOSWITCH: PcSwitch=PC_HSUPA_COVER_EN_AT_POLIMIT_SWITCH-0;

10.9.5 Performance Optimization Performance Monitoring This feature provides a gain for HSUPA UEs at the cell edge. The gain is indicated by the decreased call drop rate of HSUPA services when there are many users at the cell edge.

Parameter Optimization Different values of the BetaEdMin parameter lead to different uplink coverage performance. The uplink coverage performance is indicated by the call drop rate of HSUPA services. If the call drop rate does not decrease after this feature is enabled and BetaEdMin is set to the recommended value, fine-tune the parameter value to achieve the best result.

10.10 Outer Loop Power Control Enhancement 10.10.1 When to Use Outer Loop Power Control Enhancement The enhanced feature applies to all UMTS networks. It is recommended that the enhanced feature be used in scenarios where services are frequently established and service duration is short.

10.10.2 Deployment For details about how to activate, verify, and deactivate this feature, see 10.3 "WRFD-020503 Outer Loop Power Control."

10.10.3 Parameter Settings Parameters related to the enhanced feature are described as follows: 

SIRtargetDownSpeed specifies the SIRtarget quick decrease step. The default value is 10, indicating that the SIRtarget quick decrease step is 1 dB/s. A larger value of SIRtargetDownSpeed introduces higher amplitude of the SIRtarget quick decrease, but may increase the block error rate. A smaller value of SIRtargetDownSpeed introduces lower amplitude of the SIRtarget quick decrease, but increases only a limited amount of uplink capacity.



RefSIRtarget is the convergence value of the SIRtarget when RB establishment or reconfiguration is complete. RefSIRTarget is set according the service rate. The difference between InitSirtarget and RefSIRtarget is the maximum range of the SIRtarget quick decrease. Therefore, the value of RefSIRtarget must be equal to or smaller than the value of InitSirtarget. Otherwise, the SIRtarget quick decrease cannot be enabled. A larger value of RefSIRTarget introduces smaller amplitude of the SIRtarget quick decrease, but increases only a limited amount of uplink capacity. A smaller value of RefSIRTarget introduces larger amplitude of the SIRtarget quick decrease, but may increase the block error rate.

10.11 WRFD-150230 DPCH Pilot Power Adjustment 10.11.1 When to Use DPCH Pilot Power Adjustment This feature is used in areas with high non-HSDPA transmit power and a small number of UEs processing conversational services (including emergency calls) or streaming services, such as hot spots in cities.

10.11.2 Required Information Before activating this feature, collect the following information to evaluate whether this feature is suitable for the live network. 

Values of the VS.MeanTCP.NonHS counter and the MAXTXPOWER parameter The proportion of non-HSDPA transmit power in a cell can be estimated based on the value of (Vs.MeanTCP.NonHS – MAXTXPOWER/10). If the result is –3 dB, non-HSPPA transmit power in this cell is high.



Value of the VS.CellDCHUEs counter and the number of UEs processing real-time services The proportion of UEs processing real-time services can be estimated based on the value of (Number of UEs processing real-time services/VS.CellDCHUEs). If the result is smaller than 10%, the proportion of UEs processing real-time services is small. UEs processing real-time services are those that process CS or streaming services. Real-time services include AMR voice services and PS conversational services. The following is the formula for calculating the number of UEs processing real-time services: Number of UEs processing real-time services = VS.RB.AMR.DL.12.2 + VS.RB.AMR.DL.10.2 + VS.RB.AMR.DL.7.95 + VS.RB.AMR.DL.7.4 + VS.RB.AMR.DL.6.7 + VS.RB.AMR.DL.5.9 + VS.RB.AMR.DL.5.15 + VS.RB.AMR.DL.4.75 + VS.RB.PS.Conv.HSDSCH

Power Control Switch

PcSwitch: PC_PILOT_PO_OP TI_SWITCH

This switch is a pilot power offset optimization switch: It is recommended that this feature be activated if the current scenario for activating this feature meets the requirements in section 10.11.1 "When to Use DPCH Pilot Power Adjustment."

