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 numberon 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 theEdchTargetLittleRetransNum(BSC6900,BSC6910)parameter and cannot be adaptivelyadjusted. When the uplink load is limited, a small target number of retransmissions will requirea high signal-to-interference ratio (SIR) on the Dedicated Physical Control Channel (DPCCH),and the DPCCH must have a higher power. This leads to decreased available power on theEnhanced Dedicated Channel (E-DCH) and Enhanced Dedicated Physical Data Channel (E-DPDCH), a lower UE throughput, and a lower cell throughput. The feature Adaptive Adjustmentof HSUPA Small Target Retransmissions supports an alternative small target number ofretransmissions for each typical type of service. The actual small target number ofretransmissions can dynamically shift between the original fixed number and the alternativenumber based on the cell uplink load and UE rates, which are configured by theEdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) parameters, respectively. This improves the system capacity when theuplink 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 theEdchTargetLittleRetransNum(BSC6900,BSC6910) parameter. This feature is intended tofurther improve the cell throughput. An alternative small target number of retransmissions isavailable for each typical type of service. This alternative small number is configured by theEdchAltTarLittleRetransNum(BSC6900,BSC6910) parameter. The original small number isconfigured by the EdchTargetLittleRetransNum(BSC6900,BSC6910) parameter. The smalltarget number of retransmissions dynamically shifts between EdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910).

The Adaptive Adjustment of HSUPA Small Target Retransmissions feature dynamically adjuststhe small target number of retransmissions for each individual BE service over HSUPA. Thereare 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 underthe RscpEffectAlgoSwitch(BSC6900,BSC6910) parameter controls which adjustmentalgorithm is used.

RTWP-based Adjustment of HSUPA Small Target RetransmissionsFigure 3-1 shows the procedure for dynamically adjusting the small target number ofretransmissions 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 retransmissionsbased on the RTWP

When the UE attempts to access the network, the larger value betweenEdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) is used as the small target number of retransmissions ifPC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under the PcSwitch(BSC6900,BSC6910) parameter is selected, or EdchTargetLittleRetransNum(BSC6900,BSC6910) is used if PC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under thePcSwitch(BSC6900,BSC6910) parameter is not selected.

After the UE accesses the network, the following rules apply ifPC_HSUPA_LITRETNUM_AUTO_ADJUST_SWITCH under the PcSwitch(BSC6900,BSC6910) parameter is selected:

l If the UE rate is above the upper threshold and the uplink load of the cell has not reachedMaxTargetUlLoadFactor(BSC6900,BSC6910) multiplied by RelRatioforUlRTWP(BSC6900,BSC6910), the RNC adjusts the small target number of retransmissions to thesmaller one between EdchTargetLittleRetransNum(BSC6900,BSC6910) andEdchAltTarLittleRetransNum(BSC6900,BSC6910) in order to raise the UE throughput.



7

The upper threshold equals the maximum bit rate (MBR) of uplink services multiplied byan unconfigurable factor.

l If the UE rate is below the lower threshold, the RNC adjusts the small target number ofretransmissions to the larger one between EdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) in order toraise the cell throughput on the uplink. The lower threshold equals the MBR of uplinkservices 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.

Table 3-1 Unconfigurable factors for different MBRs

MBR (Mbit/s) UnconfigurableFactor for the UpperThreshold

UnconfigurableFactor for theLowerThreshold

< 1 90% 60%

≥ 1, excluding the following:l Services with Quadrature Phase

l Services with 16QAM modulationand an 11.52 Mbit/s MBR

90% 70%

5.44 (QPSK modulation) 75% 70%

11.52 (16QAM modulation) 75% 70%

This function also takes effect in the following scenario: PTT + single BE (carried on theE-DCH) combined services. When RESERVED_SWITCH_14_BIT3 under the RNC-level switch RsvSwitch14(BSC6900,BSC6910) is selected, the function of RTWP-basedAdjustment of HSUPA Small Target Retransmissions takes effect if there is no datatransmission for PTT services.

RSCP- and RTWP-based Adjustment of HSUPA Small Target RetransmissionsThe following figure shows the procedure for dynamically adjusting the small target number ofretransmissions based on the RSCP and RTWP.

