HSDPA Inter-Cell Power Sharing

3.2 HSDPA Inter-Cell Power Sharing This chapter describes the WRFD-160251 HSDPA Inter-Cell Power Sharing feature.

Overview With the HSDPA Inter-Cell Power Sharing feature, an HSDPA cell that has data to transmit but suffers power resource insufficiency can dynamically share the remaining power resources of an HSDPA cell in a power sharing group (with the same PA and sector). This feature supports a maximum of 4 HSDPA cells for power sharing. This increases the power usage and HSDPA throughput, thereby improving user experience. Assume that a power sharing group consists of two cells. The algorithm works as follows: If cell A has HSDPA data to transmit but the power resources are insufficient while cell B has remaining power resources, cell B can share its remaining power resources with cell A. When HSDPA data transmission in cell A is complete, cell B reclaims the shared power resources. If cell B has HSDPA data to transmit while HSDPA data transmission in cell A is in progress by sharing the power resources of cell B, cell B will instantly reclaim the shared power resources to ensure continued user experience. If a power sharing group consists of multiple cells, the algorithm works in the same way. Specifically, when multiple cells need to share the power resources of another cell, the remaining power resources are proportionally allocated to these cells based on their historical power. The cells whose historical power is large will be allocated more power resources. Figure 3-2 shows details of the algorithm. Figure 3-2 Dynamic power sharing between two HSDPA cells

If the average load of each cell in a power sharing group is heavy, the remaining power resources for sharing become scarce. In this situation, the feature gains on the total throughput are not obvious. If some cells in a power sharing group experience heavy load while other cells experience light load, the remaining power resources of lightly-loaded cells are always shared by heavily-loaded cells. This affects the experience of users in the lightly-loaded cells. Therefore, this feature is recommended only when the average load of each cell+ in a power sharing group is light. It is recommended that this function be used when the cells are both lightly loaded. For details, see section When to Use HSDPA Inter-Cell Power Sharing.

Technical Description When the HTOHPWSHSW parameter in the NodeB MML command SET ULOCELLALGPARA is set to ON for more than one cell under the NodeB, the RAN system determines whether the cells meet the power sharing requirements, for example, whether the cells use the same PA or share the same sector. If they do, they form a power sharing group. This feature periodically adjusts the power to be shared every 20 ms and provides no benefits for burst services that last less than this period. The adjustment is performed as follows: 1. Calculating the requested sharing-in or sharing-out power based on the average power usage of a previous period 

If the average power usage in the previous period is greater than or equal to 80% of Pmax (maximum configured power, specified by the MaxTxPower parameter), the cell is set to the "request shared-in" state, and the requested sharing-in power equals the smaller one between the value of the recommended requested sharing-in power and the value of Pmax multiplied by Rmax-share (ratio of the maximum cell power available for sharing to the maximum configured power which is specified by the MAXSHARINGRATIO parameter). The recommended value of the requested sharing-in power considers the average power usage of the cell in the previous period as well as the power sharing step (15%).



If the average power usage in the previous period is less than 80% of P max, the cell is set to the "request shared-out" state and the requested sharing-out power equals the smaller one between the value of the recommended requested sharing-out power and the value of Pmax x Rmax-share. The value of the recommended requested sharing-out power is calculated as follows: The recommended value of the requested sharing-out power is calculated as follows: Recommended requested sharing-out power = Remaining power in the previous period – Pmax × Rshare-margin. Rshare-margin indicates the ratio of the reserved power to the maximum configured power of the source cell, which is specified by the SHARINGMARGIN parameter.

2. Calculating the actual power to be shared between cells based on the requested sharing-in or sharing-out power of each cell 

If a power sharing group contains cells in both the "request sharing-in" and "request sharing-out" states, the actual power to be shared is the smaller one between the sum of the requested sharing-in power of each cell and sum of the requested sharing-out power of each cell. When multiple cells are in the "request sharing-in" state, remaining power resources are proportionally allocated to these cells based on their average power usage in the previous period. The cells whose average power usage is high in the previous period will be allocated more power resources.



In other scenarios, the value of the actual power to be shared between cells is 0.

3. Using the values about the actual power to be shared

For a cell in the "request sharing-in" state, the power allocated to its HSDPA services equals the value of Pmax plus the actual power to be shared between cells. For a cell in the "request sharing-out" state, the power allocated to its HSDPA services equals the value of Pmax minus the actual power to be shared between cells. 