Default/Recomm ended value

Non-CS Pilot Power Offset Optimization

NonCsOptiPilotPo

If this parameter is set to a large value, Default/Recomm the downlink DPCH power of non-CS UEs ended value will be high and the downlink capacity gains in the cell will be reduced. If this parameter is set to a small value, the downlink DPCH power of non-CS UEs will be low. However, the probability of incorrect SIR estimations will increase.

CS Pilot Power Offset Optimization

If this parameter is set to a large value, Default/Recomm the downlink DPCH power of CS UEs will ended value be high and the downlink capacity gains in the cell will be reduced.

CsOptiPilotPo

If this parameter is set to a small value, the downlink DPCH power of CS UEs is smaller. However, the probability of incorrect SIR estimations will increase. Downlink DlDpchSf256OptiPi None DPCH Pilot Bit lotBit Num Optimization


Load State For Pilot Power Adjust


LoadStateForPilot PwrAdj

If this parameter is set to a large value, the DPCH Pilot Power Adjustment feature will be more difficult to trigger. As a result, power load on the downlink DPCH cannot be effectively reduced. If this parameter is set to a small value, the PCH Pilot Power Adjustment feature will be more easily triggered. This increases the call drop rate when the power load of the downlink DPCH is light. It is recommended that this parameter be set to a value equal to or larger than DL_LOADED_STATE.

Activation (Using MML Commands) Step 1 (Optional) Adjust the corresponding parameters in the existing network before activating this feature.



10-34



1. Run the RNC MML command SET UFRC to configure the optimized pilot power offset and bit length. In this step, set the Non-CS Pilot Power Offset Optimization, CS Pilot Power Offset Optimization, and Downlink DPCH Pilot Bit Num Optimization parameters to appropriate values. 2. Run the RNC MML command SET UFRC and set the Load State For Pilot Power Adjust parameter. 3. Set the Load State For Pilot Power Adjust parameter to an appropriate value for a cell. 

For initial configuration, run the RNC MML command ADD UCELLFRC and set the Load State For Pilot Power Adjust parameter.



For reconfiguration, run the RNC MML command MOD UCELLFRC and set the Load State For Pilot Power Adjust parameter. NOTE

If one parameter is set both at the RNC level and at the cell level, the cell-level setting takes precedence.

Step 2 Run the RNC MML command SET UCORRMALGOSWITCH and select PC_PILOT_PO_OPTI_SWITCH under the Power Control Switch parameter. ----End

MML Command Examples //Activating the DPCH Pilot Power Adjustment feature SET UFRC:NonCsOptiPilotPo=0,CsOptiPilotPo=12,DlDpchSf256OptiPilotBit=D2; SET UFRC:LoadStateForPilotPwrAdj=DL_LOADED_STATE; SET UCORRMALGOSWITCH:PcSwitch= PC_PILOT_PO_OPTI_SWITCH-1;

Activation Observation There are three methods of checking whether this feature is activated: 

Method one Check counters related to this feature. If the value of VS.DL.DPCH.OptiPilotPOAttNum is not 0, this feature is activated.



Method two Check signaling messages transmitted on the Uu interface. For HSDPA UEs, check the "Power offset Pilot-DPDCH" of the "Downlink DPCH info common for all RL" IE in the RB setup message. IE is short for information element. If the value of "Power offset Pilot-DPDCH" is the optimized pilot power (including the value of the Non-CS Pilot Power Offset Optimization or CS Pilot Power Offset Optimization parameter), this feature is activated.

Figure 10-14 RB setup message

The value of "Power offset Pilot-DPDCH" has the same meaning as the value of the Non-CS Pilot Power Offset Optimization or CS Pilot Power Offset Optimization parameter. 