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

When a UE attempts to access the network, the following rules apply ifPC_HSUPA_LITRETNUM_INIT_SEL_SWITCH under the PcSwitch(BSC6900,BSC6910) parameter andBASE_RSCP_RTWP_LITRETNUM_AUTOADJ_SWITCH under theRscpEffectAlgoSwitch(BSC6900,BSC6910) parameter are selected:

l If the uplink load of the cell is smaller than MaxTargetUlLoadFactor(BSC6900,BSC6910) multiplied by RelRatioforUlRTWP(BSC6900,BSC6910) and theUE coverage is not limited, the smaller one between EdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) is used asthe small target number of retransmissions.

l In other cases, the larger one between EdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) is used asthe 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(BSC6900,BSC6910) 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 ofEcN0EffectTime(BSC6900,BSC6910), the calibrated P-CPICH RSCP calculated basedon the reported P-CPICH RSCP meets the following conditions:

– For UEs using the 2 ms TTI, the calibrated P-CPICH RSCP is greater than the value ofBeTTI2msRscpUpThd(BSC6900,BSC6910).

– For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is greater than the valueof BeTTI10msRscpUpThd(BSC6900,BSC6910).



9

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

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(BSC6900,BSC6910), the P-CPICH Ec/N0 in the RRC CONNECTION REQUESTmessage, CELL UPDATE message, or traffic volume-based event 4A/4B measurementreport must meet the following conditions:

– For UEs using the 2 ms TTI, the P-CPICH Ec/N0 must be greater than the value ofEcN0ThsFor2msTo10ms(BSC6900,BSC6910).

– For UEs using the 10 ms TTI, the P-CPICH Ec/N0 must be greater than the value ofEcN0ThdForBaseCoverE2D(BSC6900,BSC6910).

The duration between the current time and the time the RNC receives an RRC CONNECTIONREQUEST or CELL UPDATE message is recorded as duration 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 ofEcN0EffectTime(BSC6900,BSC6910), the P-CPICH Ec/N0 is replaced by FakeEcNo(BSC6900,BSC6910).

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 DraSwitch2parameter in the SET UCORRMALGOSWITCH command is selected.

After the UE accesses the network, the following rules apply ifPC_HSUPA_LITRETNUM_AUTO_ADJUST_SWITCH under the PcSwitch parameterand BASE_RSCP_RTWP_LITRETNUM_AUTOADJ_SWITCH under theRscpEffectAlgoSwitch(BSC6900,BSC6910) parameter are selected:

l If the UE rate is above the upper threshold and the uplink load of the cell has not reachedMaxTargetUlLoadFactor(BSC6900,BSC6910) multiplied by RelRatioforUlRTWP(BSC6900,BSC6910), the RNC adjusts the small target number of retransmissions to thesmaller one between EdchTargetLittleRetransNum(BSC6900,BSC6910) andEdchAltTarLittleRetransNum(BSC6900,BSC6910) in order to raise the UE throughputin the uplink. The upper threshold equals the MBR of uplink services multiplied by anunconfigurable factor (see Table 3-1 for details).

l If the UE coverage is not limited and the uplink load of the cell has not reachedMaxTargetUlLoadFactor(BSC6900,BSC6910) multiplied by RelRatioforUlRTWP(BSC6900,BSC6910), the RNC adjusts the small target number of retransmissions to thesmaller one between EdchTargetLittleRetransNum(BSC6900,BSC6910) andEdchAltTarLittleRetransNum(BSC6900,BSC6910) in order to raise the UE throughputin the uplink.

l If the UE rate is below the lower threshold, the RNC adjusts the small target number ofretransmissions to the larger one between EdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910) in order toraise the cell throughput in the uplink when either of the following conditions is met: Theuplink load of the cell has reached MaxTargetUlLoadFactor(BSC6900,BSC6910)multiplied by RelRatioforUlRTWP(BSC6900,BSC6910); the UE coverage is limited. Thelower threshold equals the MBR of uplink services multiplied by an unconfigurable factor(see Table 3-1 for details).



