Overview

2.1 Introduction As mobile communication services continue to develop, users have increasingly high requirements for downlink throughput. Multi-carrier HSDPA technologies enable UEs to set up HSDPA connections with multiple carriers, which increases the single-user downlink throughput. Before the Flexible Dual Carrier HSDPA feature was introduced, carriers that meet certain requirements could only form DC-HSDPA groups, and one carrier could belong to only one group. Therefore, multi-carrier HSDPA technologies could not be flexibly applied, and frequency resources were not fully utilized. NOTE

l SC-HSDPA is short for Single-Carrier High Speed Downlink Packet Access. l DC-HSDPA is short for Dual-Carrier High Speed Downlink Packet Access.

Now, with introduction of the Flexible Dual Carrier HSDPA feature, inter-frequency cocoverage cells that meet certain requirements can form a multi-carrier cell group, and cells in the multi-carrier cell group work in resource pool mode. The RNC dynamically selects cells from the group based on HSPA+ technical satisfaction, service requirements, and network load to construct DC-HSDPA groups for different UEs to fulfill their service requirements. Figure 2-1 shows an example of cell group configuration with and without Flexible Dual Carrier HSDPA. Figure 2-1 Example of cell group configuration with and without the Flexible Dual Carrier HSDPA feature

2 Overview

Figure 2-1 assumes that an operator has three inter-frequency co-coverage cells: F1, F2, and F3. Before the Flexible Dual Carrier HSDPA feature was deployed, two cells F1 and F2 formed one DC-HSDPA group and the third cell F3 worked as an SC-HSDPA cell. With the Flexible Dual Carrier HSDPA feature, the three cells F1, F2, and F3 can form a multi-carrier cell group, and cells in the multi-carrier cell group can flexibly form three DC-HSDPA groups for the HSDPA transmission of different UEs.

2.2 Benefits The Flexible Dual Carrier HSDPA feature dynamically uses instantaneous idle resources in a cell, increasing the UE data rate and system capacity. In the case of three carriers, this feature increases the UE data rate by up to 20% when UEs are processing burst services. The feature gain is affected by the proportion of UEs supporting the multi-carrier HSDPA technologies. This feature enables a smooth evolution between multi-carrier HSDPA technologies by configuring multi-carrier cell groups.

2.3 Feature Capabilities 2.3.1 Multi-Carrier HSDPA Technologies The Flexible Dual Carrier HSDPA feature supports the following multi-carrier HSDPA technology: DC-HSDPA and DC-HSDPA+MIMO

NOTICE If the Flexible Dual Carrier HSDPA feature is used with the WRFD-010684 2×2 MIMO feature, the Primary/Secondary common Pilot (PSP) mode must be used. For details, see MIMO Feature Parameter Description. The Flexible Dual Carrier HSDPA feature flexibly allocates different DC-HSDPA groups to different UEs. NOTE

For details about how to enable the DC-HSDPA feature, see DC-HSDPA Feature Parameter Description.

Figure 2-2 shows an example of using the Flexible Dual Carrier HSDPA feature and multicarrier HSDPA technology together.

Figure 2-2 Example of using the Flexible Dual Carrier HSDPA feature and multi-carrier HSDPA technology together

2.3.2 Cells Candidate for a Multi-Carrier Cell Group This section describes the requirements for cells to become candidates for a multi-carrier cell group.

Coverage Cells in a multi-carrier cell group must belong to the same sector of a NodeB and must be interfrequency co-coverage cells. Each multi-carrier cell group must have three or four interfrequency cells. For DBS3800 and DBS3900 series base stations, cells in a multi-carrier cell group must be served by the same BBU.

Frequency Bands, Frequencies, and Bandwidth l

A multi-carrier cell group consists of a maximum of four cells. The cells in a multi-carrier cell group must operate in the same frequency band.

l

Cells in the same frequency band can use adjacent frequencies or non-adjacent frequencies. NOTE

When cells in the same frequency band use non-adjacent frequencies, UEs must support non-adjacent frequencies.

Cell HSPA+ Capability l

2 Overview

l

In a multi-carrier cell group, cells in the same frequency band must have either the WRFD-010696 DC-HSDPA or WRFD-010699 DC-HSDPA+MIMO feature enabled.

l

One cell can belong to only one multi-carrier cell group.

l

Cells in a multi-carrier cell group have the same time offset (specified by the Tcell (BSC6900,BSC6910) parameter).