Method three Check signaling messages transmitted on the Uu interface. For UEs processing only HSDPA services not R99 services, check the "Number of bits for Pilot bits" (pb for short) IE in the RB setup message. If the value of this IE is the value of the Downlink DPCH Pilot Bit Num Optimization parameter, this feature is activated.

10.11.5 Performance Monitoring Collect the average downlink non-HSPA transmit power in a cell and the number of UEs in the CELL_DCH state. Then calculate the non-HSPA transmit power of each UE in a cell.



10-37



After this feature is activated, the non-HSPA transmit power of each UE in a cell is reduced. This feature increases the call drop rate in lightly loaded cells. You can monitor call drop rate-related counters to observe the impact of this feature. Call drop rate-related counters include the CS call drop rate and PS service drop rate. Table 10-9 provides counters and KPIs to monitor and how to calculate the mean transmit power of each non-HSPA UE in the cell. Table 10-9 Counters and KPIs to monitor Counters and KPIs

Description

VS.MeanTCP.NonHS/VS.CellDC HUEs

This counter indicates the R99 transmit power of each UE in a cell. This counter measures the gains of this feature. After this feature is activated, the mean transmit power of each R99 UE in a cell decreases.

AMR Call Drop Ratio

This KPI indicates the CS call drop rate. This KPI measures the impact of this feature. After this feature is activated, the CS call drop rate decreases.

PS Service Drop Ratio (Cell)

This KPI indicates the PS service drop rate. This KPI measures the impact of this feature. After this feature is activated, the PS service drop rate decreases.

PS Service Drop Ratio (RNC) VS.DL.DPCH.OptiPilotPOAttNum VS.DL.DPCH.NormalPilotPOAttN um

The two counters measure whether this feature takes effect and they are added due to the introduction of this feature. The value of the VS.DL.DPCH.OptiPilotPOAttNum counter indicates the number of attempts to configure pilot-filed power offset according to the value of the CsOptiPilotPo or NonCsOptiPilotPo parameter. If the value of this counter is not 0, this feature takes effect. The activation rate of this feature can be evaluated based on: VS.DL.DPCH.OptiPilotPOAttNum/(VS.DL.DPCH.OptiPilotPOAtt Num + VS.DL.DPCH.NormalPilotPOAttNum)

RRC Setup Success Ratio CS RAB Setup Success Ratio PS RAB Setup Success Ratio

These KPIs measure the impact of this feature on the cell access success rate. Downlink power resource congestion in a cell may lead to UE admission failures. The activation of this feature alleviates downlink power resource congestion in a cell and increases the cell access success rate. Monitor the three KPIs to determine whether the cell access success rate increases. After this feature is activated, the cell access success rate increases.

Mean Throughput for One HSDPA These KPIs measure the impact of this feature on service Cell integrity. VS.HSDPA.MeanChThroughput


When the number of UEs in a cell remains unchanged, the saved downlink power can increase cell HSDPA throughput and single-UE HSDPA throughput if the traffic volume in this cell is sufficient. Monitor the Mean Throughput for One HSDPA Cell KPI to determine cell HSDPA throughput and monitor the VS.HSDPA.MeanChThroughput counter to determine single-UE HSDPA throughput. After this feature is activated, cell HSDPA throughput and single-UE HSDPA throughput increase.


10-38



The gains provided by this feature may vary according to the fluctuations of one sample. In this case, you can use the preceding counters to draw a graph that shows the distribution of the mean non-HSDPA downlink transmit power relative to different CELL_DCH UE numbers, as shown in Figure 10-16. The blue line and the red line indicate the distributions without and with this feature, respectively. The difference between the two lines is the gain provided by this feature. Figure 10-16 Distributions of downlink transmit power of non-HSDPA UEs relative to different CELL_DCH UEs numbers with and without this feature

10.11.6 Parameter Optimization If this feature does not provide noticeable gains, you can set the LoadStateForPilotPwrAdj parameter to a value with lighter load so that this feature can be more easily triggered, for example, DL_NORMAL_STATE. If the call drop rate increase noticeably after this feature is activated, for example, 50%, you can set the LoadStateForPilotPwrAdj parameter to a value with heavier load so that this feature is more difficult to trigger, for example, DL_HEAVY_STATE or set DlDpchSf256OptiPilotBit to 4. Check the gains and the call drop rate each time after you optimize the preceding parameters to determine whether the gains and the call drop rate reach the expected level.