4.2 WRFD-160251 HSDPA Inter-Cell Power Sharing Prerequisite Features  WRFD-010610 HSDPA Introduction Package

Mutually Exclusive Features  MRFD-221801 Multi-mode Dynamic Power Sharing (UMTS)

Impacted Features  WRFD-030010 CQI Adjustment Based on Dynamic BLER Target The HSDPA Inter-Cell Power Sharing feature causes variations in available HSDPA resources. The CQI Adjustment Based on Dynamic BLER Target feature enables the NodeB to dynamically select a proper BLER target for HSDPA users in a cell based on available cell resources and channel quality fluctuations, thereby achieving optimal throughput for HSDPA users. It is recommended that the HSDPA Inter-Cell Power Sharing feature be enabled while the CQI Adjustment Based on Dynamic BLER Target feature is enabled.  WRFD-150236 Load Based Dynamic Adjustment of PCPICH It is recommended that the HSDPA Inter-Cell Power Sharing feature not be enabled while the Load Based Dynamic Adjustment of PCPICH feature is enabled. The Load Based Dynamic Adjustment of PCPICH feature decreases the P-CPICH transmit power for cells with heavy traffic, thereby increasing cell capacity. However, this feature reduces the Ec/No of users and increases the call drop rate. The HSDPA Inter-Cell Power Sharing feature increases the maximum transmit power of cells with light traffic to improve user experience. However, this feature also reduces the Ec/No of users. If both features are enabled, call drop rate will deteriorate.  WRFD-150235 DPCH Maximum Power Restriction When the cell load is high, the DPCH Maximum Power Restriction feature restricts the downlink DPCH transmit power, and therefore users at the cell edge may experience downlink synchronization failures. If the HSDPA Inter-Cell Power Sharing feature is enabled while the DPCH Maximum Power Restriction feature is enabled, the average cell load becomes higher, and users at the cell edge are more likely to experience call drops. Therefore, it is recommended that these two features not be enabled together.  WRFD-010696 DC-HSDPA/WRFD-150209 DB-HSDPA/WRFD-150250 3CHSDPA/WRFD-150207 4C-HSDPA/WRFD-150208 Flexible Dual Carrier HSDPA The HSDPA Inter-Cell Power Sharing feature does not provide gains for multi-carrier users when the power sharing cell groups belong to the same multi-carrier cell group, because multi-carrier users can use available resources of multiple carriers. Since the multi-carrier user penetration rate has increased on live networks, gains provided by this feature have been declining.

 WRFD-021311 MOCN It is recommended that the HSDPA Inter-Cell Power Sharing feature not be enabled while the MOCN feature is enabled, because power sharing between two cells owned by different operators leads to unfair power resource allocation.  WRFD-020116 Dynamic Power Sharing in Multi-Carriers An HSDPA cell cannot be enabled with both the HSDPA Inter-Cell Power Sharing and Dynamic Power Sharing in Multi-Carriers features. When both the features are enabled and meet the conditions for taking effect, the Dynamic Power Sharing in Multi-Carriers feature will not take effect.

5.2 WRFD-160251 HSDPA Inter-Cell Power Sharing System Capacity When this feature is used in multiple cells with light load, the power resource usage is improved. When the maximum power sharing ratio is set to a value ranging from 40% to 50%, the average user throughput increases by about 5% to 13%, and the average throughput of users with poor CQIs in the cells increases by 10% to 50%. The cell throughput gains are affected by the maximum power configured for the cell. The greater the configured power, the smaller the gains. If this feature is used in multiple cells with heavy load, the average user throughput does not increase because such cells have high power resource usage and remain few resources. If this feature is used among multiple cells with unbalanced load (for example, one cell always shares its power resources with another cell), the average user throughput in the cell that shares remaining power resources may deteriorate. It is recommended that this feature be disabled in this scenario.

Network Performance This feature increases the average transmit power of HS-PSDCHs that transmit data by approximately 10% to 20% and the average cell load by 2% to 5%. The CS/PS call drop rate and CS/PS RAB setup success rate may deteriorate due to increased downlink cell load and increased downlink inter-cell interference. If the deterioration is more serious than expected, lower the value of the MAXSHARINGRATIO parameter.

6.2 WRFD-160251 HSDPA Inter-Cell Power Sharing 6.2.1 When to Use HSDPA Inter-Cell Power Sharing 



It is recommended that this feature be enabled to further improve user experience in HSDPA data transmission in a cell with light load and good kPI. 

A cell is considered light loaded when the value of the VS.MeanTCP counter (average carrier transmit power during busy hours) is less than 70% and the value of the VS.MeanTCP.NonHS counter is less than 40%.



A KPI is considered good when the KPI (such as the CS/PS call drop rate and CS/PS RAB setup success rate) is better than the average KPI of the entire network.

This feature is not recommended when the proportion of multi-carrier users in a cell exceeds 80%.

NOTE: The multi-carrier users refer to users whose services are carried on DC/3C/4C carriers. The proportion of these carriers is calculated as follows: (VS.HSDPA.DC.PRIM.UE.Mean.Cell + VS.HSDPA.3C.PRIM.UE.Mean.Cell + VS.HSDPA.4C.PRIM.UE.Mean.Cell)/VS.HSDPA.UE.Mean.Cell. DB-HSDPA users are not considered during site selection because most RRUs and RFUs do not support DB co-PA at present and only a few RF modules support DB co-PA. 

This feature is not recommended between macro and micro cells in a macro and micro combined network.



If this feature is enabled for small-traffic services or ping services, the data transmission duration is very short, and therefore the shared power resources cannot be reclaimed in time. As a result, the service rate on the air interface is lowered, and the delay is prolonged. It is recommended that this feature be disabled for delay-sensitive services, such as ping services.