Others

NOTE

Tcell(BSC6900,BSC6910) specifies the difference between the System Frame Number (SFN) and NodeB Frame Number (BFN) of the NodeB that the cells belong to. Tcell(BSC6900,BSC6910) is set in the MOD UCELLSETUP command.

2.3.3 Configuration of Multi-Carrier Cell Groups To configure a multi-carrier cell group, perform the following steps: Step 1 Run the NodeB MML command ADD NODEBMULTICELLGRP to add a multi-carrier cell group. In this step, specify MULTICELLGRPID and set MULTICELLGRPTYPE to HSDPA. Step 2 Run the NodeB MML command ADD NODEBMULTICELLGRPITEM multiple times to add local cells to the multi-carrier cell group. ----End

NOTICE Before you configure a multi-carrier cell group, for example, if you want to add a cell to or remove a cell from the group, you need to deactivate all cells in the group first. Deactivating a cell interrupts services in the cell. Therefore, configure a multi-carrier cell group during off-peak hours, for example, in the early morning.

3.1 Overview This section describes the impacts of Flexible Dual Carrier HSDPA on protocol entities, requirements for network elements (NEs), and impacts on radio resource management (RRM) functions.

3.1.1 Impacts on Protocol Entities Figure 3-1 shows the protocol entities affected by the Flexible Dual Carrier HSDPA feature. Figure 3-1 Protocol entities affected by the Flexible Dual Carrier HSDPA feature

The Flexible Dual Carrier HSDPA feature affects the NodeB application part (NBAP) entity on the control plane and the MAC-ehs entity on the user plane as follows: l

NBAP entity – Cell capability reporting: The NodeB reports the list of candidate secondary cells to the RNC. – Radio link (RL) setup and reconfiguration: The RNC sends information about primary and secondary cells to the NodeB.

l

MAC-ehs entity The Flexible Dual Carrier HSDPA feature affects the scheduling function of the MAC-ehs entity.

Each UE is assigned a MAC-ehs entity. Before the Flexible Dual Carrier HSDPA feature is introduced, the MAC-ehs entity assigned to a DC-HSDPA UE performs joint scheduling between the primary and secondary cells. After the Flexible Dual Carrier HSDPA feature is introduced, the NodeB supports joint scheduling for all DC-HSDPA UEs in different cells.

3.1.2 Requirements for NEs Table 3-1 describes the requirements of the Flexible Dual Carrier HSDPA feature for NEs. Issue 03 (2014-03-31)

CN

None

RNC

The RNC must select the primary and secondary cells for UEs based on the information about candidate secondary cells reported by the NodeB. The RNC also performs multi-carrier HSDPA load control and scheduling. For details, see sections 3.2 Load Control and 3.4 Multi-Carrier HSDPA Scheduling.

NodeB

l The NodeB must determine the list of candidate secondary cells for each cell based on the configured multi-carrier cell groups and report the primary and secondary cell information to the NodeB over the Iub interface. l The NodeB must perform joint scheduling between the primary and secondary cells for a single UE.

UE

UEs must support at least one multi-carrier HSDPA technology and must belong to HS-DSCH category 21 or higher.

The Flexible Dual Carrier HSDPA feature requires support from NEs. Details are as follows: The NodeB reports the multi-carrier HSDPA capability of each cell and the list of candidate secondary cells for each cell over the Iub interface. l

The RNC determines the multi-carrier HSDPA capability of a UE based on the information reported by the UE.

l

The RNC selects a radio bearer and appropriate primary and secondary cells for the UE. The RNC then sends the bearing information to the NodeB and UE.

l

After the radio bearer is set up, the NodeB performs joint scheduling for the UE between the primary and secondary cells.

