WCDMA RANCPC Feature Parameter Description 2 CPC-DTX/DRX


3

2.1 OverviewDTX-DRX consists of the DTX (Discontinuous Transmission of the uplink DPCCH) and theDRX (Discontinuous Reception of the downlink HS-SCCH). The feature of DTX-DRX allowsa UE to shut down its receiver and transmitter at a specific time and thus reduces the uplinkinterference and UE power consumption.The requirements of DTX-DRX are listed in Table 2-1.

Table 2-1 Requirements of DTX-DRX for NEsItem RequirementCN NoneRNC The RNC also needs to control the use of DTX-DRX during RB setup,

reconfiguration, and handover.The RNC needs to support the configuration of the DTX-DRX transmissionpattern.

NodeB The NodeB can configure, reconfigure, activate, and deactivate DTX or DRX.UE UEs must support CPC-DTX/DRX.

2.2 Basic PrincipleUplink DTX

The uplink DTX function allows a UE to automatically stop data transmission on the uplinkDPCCH when there is no data to transmit on the E-DCH and HS-DPCCH, thereby reducinginterference from the DPCCH. The UE periodically transmits DPCCH bursts in each DTX cycleto maintain power control and link synchronization. For details about the conditions under whicha UE automatically stops data transmission on the uplink DPCCH, see section 6C.2"Discontinuous uplink DPCCH transmission operation" in 3GPP TS 25.214 V9.0.0.According to section 6C.2.1 "Uplink DPCCH burst pattern" in 3GPP TS 25.214 V9.0.0, if thereis data to transmit on the E-DCH, the data can be transmitted only at the time defined by UplinkDPCCH burst pattern. As a result, the ping service delay is increased, and the web browsingservice delay is increased. The larger the web page, the longer the web browsing service delay.Uplink DTX is of importance for services such as VoIP and web browsing, with intermittentdata transmission.Figure 2-1 shows the impact of uplink DTX.

Figure 2-1 Impact of uplink DTX

Note that if the E-DCH data is transmitted continuously, the DPCCH has to be transmitted andDTX becomes unavailable.For details about the basic principle of uplink DTX, see section 6C.1 "Uplink CQI transmission"in 3GPP TS 25.214 V9.0.0.

Downlink DRXThe UE in connected mode needs to listen to the control channel (HS-SCCH) continuously andtherefore power consumption is high. If downlink DRX is used, the UE needs to receive the HS-SCCH only at some time points.According to section 6C.3 "Discontinuous downlink reception" in 3GPP TS 25.214 V9.0.0, ifa UE has data to transmit, the UE can receive the data from the HS-SCCH only at the timedefined by HS-SCCH reception pattern. As a result, the ping service delay is increased, and theweb browsing service delay is increased. The larger the web page, the longer the web browsingservice delay.Figure 2-2 shows the impact of downlink DRX.

Figure 2-2 Impact of downlink DRX

Downlink DRX depends on uplink DTX. Therefore, downlink DRX can be activated only afteruplink DTX is activated. Downlink DRX, together with uplink DTX, allows the UE toperiodically shut down the TX and RX function in the UE, lowering the UE battery consumptionand prolonging the UE battery life.For details about the basic principle of downlink DRX, see section 6C.3 "Discontinuousdownlink reception" in 3GPP TS 25.214 V9.0.0.

HS-SCCH OrderIn 3GPP release 7, HS-SCCH order is introduced and carried on HS-SCCH type 1 (non-MIMOUEs) and HS-SCCH type 3 (MIMO UEs). Bit fields on HS-SCCH are fixed to a value to indicatea specific HS-SCCH function.After the RNC configure a UE with DTX-DRX, the NodeB can activate/deactivate DTX or DRXrespectively by sending HS-SCCH order to this UE.

2.3 Radio BearersCPC DTX-DRX is an optional feature. A prerequisite for using CPC is that HSDPA, HSUPA,and SRB over HSPA are activated.l The DCH is not configured in the uplink and downlink. The E-DCH is configured in the

uplink, and the HS-DSCH and F-DPCH are configured in the downlink.l Signaling and data are carried on HSPA channels. Therefore, CPC is dependent on SRB

over HSDPA and SRB over HSUPA.DTX/DRX can be selected if the following conditions are met:l DTX/DRX is supported by the network and the UE, and it is activated.

