2 Overview

The hybrid automatic repeat request (HARQ) entity for High Speed Uplink Packet Access(HSUPA) is located on the NodeB side and used to receive MAC-e protocol data units (PDUs).When a cell cannot correctly receive MAC-e PDUs from a UE, the HARQ entity requires theUE to retransmit MAC-e PDUs. The average number of retransmissions on the NodeB sideneeds to converge to a target number of retransmissions on the RNC side. This target number on the RNC side is dynamically adjusted by the feature HSUPA Adaptive Retransmission.

With the HSUPA adaptive retransmission feature, a small target number of retransmissions isused under normal circumstances. When the uplink load or the UE transmit power is limited,one UE is selected to use a large target number of retransmissions during each period. Withoutthis feature, a small target number of retransmissions is always used. For details about theHSUPA adaptive retransmission feature, see HSUPA Feature Parameter Description .

In versions earlier than RAN14.0, the small target number of retransmissions is specified by the EdchTargetLittleRetransNum parameter and cannot be adaptively adjusted. When the uplink load is limited, a small target number of retransmissions will require a high signal-to-interferenceratio (SIR) on the Dedicated Physical Control Channel (DPCCH), and the DPCCH must have ahigher power. This leads to decreased available power on the Enhanced Dedicated Channel (E-DCH) and Enhanced Dedicated Physical Data Channel (E-DPDCH), a lower UE throughput,and a lower cell throughput. The feature Adaptive Adjustment of HSUPA Small TargetRetransmissions supports an alternative small target number of retransmissions for each typicaltype of service. The actual small target number of retransmissions can dynamically shift betweenthe original fixed number and the alternative number based on the cell uplink load and UE rates,which are configured by the EdchTargetLittleRetransNum and

EdchAltTarLittleRetransNum parameters, respectively. This improves the system capacitywhen the uplink load is limited.

This Adaptive Adjustment of HSUPA Small Target Retransmissions feature is only intendedfor the HSUPA services of the non-DC-HSUPA UEs.

Figure 2-1 shows the relationship between the features HSUPA Adaptive Retransmission andAdaptive Adjustment of HSUPA Small Target Retransmissions.

Figure 2-1 Relationship between the features HSUPA Adaptive Retransmission and AdaptiveAdjustment of HSUPA Small Target Retransmissions

The features HSUPA Adaptive Retransmission and Adaptive Adjustment of HSUPA SmallTarget Retransmissions are independent of each other. With the HSUPA AdaptiveRetransmission feature, only one UE is selected to use the large target number of retransmissionsduring each period. With the Adaptive Adjustment of HSUPA Small Target Retransmissionsfeature, when the uplink load is limited, multiple UEs are selected for adjustment to the smalltarget number of retransmissions. This further improves the cell throughput.

3 Technical Description

Without the feature Adaptive Adjustment of HSUPA Small Target Retransmissions, the RNCsets different target numbers for different typical types of services through the

EdchTargetLittleRetransNum parameter. This feature is intended to further improve the cellthroughput. An alternative small target number of retransmissions is available for each typicaltype of service. This alternative small number is configured by the

EdchAltTarLittleRetransNum parameter. The original small number is configured by the EdchTargetLittleRetransNum parameter. The small target number of retransmissionsdynamically shifts between EdchTargetLittleRetransNum and

EdchAltTarL ittleRetran sNum .

The Adaptive Adjustment of HSUPA Small Target Retransmissions feature dynamically adjuststhe small target number of retransmissions for each individual BE service over HSUPA. There

are two adjustment algorithms: RTWP-based Adjustment of HSUPA Small TargetRetransmissions and RSCP- and RTWP-based Adjustment of HSUPA Small TargetRetransmissions. The BASE_RSCP_RTWP_LITRETNUM_AUTOADJ_SWITCH under the RscpEffectAlgoSwitch parameter controls which adjustment algorithm is used.

RTWP-based Adjustment of HSUPA Small Target Retransmissions

Figure 3-1 shows the procedure for dynamically adjusting the small target number of retransmissions based on the RTWP.

WCDMA RANAdaptive Adjustment of HSUPA Small TargetRetransmissions Feature Parameter Description 3 Technical Description

Figure 3-1 Procedure for dynamically adjusting the small target number of retransmissions based on the RTWP

When the UE attempts to access the network, the larger value between EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum is used as the small targetnumber of retransmissions if PC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under the

PcSwitch parameter is selected, or EdchTargetLittleRetransNum is used if PC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under the PcSwitch parameter is notselected.