3.1.3 Impacts on RRM Functions Table 3-2 describes the impacts on RRM functions: radio bearer, load control, dynamic cell shutdown, scheduling, and secondary carrier activation/deactivation. Table 3-2 Impacts on RRM functions

N/A

3.2 Load Control 3.2.1 Load Measurement The Flexible Dual Carrier HSDPA feature affects the cell load estimation in the following aspects: l

Downlink cell power – Cell Guaranteed Bit rate Power (GBP), which is used for downlink power admission algorithms 1 and 3 – Equivalent number of downlink users, which is used for downlink power admission algorithm 2

l

Number of HSDPA users

For details about load estimation, see Call Admission Control Feature Parameter Description. The load estimation results serve as a basis for Potential User Control (PUC), LDR, OLC, and load balancing-based inter-frequency DRD. Of these functions, only the PUC remains unchanged after the Flexible Dual Carrier HSDPA feature is applied.

Cell Downlink GBP When the Flexible Dual Carrier HSDPA feature is applied, the cell downlink GBP consists of R99 user power, SC-HSDPA user power, and DC-HSDPA user power. The transmit power of each DC-HSDPA user in the primary or secondary cell equals the user's total GBP multiplied by the percentage of the transmit power in the cell. NOTE

GBP is the power required for the guaranteed bit rate (GBR) in the downlink.

Figure 3-2 shows the composition of cell downlink GBP after the Flexible Dual Carrier HSDPA feature is applied. Issue 03 (2014-03-31)


10



Figure 3-2 Composition of cell downlink GBP after the Flexible Dual Carrier HSDPA feature is applied

NOTE

The methods of estimating the downlink cell power in a DC-HSDPA cell are the same before and after the Flexible Dual Carrier HSDPA feature is enabled. For details, see Call Admission Control Feature Parameter Description.

Equivalent Number of Downlink Users When the Flexible Dual Carrier HSDPA feature is activated, DC-HSDPA users consume ENU resources only in the primary cell. For details about how to calculate the consumed ENU resources in a cell, see Call Admission Control Feature Parameter Description. NOTE

ENU is short for equivalent number of users.

Number of HSDPA Users The Flexible Dual Carrier HSDPA feature does not affect the estimation of the number of HSDPA users. One DC-HSDPA user is calculated as one HSDPA user only in the primary cell.

3.2.2 DRD This section describes only the DRD when the Flexible Dual Carrier HSDPA feature is applied. For details about DRD, see Directed Retry Decision Feature Parameter Description. For details about the DRD for DC-HSDPA UEs, see DC-HSDPA Feature Parameter Description. During the radio bearer setup or state transition from CELL_FACH, CELL_PCH, or URA_PCH to CELL_DCH, the RNC performs DRDs to select primary and secondary cells for UEs if the RNC determines that DC-HSDPA is configured for the UEs according to the radio bearer policy. The DRD procedure is as follows: Issue 03 (2014-03-31)


11


1.


The RNC ranks candidate cells that meet the DRD quality requirements. The Flexible Dual Carrier HSDPA feature does not affect candidate cell ranking. During candidate cell ranking, the RNC successively performs DRD for device type steering, DRD for HSPA+ technical satisfaction, DRD for service priority, DRD for load balancing, and DRD for user position. For details, see DC-HSDPA Feature Parameter Description.

2.

The RNC determines primary and secondary cells. The RNC selects the primary cell in order from high priority to low priority ranked in the preceding step. After selecting the primary cell, the RNC selects a secondary cell in order from light downlink load to heavy downlink load from the candidate secondary cell list to form a cell group with the primary cell and then performs CAC. The candidate secondary cell list is reported by the NodeB to the RNC for each primary cell. If the CAC attempt succeeds, the UE is served by the selected cell group. If the CAC attempt fails, the RNC selects the next secondary cell in order of load from the candidate secondary cell list. If the CAC attempt fails in all candidate secondary cells, the RNC selects the next primary cell in order of priority and performs CAC. The RNC repeats this process until the CAC procedure is successful. NOTE

The primary and secondary cells for a DC-HSDPA user must belong to the same multi-carrier cell group.

A primary cell can have multiple candidate secondary cells. Assume that a multi-carrier cell group has three cells that operate in three adjacent frequencies in the same band: F1, F2, and F3. If the RNC selects F2 as the primary cell for a DC-HSDPA UE, F1 and F3 are both candidate secondary cells. Therefore, F2 can form a DC-HSDPA group with either of them. The SecCellLdbDrdChoice(BSC6900,BSC6910) parameter specifies the downlink load type during secondary cell selection. l

When this parameter is set to UserNumber, the RNC selects a secondary cell based on the number of HSDPA users.

l

When this parameter is set to Power, the RNC selects a secondary cell based on the downlink power.