To activate DTX/DRX, select DTX_DRX of the HspaPlusSwitch parameter, andCFG_HSPA_DTX_DRX_SWITCH of the CfgSwitch parameter.

l The SRB is carried on HS-DSCH for the downlink and E-DCH for the uplink. For details,see Radio Bearers Feature Parameter Description.

l The service type is CS voice over HSPA service, PS voice service, PS streaming service,or PS BE service.

l The downlink HS-DSCH and uplink E-DCH are selected as transport channels.

2.4 Transmission PatternFor details of the transmission pattern, see 3GPP TS 25.214.There are two UE DTX cycles, namely cycle 1 and cycle 2. Generally, the UE uses cycle 1 foruplink DTX. If the UE has no data to transmit for a long time, the UE uses cycle 2 for uplinkDTX. At the beginning of each cycle, the UE sends a DPCCH burst. One burst may consist ofone, two, or five subframes.

Figure 2-3 Switching between cycle 1 and cycle 2



6

Figure 2-3 shows the switching between the two UE DTX cycles. The operator can set cycle-related information by using the RNC command SET UDTXDRXPARA for different servicesto increase the system capacity while ensuring QoS. The parameters are listed as follows:l DtxCycle1l DtxCycle2l MacDtxCyclel InactThsForCycle2l DtxLongPreamblel MacInactiveThresholdl DpcchBurst1l DpcchBurst2The operator can adjust the DRX cycles by using the RNC command SETUDTXDRXPARA to meet the requirements of the UE. The parameters are listed as follows:l Drxvalidl DrxCyclel InactThsForDrxCyclel CQIFbCkinInDTXDRXmode

2.5 State TransitionState transition from CELL_DCH (CPC) to CELL_FACH or enhanced CELL_FACH and statetransition from CELL_DCH (without CPC) to CELL_FACH use the same scheme. The onlydifference lies in parameter settings.For details about state transition from CELL_DCH (CPC) to CELL_FACH and fromCELL_DCH (CPC) to enhanced CELL_FACH, see State Transition Feature ParameterDescription.

2.6 Mobility ManagementA UE initiating a handover procedure supports DTX-DRX only when all cells in the active setfor the UE support DTX. When a cell in the active set does not support DTX-DRX, the UE doesnot support DTX-DRX either.You are advised to enable this feature for all cells instead of for only several cells in an activeset. This helps reduce reconfiguration signaling.

2.7 Power ControlDTX affects power control on the network side. When the network side does not detect signalsfrom a DTX UE on the uplink DPCCH, the network side suspends power control on the DTXUE. Network KPIs are not affected because UEs periodically send signals on the uplink DPCCHand power control can be performed on these UEs.



7

2.8 Load ControlFor a UE using DTX-DRX, the RNC performs admission on cells that are to be added to theactive set for the UE. For a UE that starts to use DTX-DRX, the RNC performs admission onall cells in the active set for the UE. In the uplink, the admission is performed on the E-DCH,not on the DPCCH. In the downlink, the admission is performed on the HS-DSCH. Theadmission policies for the E-DCH and HS-DSCH are the same as those before CPC - DTX /DRX is enabled.

2.9 HSDPA Scheduling AlgorithmFor a UE using DRX, scheduling can be performed for the UE at the HS-SCCH reception patternor during n subframes after HSDPA scheduling is complete. The value of n is specified byInactThsForDrxCycle.

2.10 Automatic Activation and Deactivation on NodeBsDRX is activated or deactivated based on the QoS. QoS specifications for DRX UEs aremonitored. When data to be transmitted in the MAC-ehs queue waits for a long period and theQoS cannot be guaranteed, DRX is deactivated. When data to be transmitted in the MAC-ehsqueue waits for a short period and the QoS can be guaranteed, DRX is activated.DTX is activated or deactivated based on the uplink throughput. DTX is activated or deactivatedbased on the uplink throughput. When a UE's uplink throughput is larger than 400 kbit/s,continuous transmission is required in the uplink E-DCH and DPCCH at the same time. In thiscase, DTX needs to be deactivated. When a UE's uplink throughput is less than 200 kbit/s, DTXcan be used to reduces the uplink interference. In this case, DTX needs to be activated.The activation and deactivation functions have no control switch and they are enabled by default.In addition, the QoS and uplink throughput thresholds are unconfigurable.