10

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. TheLittleRetranRabRscpPrd(BSC6900,BSC6910) parameter in the SETUCHLQUALITYEVALUATE command specifies the measurement period of the P-CPICHRSCP.

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 ofBeTTI2msRscpUpThd(BSC6900,BSC6910).

l For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is greater than the value ofBeTTI10msRscpUpThd(BSC6900,BSC6910).

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 thevalue of BeTTI2msRscpUpThd(BSC6900,BSC6910).

l For UEs using the 10 ms TTI, the calibrated P-CPICH RSCP is smaller than or equal to thevalue of BeTTI10msRscpUpThd(BSC6900,BSC6910).

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 poweron 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. Ifthe selected UE later meets the conditions for using the small target number of retransmissions,EdchTargetLittleRetransNum(BSC6900,BSC6910) or EdchAltTarLittleRetransNum(BSC6900,BSC6910) is used based on the setting for the initial access of an HSUPA UE. Fordetails about these conditions, see the HSUPA Feature Parameter Description.

This function also takes effect in the following scenario: PTT + single BE (carried on the E-DCH) combined services. When RESERVED_SWITCH_14_BIT3 under the RNC-levelswitch RsvSwitch14(BSC6900,BSC6910) is selected, the function of RSCP- and RTWP-basedAdjustment of HSUPA Small Target Retransmissions takes effect if there is no data transmissionfor PTT services.

5 Network Impact

System CapacityThis feature improves the uplink performance. The performance is affected by the uplinkthroughput 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.

Network PerformanceNo impact.

6 Engineering Guidelines

6.1 When to Use Adaptive Adjustment of HSUPA SmallTarget Retransmissions

To 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, ifthe 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

6.3.4 Activation ObservationStep 1 Start a UE trace task on a UE that supports HSPA but not DC-HSDPA. That is, start a UE trace

task on a UE that does not belong to HS-DSCH category 21 or higher. On the RNC LMT mainpage, click Trace. In the displayed Trace Navigation Tree pane, choose Trace > UMTSServices > UE Trace. The UE Trace dialog box is displayed. In this dialog box, set the relatedparameters, and then click Submit. Check the RRC_RB_SETUP message in the tracing results.

Step 2 Use the UE to establish a PS BE download service and enable the uplink of the UE to use a 10ms TTI, so that the UE rate is smaller than the lower threshold (for details, see 3 TechnicalDescription).

Expected result: The HSUPA service is carried on the E-DCH and uses a 10 ms TTI, as shownin Figure 6-1.

Figure 6-1 RRC_RB_SETUP message

Step 3 On the RNC LMT main page, click Monitor. In the displayed Monitor Navigation Tree pane,choose Monitor > UMTS Monitoring > Connection Performance Monitoring. TheConnection Performance Monitoring dialog box is displayed. In this dialog box, set MonitorItem to OLPC, and set IMSI to the same value as that in step 1. Then, check the average numberof transmissions on the E-DCH.

If the average number of retransmissions on the E-DCH (equals the average number oftransmissions on the E-DCH minus one) is close to the larger value betweenEdchTargetLittleRetransNum(BSC6900,BSC6910) and EdchAltTarLittleRetransNum(BSC6900,BSC6910), this feature has been activated. For example, the average number oftransmissions on the E-DCH is 1.0821, the average number of retransmissions on the E-DCHis 0.0821, and the default values of EdchTargetLittleRetransNum(BSC6900,BSC6910) andEdchAltTarLittleRetransNum(BSC6900,BSC6910) are 0.01 and 0.1, respectively for UEsusing a 10 ms TTI. In this case, the average number of retransmissions on the E-DCH is closeto the value of EdchAltTarLittleRetransNum(BSC6900,BSC6910), and this feature has beenactivated.

Step 4 Observe the following counters to see if the feature goes into effect.l When the RTWP-based Adjustment of HSUPA Small Target Retransmissions function is

enabled, this function has been activated if the values of the counters listed in Table 6-4 aregreater than zero.

l When the RSCP- and RTWP-based Adjustment of HSUPA Small Target Retransmissionsfunction is enabled, this function has been activated if the values of the counters listed inTable 6-4 are greater than zero.