The SecCellLdbDrdChoice(BSC6900,BSC6910) parameter can be set at either the RNC level or the cell level. The RNC-level parameter is in the SET UDRD command. The cell-level parameter is in the ADD UCELLDRD or MOD UCELLDRD command. If this parameter is set at the cell level, the cell-level parameter prevails, regardless of whether it is also set at the RNC level. If this parameter is set only at the RNC level, the RNC-level parameter prevails.

3.2.3 CAC The Flexible Dual Carrier HSDPA feature affects only downlink cell power resource-based CAC. For details about CAC, see Call Admission Control Feature Parameter Description. For details about the CAC for DC-HSDPA UEs, see DC-HSDPA Feature Parameter Description..

DC-HSDPA cell

l For non-DC-HSDPA UEs, the RNC performs CAC in the serving cell and in the DCHSDPA group.

For DC-HSDPA UEs, the RNC performs CAC based on the remaining downlink power of the DCHSDPA group.

l For DC-HSDPA UEs, the RNC performs CAC based on the remaining downlink power of the DC-HSDPA group. Yes

DC-HSDPA cell

For DC-HSDPA UEs, the RNC performs CAC in the primary and secondary cells. If the CAC procedure in any cell is successful, the admission of DC-HSDPA UEs is considered successful.

For DC-HSDPA UEs, the RNC performs CAC only in the primary cell.

CAC based on Other Resources The Flexible Dual Carrier HSDPA feature does not affect CAC based on the number of HSDPA users. For DC-HSDPA UEs, the RNC performs CAC based on the number of HSDPA users only in the primary cell. The Flexible Dual Carrier HSDPA feature does not affect NodeB credit resource-based CAC and Iub resource-based CAC.

Admission Failure Processing Figure 3-3 shows how a DC-HSDPA UE admission failure is processed.

Issue 03 (2014-03-31)


13



Figure 3-3 Admission failure processing

The RNC attempts to select a neighboring cell for inter-frequency blind handovers as the primary cell and then selects an appropriate secondary cell. The RNC then performs CAC. If the CAC attempt fails in all inter-frequency co-coverage cells in the same sector, DC-HSDPA services fall back to R99 channels in the current cell and then reattempt to access the network.

3.2.4 Queuing and Preemption The Flexible Dual Carrier HSDPA feature does not affect the queuing and preemption functions of DC-HSDPA UEs. l

DC-HSDPA UEs are queued only in the primary cell.

l

DC-HSDPA UEs preempt only the resources of other DC-HSDPA UEs in the primary cell.

The queuing and preemption functions of DC-HSDPA UEs are the same as those of SC-HSDPA UEs. For details about queuing and preemption, see Load Control Feature Parameter Description. Issue 03 (2014-03-31)


14



3.2.5 LDR and OLC After the Flexible Dual Carrier HSDPA feature is applied, the RNC monitors the load status of each cell and triggers LDR or OLC. For details about how to monitor the load status of a cell, see section 3.2.1 Load Measurement. For DC-HSDPA UEs, the RNC performs LDR only on the UEs that use the current cell as the primary cell. The LDR function is the same as that before the Flexible Dual Carrier HSDPA feature is applied. If LDR is implemented through inter-frequency handovers, the target cell cannot be a secondary cell of the UE. The OLC function is the same as that before the Flexible Dual Carrier HSDPA feature is applied. For details about LDR and OLC, see Load Control Feature Parameter Description and Overload Control Feature Parameter Description.

3.3 Dynamic Cell Shutdown During off-peak hours, one or more cells in co-coverage areas can be shut down to reduce the power consumption of the NodeB. The following two features describe dynamic shutdown of cells: l

WRFD-020117 Multi-Carrier Switch off Based on Traffic Load

l

WRFD-020122 Multi-Carrier Switch off Based on QoS.