3 CPC HS-SCCH Less OperationThis section describes the WRFD-010687 CPC-HS-SCCH Less operation feature.

WCDMA RANCPC Feature Parameter Description 3 CPC HS-SCCH Less Operation


9

3.1 OverviewIn the case of HSDPA, for small-packet services such as VoIP, the power consumption of theHS-SCCH may be higher than that of a traffic channel. In addition, the HS-SCCH limits themaximum number of HSDPA users that can be scheduled in each TTI. This limitation resultsin increasing data transmission delay and decreasing user capacity of delay-sensitive services.The CPC HS-SCCH Less Operation feature allows the initial transmission without the HS-SCCH. Retransmission still requires the HS-SCCH. Thus, HS-SCCH Less Operation reducesthe power consumption and occupation of the HS-SCCH during downlink transmission, allowsmore services to be scheduled at the same time, and improves the system capacity.The requirements of HS-SCCH Less Operation are listed in Table 3-1.

Table 3-1 Requirements of HS-SCCH Less OperationItem RequirementCN NoneRNC The RNC also needs to control the use of HS-SCCH Less

Operation during RB setup, reconfiguration, and handover.RNC needs to configure all the data and signaling to the HSPAchannel. DCHs are not allowed with HS-SCCH Less Operation.

NodeB The NodeB needs to support the HS-SCCH type 2.The NodeB scheduler needs to determine finally whether to usethis feature in transmission if a UE is configured with the feature.

UE The UE needs to support the feature.

3.2 Basic PrincipleOverview

Figure 3-1 shows the principle of HS-SCCH Less Operation.



10

Figure 3-1 impact of HS-SCCH Less Operation

l Initial transmissionFor the initial transmission, the NodeB does not send the HS-SCCH to the UE. The NodeBadds the UE ID to the CRC information on the HS-DSCH and the UE can identify its data.Then, the UE decodes the data block on the HS-PDSCH. The UE is required to respondwith ACK after receiving correct data, but it need not respond with NACK in other cases.There is no control information during the initial transmission. Therefore, a predefined setof transport block sizes are used in the downlink, and the UE receives the data throughblind detection. In the case of HS-SCCH Less Operation, four predefined transport blocksizes and QPSK modulation can be used for transmission. The peak rate is limited to 742kbit/s. The operator can set the predefined transport block sizes by using the RNC commandSET UHSSCCHLESSOPPARA for different services

l RetransmissionIf the NodeB does not receive ACK from the UE after the initial transmission, it retransmitsthe data through the HS-DSCH and the control information through the HS-SCCH. Whetherthe retransmitted data is received is reported by the UE through ACK or NACK. Amaximum of two retransmissions are allowed.The RAN determines whether to use HS-SCCH Less Operation based on downlink trafficvolume.

HS-PDSCHThe CRC process is changed to support the feature.When the HS-SCCH Less Operation is applied, the NodeB does not transmit HS-SCCH. ForUE to identify the transmission on HS-PDSCH, the NodeB adds the UE ID information to theCRC of HS-DSCH block.

HS-SCCH Type 2To implement HS-SCCH Less Operation, a new HS-SCCH frame type, that is, HS-SCCH type2, is introduced. HS-SCCH type 2 carries the information about retransmission, such as thetransport block size, pointer to the previous transmission, and number of retransmissions. Fordetails, see section "Coding for HS-SCCH type 2" in 3GPP TS 25.212.

The comparison of HS-SCCH type 1 and type 2 is listed in the following table.

The coding method of part 1 is not changed, but the code number indicated by CCS is limitedto one or two. The MS is fixed to 0, which means the modulation is fixed to QPSK.The coding method of part 2 is changed to provide additional signaling to support HS-SCCHLess Operation.l Type field is fixed to a value so that a UE can identify the HS-SCCH type 2.l TBS index is used to indicate one of the four pre-configured TBS.l Pointer is used to indicate the previously transmitted position to assist soft combination.l ReTX is used to indicate the transmission times.l Reserve bit is not used.