6.2.2 Required Information Collect the following information before feature deployment: Network KPI: CS call drop rate, PS call drop rate, CS RAB setup success rate, and PS RAB setup success rate RNC performance counter: VS.MeanTCP and VS.MeanTCP.NonHS NodeB performance counter: VS.PdschPwrRatio.Mean, VS.PdschPwrRatio.Data, VS.HSDPA.DataOutput.Traffic, VS.DATATTIRATIO.MEAN, VS.HSDPA.INACTIVEDATATTIRATIO.MEAN Whether the available HSDPA power is sufficient for inter-cell power sharing depends on whether the value of PWRMGN in the LST ULOCELLMACHSPARA command is less than 10% and whether the value of HspaPower in the LST UCELLHSDPA command is greater than -1 dB.

6.2.3 Deployment This section describes how to activate, verify, and deactivate HSDPA inter-cell power sharing.

HSDPA Inter-Cell Power Sh

NOTE: This feature does not require a license when the WRFD-261103 AAS Vertical Multiple Sectors feature takes effect. If RAN Sharing is enabled, the licensed value is allocated among the primary and secondary operators according to the value of the License Allocation for Multiple Operators parameter. Method 1: some license control items, such as Dynamic CE Function (per NodeB), can be allocated only through the common group. For the NodeB license allocation among multiple operators, see License Management Feature Parameter Description. 

Other requirements Only cells that are under the same sector and use the same PA can form a power sharing group. For co-PA in complex networking, such as the independent demodulation with mutiple RRUs in one cell, digital combination and splitting, 0.5/0.5 scenario, or virtual antenna mapping (VAM), co-PA cells must correspond to the same PAs. For example, cells 1 and 2 are co-PA cells only when both of them correspond to PAs 1 and 2. This feature is enabled in a cell that meets the following conditions: 

The cell has not been configured with MIMO.



The cell is not configured as an IMB cell.



The cell has not been configured with STTD.



The cell must not be served by RRUs in cold backup mode.

In AAS scenarios, this feature also poses the following restrictions: 



Power can be shared only between two split cells. In addition, split cells after the AAS Vertical Multiple Sectors feature is enabled first form an independent power sharing group. Power sharing is not supported in inter-frequency cells with different tilts.

6.2.3.4 Activation Observation 1.

Run the NodeB MML command DSP NODEBPAGRP to check whether a cell is added to a power sharing group. If it is, this feature has taken effect. If it is not, the cell does not meet the power sharing requirements.

2.

If the value of the NodeB counter VS.HSDPAPwrShare.TtiNum is greater than 0 in a measurement period, this feature has taken effect.

Performance Monitoring Gain Evaluation When the traffic volume is stable, the throughput of HSDPA users in a cell increases at the MAC layer during data transmission. The throughput can be calculated as follows: VS.HSDPA.DataOutput.Traffic/ [(VS.DATATTIRATIO.MEAN - VS.HSDPA.INACTIVEDATATTIRATIO.MEAN) x (SP) x 60]. SP indicates the statistical periods of the performance counters in the formula.

Impact on Performance Counters On the NodeB side, the values of counters related to the HSDPA transmit power may exceed 100%. Measurements on the RNC are based on reported NodeB common measurements. As specified in 3GPP specifications, the downlink transmit power in the reported common measurements ranges from 0% to 100% relative to the maximum configured transmit power. Therefore, the downlink transmit power in a cell cannot be accurately determined based on the performance counters on the RNC side after this feature is enabled. Relationships between the NodeB and RNC performance counters are changed as follows: Before the HSDPA Inter-Cell Power Sharing feature is enabled, the sum of VS.PdschPwrRatio.Mean and VS.MeanTCP.NonHS approaches to the value of VS.MeanTCP. After the HSDPA Inter-Cell Power Sharing feature is enabled, the sum of VS.PdschPwrRatio.Mean and VS.MeanTCP.NonHS may be greater than the value of VS.MeanTCP. The calculation formula is as follows:

Where VS.PdschPwrRatio.Mean: Indicates the average transmit power over the HS-PDSCH in a cell, in the unit of ‰. This is a NodeB counter. VS.MeanTCP.NonHS: indicates the average downlink non-HSDPA carrier transmit power in a cell, in the unit of dBm. This is an RNC counter. VS.MeanTCP: Indicates the average carrier transmit power in a cell, in the unit of dBm. This is an RNC counter. MaxTxPower: Indicates the maximum configured transmit power in a cell, in the unit of 0.1 dBm. This is an RNC counter.

KPI Monitoring The CS/PS call drop rate and CS/PS RAB setup success rate slightly deteriorate after the HSDPA Inter-Cell Power Sharing feature is enabled.

6.2.5 Parameter Optimization If the KPI deterioration is more serious than expected, lower the value of the MAXSHARINGRATIO parameter.

6.2.6 Troubleshooting If you cannot observe whether the WRFD-160251 HSDPA Inter-Cell Power Sharing feature has taken effect in a cell, the cell does not meet the conditions for power sharing. For details, see 6.2.3.1 Requirements. In this situation, it is recommended that this feature be enabled in other cells under the same site as this cell or in the cells under other sites.