The Flexible Dual Carrier HSDPA feature can be used with the dynamic cell shutdown function. After the Flexible Dual Carrier HSDPA feature is activated, the following condition is added for shutting down a cell: The number of DC-HSDPA UEs in the cell must be less than or equal to the value of the McHsdpaUserNumThd(BSC6900,BSC6910) parameter in the ADD UCELLDYNSHUTDOWN command. For details about how to estimate the downlink power of a cell, see 3.2.1 Load Measurement. For details about the dynamic cell shutdown function, see Green BTS Feature Parameter Description.

3.4 Multi-Carrier HSDPA Scheduling Each UE is assigned a MAC-ehs entity. The MAC-ehs entity assigned to a DC-HSDPA UE performs joint scheduling between the primary and secondary cells. After the Flexible Dual Carrier HSDPA feature is introduced, the NodeB supports joint scheduling for all DC-HSDPA UEs in different cells. The NodeB ranks DC-HSDPA UEs according to user priority and allocates the resources in the primary and secondary cells to the UE. The NodeB takes more resources from cells with a lighter load and fewer resources from cells with a heavier load in the group to allocate to UEs. In this way, the resources of cells with a heavier load are reserved for SC-HSDPA UEs. For details about joint scheduling, see HSDPA Feature Parameter Description. Issue 03 (2014-03-31)


15



3.5 Activation and Deactivation of Supplementary Carrier The NodeB deactivates the supplementary carrier for a dual-carrier user when the user's traffic volume is low. When the traffic volume rises, the NodeB reactivates the supplementary carrier and the user becomes a dual-carrier user again. When one carrier is enough to carry the data sources and throughput for a user, the DC-HSDPA supplementary carrier can be deactivated for the user. Only the ACK/NACK and CQI messages over the primary carrier are transmitted on the HS-DPCCH. In this way, the HS-DPCCH power and the uplink load are reduced. When the data sources and throughput for a user exceed the capability of one carrier, the supplementary carrier will be reactivated for the user. For details, see Traffic-Based Activation and Deactivation of the Supplementary Carrier In Multi-carrier Feature Parameter Description.

Related Features

4.1 Prerequisite Features If multiple cells in a multi-carrier cell group operate in the same frequency band, the cells that operate in the same frequency band must have the WRFD-010696 DC-HSDPA feature enabled.

4.2 Mutually Exclusive Features If the Flexible Dual Carrier HSDPA feature is used with the WRFD-010684 2×2 MIMO feature in a cell, the Primary/Secondary common Pilot (PSP) mode must be used for the MIMO. For details, see MIMO Feature Parameter Description.

4.3 Impacted Features RAN Sharing and MOCN The Flexible Dual Carrier HSDPA feature can be enabled in RAN sharing or Multi-Operator Core Network (MOCN) scenarios. When the Flexible Dual Carrier HSDPA feature is enabled in RAN sharing or MOCN scenarios, run the RNC MML command SET UOPERATORSHARINGMODE to set InterPlmnMultiCarrSwitch(BSC6900,BSC6910) to YES. This allows UEs to use cells belonging to different operators as primary and secondary cells, but each UE must use its operator's cell as the primary cell. The secondary cell can belong to other operators. When InterPlmnMultiCarrSwitch(BSC6900,BSC6910) is set to NO, the UE must use its operator's cells as the primary and secondary cells.

DC-HSUPA The Flexible Dual Carrier HSDPA feature does not affect the configuration of DC-HSUPA. When the Flexible Dual Carrier HSDPA feature is used with DC-HSUPA, a DC-HSDPA UE can use DC-HSUPA only when the DC-HSUPA group is the same as the DC-HSDPA group. Issue 03 (2014-03-31)

Figure 4-1 shows an example of using the Flexible Dual Carrier HSDPA feature and DCHSUPA together. Figure 4-1 Example of using the Flexible Dual Carrier HSDPA feature and DC-HSUPA together

Figure 4-1 assumes that a multi-carrier cell group has three cells (F1, F2, and F3) and the Flexible Dual Carrier HSDPA feature is activated in the cells. If F1 and F2 are configured as a DCHSUPA group, only DC-HSDPA UEs that use F1 and F2 as the primary and secondary cells can establish DC-HSUPA connections in the uplink, and other DC-HSDPA UEs cannot establish DC-HSUPA connections in the uplink.