3.3 Radio BearersCPC DTX-DRX is an optional feature. A prerequisite for using CPC is that HSDPA, HSUPA,and SRB over HSPA are activated.l The DCH is not configured in the uplink or downlink. The E-DCH is configured in the

uplink, and the HS-DSCH and F-DPCH are configured in the downlink.l Signaling and data are carried on HSPA channels. Therefore, CPC is dependent on SRB

over HSDPA and SRB over HSUPA.HS-SCCH Less Operation can be selected if the following conditions are met:l HS-SCCH Less Operation is supported by the network and the UE, and it is activated.

To activate HS-SCCH Less Operation, select HS_SCCH_LESS_OPERATION of theHspaPlusSwitch parameter, and CFG_HSPA_HSSCCH_LESS_OP_SWITCH of theCfgSwitch parameter.

l The SRB is carried on HS-DSCH for the downlink and E-DCH for the uplink. For details,see Radio Bearers Feature Parameter Description.

l The service type is CS voice over HSPA service, PS voice service, PS streaming service,or PS BE service.

l The downlink HS-DSCH and uplink E-DCH are selected as transport channels.



12

HS-SCCH Less Operation and MIMO cannot be used simultaneously. MIMO takes precedenceover HS-SCCH Less Operation. Therefore, HS-SCCH Less Operation cannot be selected ifMIMO is selected.

3.4 Mobility ManagementEnable the HS-SCCH Less operation feature only when the best cell supports this feature.Disable the HS-SCCH Less Operation feature if the best cell does not support this feature.

When CPC-DTX/DRX is enabled, gains from Adaptive Configuration of Traffic ChannelPower offset for HSUPA decrease. Likewise, when Adaptive Configuration of TrafficChannel Power offset for HSUPA is enabled, gains from CPC-DTX/DRX decrease.This is because CPC-DTX/DRX increases system capacity by reducing signals transmittedon the DPCCH and lowering interference from the DPCCH while Adaptive Configurationof Traffic Channel Power offset for HSUPA reduces the DPCCH power and thereforeleaves less interference from the DPCCH to be lowered.System throughput is always greater when CPC-DTX/DRX is enabled together withAdaptive Configuration of Traffic Channel Power offset for HSUPA, as compared withwhen CPC-DTX/DRX is not enabled together with Adaptive Configuration of TrafficChannel Power offset for HSUPA or none of the features is enabled.For details about Adaptive Configuration of Traffic Channel Power offset for HSUPA, seePower Control Feature Parameter Description.

This is because CPC-DTX/DRX increases system capacity by reducing signals transmittedon the DPCCH and lowering interference from the DPCCH while HSUPA AdaptiveTransmission reduces the DPCCH power and therefore leaves less interference from theDPCCH to be lowered.System throughput is always greater when CPC-DTX/DRX is enabled together withHSUPA Adaptive Transmission, as compared with when CPC-DTX/DRX is not enabledtogether with HSUPA Adaptive Transmission or none of the features is enabled.For details about HSUPA Adaptive Transmission, see HSUPA Feature ParameterDescription.

l WRFD-010210 Control Channel Parallel Interference Cancellation (CCPIC) and ControlChannel Parallel Interference Cancellation (Phase 2)When CPC-DTX/DRX is enabled, gains from CCPIC decrease. Likewise, when CCPIC isenabled, gains from CPC-DTX/DRX decrease.This is because CPC-DTX/DRX increases system capacity by reducing signals transmittedon the DPCCH and lowering interference from the DPCCH while CCPIC increases systemcapacity by canceling interference from the DPCCH and therefore leaves less interferencefrom the DPCCH to be lowered.System throughput is always greater when CPC-DTX/DRX is enabled together withCCPIC, as compared with when CPC-DTX/DRX is not enabled together with CCPIC ornone of the features is enabled.For details about Control Channel Parallel Interference Cancellation (CCPIC) and ControlChannel Parallel Interference Cancellation (Phase 2), see Interference CancellationFeature Parameter Description.

l WRFD-020500 Enhanced Fast DormancyAs CPC-DTX/DRX takes effect only on UEs in the CELL_DCH state, CPC-DTX/DRXcan produce gains in the uplink capacity only when UEs are in the CELL_DCH state.However, Enhanced Fast Dormancy can accelerate the state transition of UEs fromCELL_DCH to CELL_FACH, CELL_PCH, or URA_PCH. As a result, scenarios whereCPC-DTX/DRX takes effect are reduced.For details about Enhanced Fast Dormancy, see Enhanced Fast Dormancy FeatureParameter Description.