After the UE accesses the network, the following rules apply if PC_HSUPA_LITRETNUM_AUTO_ADJUST_SWITCH under the PcSwitch parameter isselected:

l If the UE rate is above the upper threshold and the uplink load of the cell has not reached MaxTargetUlLoadFactor multiplied by RelRatioforUlRTWP , the RNC adjusts the smalltarget number of retransmissions to the smaller one between

EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum in order to raise the UE

throughput. The upper threshold equals the minimum bit rate (MBR) of uplink servicesmultiplied by an unconfigurable factor.

l If the UE rate is below the lower threshold, the RNC adjusts the small target number of retransmissions to the larger one between EdchTargetLittleRetransNum and

EdchAltTarLittleRetransNum in order to raise the cell throughput on the uplink. The lower threshold equals the MBR of uplink services multiplied by an unconfigurable factor.

l In other cases, the RNC does not make any adjustments.

Table 3-1 lists the unconfigurable factors for different MBRs.

Figure 3-2 Procedure for dynamically adjusting the small target number of retransmissions based on the RSCP and RTWP

When a UE attempts to access the network, the following rules apply if PC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under the PcSwitch parameter andBASE_RSCP_RTWP_LITRETNUM_AUTOADJ_SWITCH under the

RscpEffectAlgoSwitch parameter are selected:

l If the uplink load of the cell is smaller than MaxTargetUlLoadFactor multiplied by RelRatioforUlRTWP and the UE coverage is not limited, the smaller one between EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum is used as the smalltarget number of retransmissions.

l In other cases, the larger one between EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum is used as the small target number of retransmissions.

The UE's uplink coverage is determined based on the P-CPICH RSCP, which can be obtainedfrom the periodically reported intra-frequency measurement reports. The

RrcRscpPeriodTimer parameter in the SET UCHLQUALITYEVALUATE commandspecifies the measurement period of the P-CPICH RSCP. A UE's uplink coverage is not limitedif the following conditions are met:

l If the duration between the current time and the time the RNC receives a measurementreport containing information about P-CPICH RSCP does not exceed the value of

EcN0EffectTime , the calibrated P-CPICH RSCP calculated based on the reported P-CPICH RSCP meets the following conditions:



8



– For UEs using the 2 ms TTI, the calibrated P-CPICH RSCP is greater than the value of BeTTI2msRscpUpThd .

– For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is greater than the valueof BeTTI10msRscpUpThd .

Calibrated P-CPICH RSCP = Reported P-CPICH RSCP – (Transmit power on the P-CPICH – 33 dBm)– (RTWP – (-105.2 d Bm))

l If the duration between the current time and the time the RNC receives a measurementreport containing information about P-CPICH RSCP exceeds the value of

EcN0EffectTime , the P-CPICH Ec/N0 in the RRC CONNECTION REQUEST message,CELL UPDATE message, or traffic volume-based event 4A/4B measurement report mustmeet the following conditions:

– For UEs using the 2 ms TTI, the P-CPICH Ec/N0 must be greater than the value of EcN0ThsFor2msTo10ms .

– For UEs using the 10 ms TTI, the P-CPICH Ec/N0 must be greater than the value of EcN0ThdForBaseCoverE2D .

The duration between the current time and the time the RNC receives an RRC CONNECTIONREQUEST or CELL UPDATE message is recorde d as durati on 1. The duration between thecurrent time and the time the RNC receives a traffic volume-based event 4A/4B measurementreport is recorded as duration 2. If both duration 1 and duration 2 are greater than the value of

EcN0EffectTime , the P-CPICH Ec/N0 is replaced by FakeEcNo .

NOTE

The RNC uses the P-CPICH Ec/N0 in a traffic volume-based event 4A/4B measurement report only whenthe DRA_PCPICH_ECN0_ON_RACH_UPDATE_SWITCH check box under the DraSwitch2

parameter in the SET UCORRMALGOSWITCH command is selected.

After the UE accesses the network, the following rules apply if PC_HSUPA_LITRETNUM_AUTO_ADJUST_SWITCH under the PcSwitch parameter and BASE_RSCP_RTWP_LITRETNUM_AUTOADJ_SWITCH under the

RscpEffectAlgoSwitch parameter are selected:

l If the UE rate is above the upper threshold and the uplink load of the cell has not reached MaxTargetUlLoadFactor multiplied by RelRatioforUlRTWP , the RNC adjusts the smalltarget number of retransmissions to the smaller one between

EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum in order to raise the UEthroughput in the uplink. The upper threshold equals the MBR of uplink services multiplied

by an unconfigurable factor (see Table 3-1 for details).l If the UE coverage is not limited and the uplink load of the cell has not reached

MaxTargetUlLoadFactor multiplied by RelRatioforUlRTWP , the RNC adjusts the smalltarget number of retransmissions to the smaller one between

EdchTargetLittleRetransNum and EdchAltTarLittleRetransNum in order to raise the UEthroughput in the uplink.

l If the UE rate is below the lower threshold, the RNC adjusts the small target number of retransmissions to the larger one between EdchTargetLittleRetransNum and

EdchAltTarLittleRetransNum in order to raise the cell throughput in the uplink when either of the following conditions is met: The uplink load of the cell has reached

MaxTargetUlLoadFactor multiplied by RelRatioforUlRTWP ; the UE coverage is limited.The lower threshold equals the MBR of uplink services multiplied by an unconfigurablefactor (see Table 3-1 for details).

l In other cases, the RNC does not make any adjustments.