System Capacity This feature reduces the difference between the downlink load of cells in a multi-carrier cell group. The effect of this feature depends on the number of DC-HSDPA UEs and their traffic volume. A larger number of DC-HSDPA UEs and a larger traffic volume results in smaller difference between the downlink load of cells.

Network Performance Cells in a multi-carrier cell group have the same time offset (specified by the Tcell (BSC6900,BSC6910) parameter). When multiple cells (three or four) served by the same RRU in a sector transmit data at full power, the peak-to-average ratio (PAR) of the RRU increases if a higher-order modulation scheme is used in the downlink. As a result, cell throughput may decrease. On live networks, cells in the same sector do not transmit data at full power for a long period of time, and therefore cell throughput only slightly decreases. After Flexible Dual Carrier HSDPA is activated in networks with a low load, the data rates of DC-HSDPA UEs increase because UEs can fully utilize frequency resources. As network load increases, the gain provided by this feature decreases. The difference between the downlink load of cells in a multi-carrier cell group before this feature is activated also affects the gain provided by this feature. A larger difference results in a greater gain.

6 Engineering Guidelines

Engineering Guidelines

6.1 When to Use Flexible Dual Carrier HSDPA This feature is recommended in the following scenarios: l

There are more than two inter-frequency co-coverage cells.

l

A large proportion of UEs support DC-HSDPA.

l

The downlink load of inter-frequency co-coverage cells is low.

When the downlink load is high or the proportion of UEs supporting DC-HSDPA is small, the gain provided by this feature is low. For details about the impact of downlink load or the proportion of UEs supporting DC-HSDPA on this feature, see section 6.5.1 Factors Affecting Feature Benefits.

6.2 Required Information Before feature deployment, operators need to collect the following information: l

Frequencies, and bandwidth

l

Proportion of UEs supporting DC-HSDPA

l

Cell downlink load

For details about the related counters, see section6.5.2 Feature Benefits Monitoring.

6.3 Planning 6.3.1 RF Planning Before enabling the Flexible Dual Carrier HSDPA feature, plan the frequencies as described in 2.3.2 Cells Candidate for a Multi-Carrier Cell Group. Frequencies in the same frequency band can be either adjacent or non-adjacent. Figure 6-1 shows an example of three adjacent and non-adjacent frequencies in the same frequency band (band a). Issue 03 (2014-03-31)


20



Figure 6-1 Three frequencies in the same frequency band

6.3.2 Network Planning After you determine the frequency band and frequencies, determine multi-carrier cell groups and the multi-carrier HSDPA technologies for each cell. For details about the requirements, see sections 2.3.1 Multi-Carrier HSDPA Technologies and 2.3.2 Cells Candidate for a MultiCarrier Cell Group. On live networks, most operators have multiple inter-frequency co-coverage cells in urban areas and hotspots. Using multi-carrier HSDPA technologies and the Flexible Dual Carrier HSDPA feature together enables full utilization of frequency resources and supports a smooth evolution to future technologies. The following provides configuration suggestions for the typical scenario below. In this scenario, three or four inter-frequency co-coverage cells that operate in the same frequency band have been enabled with DC-HSDPA. The Flexible Dual Carrier HSDPA feature can be activated in this scenario. This feature helps flexibly allocate frequency resources and enable smooth multi-carrier evolution. Figure 6-2 shows an example of multi-carrier evolution in a single-band scenario. Figure 6-2 Example of multi-carrier evolution in a single-band scenario

RAN Sharing and MOCN In MOCN and RAN sharing scenarios, cells of different carriers can form a multi-carrier cell group when the InterPlmnMultiCarrSwitch(BSC6900,BSC6910) parameter is set to YES. For details about the implementation of the Flexible Dual Carrier HSDPA feature in RAN sharing and MOCN scenarios, see 4.3 Impacted Features. Issue 03 (2014-03-31)

Operating Environment l

One sector is deployed with three or four inter-frequency cells and these cells must be configured in the same downlink resource group. After the configuration of the multi-carrier cell group, the NodeB attempts to set up all cells in the multi-carrier cell group on the same board. If not all the cells are set up in the same group, the NodeB reports ALM-28206 Local Cell Capability Decline. NOTE

It is recommended that the Auto Rebuild Cell function be enabled. Run the SET NODEBRESALLOCRULE command to set the SW parameterto ON and specifying CS User Number Threshold and PS User Number Threshold. If the number of CS users and PS users in the downlink resource group is smaller than or equal to the thresholds, cells are reestablished automatically.

l

UEs are capable of at least one of the multi-carrier HSDPA technologies: DC-HSDPA.

l

When cells in a multi-carrier cell group that operate in the same frequency band use nonadjacent frequencies, UEs must support non-adjacent frequencies.