5 Network Impact5.1 WRFD-010686 CPC - DTX / DRX5.1.1 System Capacity

CPC-DTX/DRX maximally decreases the uplink cell load by 30% to 40% when there issufficient amount of data to transmit in the downlink and multiple UEs are continuouslydownloading data.In scenarios where the uplink cell load is the same, PC-DTX/DRX enables more UEs in theCELL_DCH state to be admitted.In addition, CPC-DTX/DRX saves the power consumption of UEs. The power-saving effectsvary depending on UEs.

5.1.2 Network PerformanceCPC-DTX/DRX decreases the data transmit frequency on the DPCCH, thereby decreasing thefrequency of uplink multipath searching and inner loop power control. In scenarios withsignificant signal fluctuation due to radio environment, the uplink of a UE easily becomes outof synchronization. As a result, the PS call drop ratio may increase slightly. The increase in thePS call drop ratio depends on the radio environment.

5.2 WRFD-010687 CPC-HS-SCCH Less operation5.2.1 System Capacity

For the initial transmission of small predefined packets, the HS-SCCH less operation featuredoes not allow the NodeB to send the HS-SCCH to the UE, decreasing downlink codes andpower consumption and increasing the capacity of downlink data services.

6 Engineering Guidelines6.1 Deployment of CPC-DTX / DRX

This section describes how to activate, verify, and deactivate the optional feature WRFD-010686CPC - DTX /DRX.

6.1.1 When to Use CPC-DTX / DRXCPC-DTX/DRX is recommended in the following scenarios:l The proportion of CPC-DTX/DRX UEs is high.l The uplink capacity needs to be increased.l The uplink DPCCH power accounts for a large proportion in the uplink RTWP.The gains produced by CPC-DTX/DRX can be obviously observed when the followingconditions are met:l The proportion of CPC-DTX/DRX UEs is higher than 20%.

NOTE

For details about how to query the proportion of CPC-DTX/DRX UEs, contact Huawei engineers.l The ratio of UEs using SRB over HS-DSCH to all UEs in the CELL_DCH state is high.

That is, the value of VS.HSDPA.SRBoH.UE.Mean.Cell/VS.CellDCHUEs is greater than20%.

l The uplink cell load over the Uu interface is high. That is, the following formula is true:VS.MeanRTWP > Background noise + Target load 2 dBwhere,Target load = 10log10 [1/(1 MaxTargetUlLoadFactor)]

l The number of HSUPA UEs in a cell is large. That is, the value of theVS.HSUPA.UE.Mean.Cell counter is greater than five.

l Enable this feature for all cells instead of for only several cells in an active set.This feature depends on SRB over HSUPA and SRB over HSDPA. It is recommended that thefollowing operations be performed:

l Obtain the models of UEs that are incompatible with CPC-DTX/DRX.During the initial stage of commercial deployment of the CPC-DTX/DRX feature, UEsthat are incompatible with this feature should be blacklisted. In this case, the blacklistedUEs cannot use the CPC-DTX/DRX feature during RAB setup, RAB modification, periodicDRD for HSPA or HSPA+ technology, and transition from other states to the CELL_DCHstate, thereby avoiding PS call drops caused by incompatibility between this feature andUEs. Before enabling the CPC-DTX/DRX feature, contact Huawei technical support toobtain the models of UEs that are incompatible with this feature.

NOTE

Before enabling the CPC-DTX/DRX feature, you need to run the SET URRCTRLSWITCH commandand select the RNC_PS_QUERY_UE_IMEI_SWITCH check box under the PROCESSSWITCH2parameter to obtain the international mobile equipment identity (IMEI) of a UE.