10.12 WRFD-150235 DPCH Maximum Power Restriction 10.12.1 When to Use DPCH Maximum Power Restriction This feature is used in cells with a large number of HSDPA UEs and high downlink non-HSPA power consumption, such as hot spots in cities.



10-39



10.12.2 Required Information Before activating this feature, collect the following information to evaluate whether this feature is suitable for the live network. 

Average number of HSDPA UEs in a cell The average number of HSDPA UEs in a cell is indicated by the RNC counter VS.HSDPA.UE.Mean.Cell. The gain provided by this feature is noticeable only when there is a large number of HSDPA UEs in this cell.



Non-HSPA power consumption in a cell Non-HSPA power consumption in a cell is indicated by the RNC counter VS.MeanTCP.NonHS. This feature reduces the maximum transmit power of the A-DPCH only when the downlink non-HSPA power consumption in the cell is high. Non-HSPA power consumption can be estimated based on the linear value of (VS.MeanTCP.NonHS – MaxTxPower/10). If the proportion is high, downlink Non-HSPA power consumption in this cell is high.

VS.CellDCHUEs

Number of UEs access a cell

This feature saves downlink power. If potential UEs attempt to access a cell, the saved power can admit more UEs if the traffic volume in this cell remains unchanged. Monitor the VS.CellDCHUEs counter to observer whether the number of UEs camping on this cell increases. After this feature is activated, the number UEs access this cell increases.

RRC Setup Success Ratio

Cell access success rate

Downlink power resource congestion in a cell may lead to cell access failures. The activation of this feature alleviates downlink power resource congestion in a cell and increases the cell access success rate. Monitor the three KPIs to determine whether the cell access success rate increases. After this feature is activated, the cell access success rate increases.

Cell HSDPA throughput and single-UE HSDPA throughput

When the number of UEs in a cell remains unchanged, the saved downlink power can increase cell HSDPA throughput and single-UE HSDPA throughput if the traffic volume in this cell is sufficient. Monitor Mean Throughput for One HSDPA Cell to determine cell HSDPA throughput and monitor the VS.HSDPA.MeanChThroughput counter to determine single-UE HSDPA throughput. After this feature is activated, cell HSDPA throughput and single-UE HSDPA throughput increase.

Call drop rate of HSDPA services

This feature reduces the maximum transmit power of the A-DPCH, which may reduce Uu-interface synchronization probability and increase the call drop rate of HSDPA services. Monitor HSDPA Call Drop Ratio to observe whether the call drop rate of HSDPA services increases. After this feature is activated, the call drop rate of HSDPA services may increase.

10.12.6 Parameter Optimization After this feature is activated, if the impact of this feature on HSDPA service drop rates and on non-HSPA power consumption is not noticeable, you can set the dpchMaxPwrRtrLoadStat parameter to a value with lighter load (such as DlNormalState)so that this feature can be more easily triggered. This helps save the downlink power and the saved power can admit more UEs or increase cell HSDPA throughput.

If HSDPA service drop rates increase noticeably, you can set the dpchMaxPwrRtrLoadStat parameter to a value with heavier load (such as DlHeavyState) so that this feature is more difficult to trigger. This helps prevent noticeable impact of this feature on network KPIs.