6.4.4 Precautions Before you configure a multi-carrier cell group, for example, if you want to add a cell to or remove a cell from the group, you need to deactivate all cells in the group first. Deactivating a cell interrupts the ongoing services in the cell. Therefore, configure a multi-carrier cell group during off-peak hours, for example, in the early morning.

6.4.5 Activation Using MML Commands Based on the network plan and prepared data, perform the following operations to activate the Flexible Dual Carrier HSDPA feature: Step 1 Run the RNC MML command DEA UCELL multiple times to deactivate each cell to be added to a multi-carrier cell group. Step 2 Configure a multi-carrier cell group on the NodeB side. A multi-carrier cell group can be either added or reconstructed from a DC-HSDPA group. l Adding a new multi-carrier cell group Perform the following operations to add a multi-carrier cell group: Run the NodeB MML command ADD NODEBMULTICELLGRP to add a multi-carrier cell group. Run the NodeB MML command ADD NODEBMULTICELLGRPITEM multiple times to add local cells to the multi-carrier cell group. l Reconstructing a multi-carrier cell group If the cells to be enabled with the Flexible Dual Carrier HSDPA feature have been configured as DC-HSDPA groups, operators can reconstruct a multi-carrier cell group from any DCHSDPA group and delete the other groups. The detailed operations are as follows: To reconstruct a DC-HSDPA group, run the NodeB MML command RMV NODEBMULTICELLGRPITEM or ADD NODEBMULTICELLGRPITEM to remove or add the local cells in the group. For the other DC-HSDPA groups, run the NodeB MML commands RMV NODEBMULTICELLGRPITEM and RMV MULTICELLGRP to remove them. NOTE

The multi-carrier cell group ID can be queried using the NodeB MML command LST MULTICELLGRP.

Step 3 (Optional) Run the RNC MML command MOD UCELLSETUP to modify the value of the Time Offset parameter based on the prepared data. NOTE

The value of the Time Offset parameter can be queried using the LST UCELL command.

Step 4 Run the SET NODEBRESALLOCRULE command to set the SW parameter to ON and setting the threshold CS User Number Threshold and PS User Number Threshold. If the number of CS users and PS users in the downlink resource group is smaller than or equal to the thresholds, cells are reestablished automatically. Issue 03 (2014-03-31)


26



Step 5 Run the RNC MML command ACT UCELL multiple times to activate each cell in the multicarrier cell group. Step 6 (Optional) If the multi-carrier HSDPA capability of a cell in the multi-carrier cell group changes, run the following commands to reconfigure parameters based on the network plan and prepared data.

6.4.6 Activation Observation Monitor counters or perform drive tests to check whether the Flexible Dual Carrier HSDPA feature is working properly.

Monitoring Counters Monitor the value of the following counter in cells of a multi-carrier cell group: VS.HSDPA.DC.PRIM.UE.Mean.Cell: Average number of DC-HSDPA UEs in anchor carrier in a Cell If the value of this counter is not zero for a cell, this feature is working properly for that cell.

Performing Drive Tests 1.

Prepare multiple test UEs. NOTE

Multiple test UEs are used to simultaneously perform FTP dialing tests so that every cell in the multicarrier cell group is tested.

2.

Start Uu interface trace on the RNC LMT for each test UE. In the displayed Uu Interface Trace dialog box, select RRC_RB_SETUP, as shown in Figure 6-4. Figure 6-4 Uu Interface Trace dialog box

3.

Use test UEs to perform FTP dialing tests in the coverage area of the multi-carrier cell group, and ensure that HSDPA connections are established.

4.