The UE's uplink coverage is determined based on the P-CPICH RSCP, which can be obtainedfrom the periodically reported intra-frequency measurement reports. The

LittleRetranRabRscpPrd parameter in the SET UCHLQUALITYEVALUATE commandspecifies the measurement period of the P-CPICH RSCP.

A UE's uplink coverage is not limited if the following conditions are met:

l For UEs using the 2 ms TTI, the calibrated P-CPICH RSCP is greater than the value of BeTTI2msRscpUpThd .

l For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is greater than the value of BeTTI10msRscpUpThd .

A UE's uplink coverage is limited if the following conditions are met:

l For UEs using the 2 ms TTI, the calibrated P-CPICH RSCP is smaller than or equal to the

value of BeTTI2msRscpUpThd .l For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is smaller than or equal to the

value of BeTTI10msRscpUpThd .

Calibrated P-CPICH RSCP = Reported P-CPICH RSCP – (Transmit power on the P-CPICH – 33dBm)– (RTWP – (-105.2 dBm))

If the features HSUPA Adaptive Retransmission and Adaptive Adjustment of HSUPA SmallTarget Retransmissions are both enabled and the air interface resources or UE transmit power on the uplink is limited, the Adaptive Adjustment of HSUPA Small Target Retransmissionsfeature selects one UE to use the large target number of retransmissions during each period. If the selected UE later meets the conditions for using the small target number of retransmissions,

EdchTargetLittleRetransNum or EdchAltTarLittleRetransNum is used based on the settingfor the initial access of an HSUPA UE. For details about these conditions, see the HSUPA

5 Network Impact

System CapacityThis feature improves the uplink performance. The performance is affected by the uplink throughput and uplink load and the gain depends on the environment of the commercial network.It is recommended that this feature be enabled if the uplink load of the cell is restricted and thereare a large number of HSUPA UEs using a 10 ms TTI. If some UEs in the cell are engaged incontinuous uploading, this feature improves the uplink throughput by 10% to 15%. If all servicesin the cell are burst services, this feature lowers the RTWP by around 0.5 dB.

When the uplink load of the cell is not restricted and a large number of UEs are processing low-speed HSUPA services, the RSCP- and RTWP-based Adjustment of HSUPA Small TargetRetransmissions function increases the uplink throughput of the cell by up to about 5% comparedwith the RTWP-based Adjustment of HSUPA Small Target Retransmissions function, if someUEs are continuously performing upload services.

6 Engineering Guidelines

6.1 When to UseTo improvement HSUPA uplink throughput and reduce uplink RTWP, it is recommended thatthe RTWP-based Adjustment of HSUPA Small Target Retransmissions function be enabled inthe scenario where a large number of HSUPA UEs (more than two) use the 10 ms TTI.

It is recommended that the RSCP- and RTWP-based Adjustment of HSUPA Small TargetRetransmissions function be enabled in a cell that meets the following conditions:

l The uplink load of the cell is not restricted.

l More than 30% of HSUPA UEs have a low throughput.

6.2 Required InformationCollect the following information to determine whether to activate this feature:

l VS.HSUPA.UE.Mean.TTI10ms (HSUPA UEs using a 10 ms TTI)l VS.MeanRTWP (Mean Power of Totally Received Bandwidth for Cell)

l VS.HSUPA.MeanChThroughput.TotalBytes (Number of total bytes received in uplink of all the HSUPA MAC-d flows)

l Proportion of UEs with a low HSUPA throughput

The proportion of UEs with a low HSUPA throughput equals the number of HSUPA UEswith a low throughput divided by the value of the VS.CellDCHUEs counter. Generally, if the proportion exceeds 30% in a cell, the proportion of UEs with a low HSUPA throughputis considered as large. The number of HSUPA UEs with a low throughput equals the sumof all of the following counters:

VS.HSUPA.LowRateTTI2msUserNumber, VS.HSUPA.TTI2msUserNumber.0, andVS.HSUPA.TTI2msUserNumber.1

VS.HSUPA.TTI10msUserNumber.0, VS.HSUPA.TTI10msUserNumber.1,VS.HSUPA.TTI10msUserNumber.2, VS.HSUPA.TTI10msUserNumber.3,VS.HSUPA.TTI10msUserNumber.4, and VS.HSUPA.TTI10msUserNumber.5

6.4 Performance Monitoring When the uplink load is limited and there are multiple HSUPA UEs, this feature improves thecell throughput or reduces cell RTWP. To verify the effect of this feature, check the value of thecounter VS.HSUPA.MeanChThroughput.TotalBytes , which indicates the number of bytes inthe HSUPA MAC-d packets received in a cell and the value of the counter VS.MeanRTWP ,which indicates the average received total wideband power. With the traffic pattern unchanged,