DefaultC BSC69 SET onstantV 00/BS UFRC alue C6910

WRFD-02 Open Loop Meaning:Constant that is used by the RNC to 0501 Power Control calculate the DPCCH_Power_Offset which is further used by the UE to calculate the UL DPCCH_Initial_Power. The formulas are as follows: DPCCH_Power_Offset = Primary CPICH DL TX power + UL interference + Default Constant Value Here, DPCCH_Power_Offset is the DPCCH initial transmit (TX) power offset, Primary CPICH DL TX power is the downlink TX power of the P-CPICH. DPCCH_Initial_Power = DPCCH_Power_offset CPICH_RSCP Here, CPICH_RSCP is the received signal code power of the P-CPICH measured by the UE. A small value of DPCCH_Power_Offset might lead to uplink synchronization failure at cell edges during link setup, thus affecting the uplink coverage. A large value of DPCCH_Power_Offset, however, has instantaneous interference on uplink reception, thus affecting the uplink reception performance. For details, see 3GPP TS 25.331.

DlHeavyState: indicates the downlink resource severe congestion state threshold ranging from 70% to 94%. DlOverloadState: indicates the downlink resource extreme congestion state threshold ranging from 95% to 100%. The following provides the method for determining the downlink non-HSPA power load state: If the non-HSPA power load for a cell exceeds the threshold corresponding to the load state when the maximum DPCH power restriction algorithm takes effect plus 10%, the NodeB determines that the downlink non-HSPA power load for the cell is in the load state set when this algorithm takes effect or a higher load state. In this case, the maximum DPCH power restriction algorithm is triggered. Note that 10% is not added when the downlink non-HSPA power load is in the downlink resource extreme congestion state. If the non-HSPA power load for a cell decreases below the threshold corresponding to the load state when the maximum DPCH power restriction algorithm takes effect minus 10%, the NodeB determines that the downlink non-HSPA power load for the cell is in the load state set when this algorithm takes effect or a lower load state. In this case, the maximum DPCH power restriction algorithm is not triggered. Note that 10% is not subtracted when the downlink non-HSPA power load is in the downlink resource light load state.

The function controlled by this switch also takes effect during an RAB setup process. When this switch is turned off, the power offset is determined by the algorithm controlled by the PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_S WITCH. If the PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_S WITCH is turned off, the power offset is 0. 22. PC_PILOT_PO_OPTI_SWITCH: Sets small pilot power offset and small number of bits for pilot bits in case of downlink cell power congestions to decrease power congestions. When this switch is turned on and the cell downlink non-HSPA power is exceeds the value of "DLNoHSPAThd"("ADD UCELLLDM"), the power offset configured in the pilot domain on the DL DPCH is "NonCsOptiPilotPo"("SET UFRC") or "CsOptiPilotPo"("SET UFRC"). When the spreading factor (SF) is 256, the number for bits of pilot bits of the DPCH is "DlDpchSf256OptiPilotBit"("SET UFRC"). Regardless of the switch state, if the downlink non-HSPA power for the cell is smaller than or equals to the threshold for the downlink non-HSPA power, the pilot power offset for the DPCH is "PilotPo"("SET UFRC"). If the SF is 256, the number for bits of pilot bits over the DPCH is "DlDpchSf256PilotBit"("SET UFRC").

The value of this IE can be changed by running the "SET UUESTATETRANS" command. 17. PERFENH_CELL_HSUPA_CAP_CHANGE_OPT _SWITCH: The NodeB baseband board uses different processing specifications for users with different uplink bearer services, for example, HSUPA TTI 2 ms services, HSUPA TTI 10 ms services, and R99 services. When serving a large number of users, the system cannot guarantee that all users can access the network with the highest service bearer supported by UEs. This switch controls whether the RNC allocates corresponding channels for new users based on the cell capability reported through the NodeB private interface. When this switch is turned on, the RNC dynamically selects an appropriate uplink service bearer and allocates corresponding channels for new users to maximize the system capacity based on the actual NodeB processing specifications. When this switch is turned off, the optimization process is disabled. 18. PERFENH_HSUPA_TTI_RECFG_PROC_OPT_S WITCH: Whether to use the optimized TTI switching algorithm for BE services When this switch is turned off, the optimized algorithm does not take effect.