View the value of the "dl-SecondaryCellInfoFDD" IE in the RRC_RB_SETUP message in the traced signaling for the secondary cell information. Expected result: If all test UEs have established a DC-HSDPA radio bearer and every cell in the multi-carrier cell group serves as a primary or secondary cell for a test UE, this feature is working properly.

l

Removing the multi-carrier cell group

Table 6-5 describes the two methods. Table 6-5 Flexible Dual Carrier HSDPA feature deactivation methods Method

Advantage/Disadvantage

Operation

Disabling the Flexible Dual Carrier HSDPA feature in some cells of the multicarrier cell group

Advantage:

Run the RNC MML command MOD UCELLALGOSWITCH multiple times to disable the Flexible Dual Carrier HSDPA feature in some cells of the multi-carrier cell group. In this step, deselect DC_HSDPA (Cell DC-HSDPA Function Switch) in the Cell Hspa Plus function switch parameter.


Advantage:

l This method does not require cell deactivation, and therefore services are uninterrupted. Disadvantage: l N/A

l This method completely disables the Flexible Dual Carrier HSDPA feature. Disadvantage: l Deactivating a cell interrupts services in the cell. Therefore, perform this operation during offpeak hours, for example, in the early morning. l After the multi-carrier cell group is removed, each cell supports only R99 and SC-HSDPA connections in the downlink and the single-user downlink peak throughput decreases.

1. Run the RNC MML command DEA UCELL multiple times to deactivate each cell in the multi-carrier cell group. 2. Run the NodeB MML command RMV NODEBMULTICELLGRPITEM to remove all cells from the multi-carrier cell group. 3. Run the NodeB MML command RMV NODEBMULTICELLGRP to remove the multi-carrier cell group. 4. Run the RNC MML command ACT UCELL to reactivate the cells.

6.5 Performance Monitoring 6.5.1 Factors Affecting Feature Benefits l

Proportion of UEs supporting DC-HSDPA in a cell The smaller the proportion of UEs supporting DC-HSDPA the less the feature benefits.

Issue 03 (2014-03-31)


33


l


Traffic volume of DC-HSDPA UEs in a cell The feature benefits are greater in heavy-traffic scenarios, such as browsing web pages, or downloading MP3s, UE software, and ring tones. The feature benefits are less in the following scenarios: – The traffic volume of DC-HSDPA UEs is very low. For example, UEs are receiving only heartbeat packets (most heartbeat packets are less than 100 bytes in size). – DC-HSDPA UEs are performing full buffer services, such as bit torrent (BT) downloading, point-to-point service (P2P), and high definition movie downloading. In such scenarios, the feature benefits mainly result from diversity scheduling. When the number of DC-HSDPA users increases, the feature benefits decrease.

l

Cell load When downlink load is heavy or the number of online UEs is large in a cell, the feature benefits are limited.

In addition, when the difference between the downlink load of cells in a multi-carrier cell group is large, fairness among users cannot be ensured, and cell resources cannot be flexibly allocated. The Flexible Dual Carrier HSDPA feature flexibly schedules resources of different cells for HSDPA transmission of a UE, ensuring the fairness among users and improving resource utilization.

6.5.2 Feature Benefits Monitoring Use either of the following methods to monitor the feature benefits: l

Checking UE throughput

l

Checking the difference between the downlink load of cells in a multi-carrier cell group

The related counters are as follows: l

VS.HSDPA.MeanChThroughput This counter measures the UE throughput.

l

VS.MeanTCP This counter measures the cell load. If the value of this counter is large for cells in a multicarrier cell group, the feature benefits decrease.

l

VS.MeanTCP.NonHS This counter measures the downlink power resources consumed by non-HSDPA users. The larger the value of this counter, the less the feature benefits.

l

VS.MeanTCP.HSDPA.MC This counter measures the downlink power resources consumed by DC-HSDPA, DBHSDPA, and 4C-HSDPA users. The larger the value of this counter, the smaller the difference between the downlink load of cells in a multi-carrier cell group is.

l

Counters indicating the proportions of DC-HSDPA UEs in a cell – VS.HSDPA.DC.PRIM.UE.Mean.Cell: Average number of DC-HSDPA UEs using this cell as the primary cell – VS.HSDPA.DC.SEC.UE.Mean.Cell: Average number of DC-HSDPA UEs using this cell as the secondary cell – VS.HSDPA.UE.Mean.Cell: Average number of HSDPA UEs in a cell