6.1.8 Performance MonitoringCPC-DTX/DRX can reduce the uplink cell load. The more the UEs using CPC-DTX/DRX, themore the uplink cell load is reduced.The gains produced by CPC-DTX/DRX should be observed when the values of the followingcounters basically remain unchanged:l VS.HSUPA.Thruputl VS.HSUPA.MeanBitRatel VS.HSUPA.MeanBitRate.WithDataThe method of observing the gains produced by CPC-DTX/DRX is affected by the ratio of UEsusing CPC-DTX/DRX to all UEs in the CELL_DCH state.Ratio of UEs using CPC-DTX/DRX to all UEs in the CELL_DCH state = (Sum of the value ofthe VS.CPC.DTXAct.UserNum counter for all the cells under an RNC/Number of the cells underan RNC)/VS.CellDCHUEs.RNCl VS.CPC.DTXAct.UserNum (NodeB counter): user numbers with the status of UL_DTX

and activated Configurationl VS.CellDCHUEs.RNC (RNC counter): number of UEs in the CELL_DCH state for the

RNCWhen the ratio of UEs using CPC-DTX/DRX to all UEs in the CELL_DCH state is greater thanor equal to 20%, monitor the RTWP to view the uplink cell load gains provided by this feature.To calculate the gains produced by CPC-DTX/DRX in the uplink cell load, do as follows:1. Obtain the value of the VS.MeanRTWP counter, which is recorded as RTWPon.2. Record the value of the VS.MeanRTWP counter for the cell before CPC-DTX/DRX is

enabled as RTWPoff.3. Calculate the difference between RTWPoff and RTWPon to obtain the gains produced by

CPC-DTX/DRX in the uplink cell load.When the ratio of UEs using CPC-DTX/DRX to all UEs in the CELL_DCH state is less than20%, the gains provided by CPC-DTX/DRX in the uplink cell load may be less noticeable bymonitoring the RTWP. In this case, monitor the gains in the uplink cell load in the top cellswhere the following conditions are met:l The ratio of UEs using CPC-DTX/DRX to all UEs in the CELL_DCH state in a cell

(VS.CPC.DTXAct.UserNum/VS.CellDCHUEs) is high.l The ratio of UEs using SRB over HS-DSCH to all UEs in the CELL_DCH state in a cell

is high.l The uplink cell load over the Uu interface is high.l The number of HSUPA UEs in a cell is large.The following counters for the top cells can be used to monitor the gains produced by CPC-DTX/DRX in the uplink cell load:l VS.DPCCH.10ms.POWER and VS.DPCCH.2ms.POWER

The values of the two counters decrease after CPC-DTX/DRX is enabled.l VS.HSUPA.LoadOutput.0 to VS.HSUPA.LoadOutput.25



24

The number of times the uplink cell load over the Uu interface becoming low increases,and the number of times the uplink cell load over the Uu interface becoming high decreases.

6.1.9 Parameter OptimizationIf CPC-DTX/DRX increases the PS call drop ratio, perform the following operations to checkwhether call drops occur on a type of UE in a certain scenario:1. Calculate the rate of RABs abnormally released for UEs processing PS services by using

the following formula to check whether most of call drops occur on these UEs:Rate of RABs abnormally released for UEs processing PS services =VS.RAB.AbnormRel.PS/(VS.RAB.AbnormRel.PS + VS.RAB.NormRel.PS)

2. Check whether a type of UE experiences call drops in a certain scenario.If a type of UE enabled with CPC-DTX/DRX easily experiences call drops in a certainscenario, this type of UE is incompatible with CPC-DTX/DRX in such scenarios. In thiscase, run the RNC MML command ADD UIMEITAC and select theSPECUSER_CPC_DTX_DRX_DISABLED_SWITCH check box under the SpecialUser Function Switch3 parameter to blacklist these UEs.

3. Check whether call drops frequently occur in the following scenarios: DRD, hardhandovers, or state transitions from CELL_FACH to CELL_DCH (F2D for short) or fromCELL_PCH/URA_PCH to CELL_DCH (P2D for short).If yes, the NodeB must obtain the start time of the period specified by theDtxDrxEnablingDelay parameter upon radio link set-up in the preceding scenarios. If theNodeB does not obtain the start time, it will activate the CPC at a time different from thetime the UE activates the CPC. As a result, a call drop occurs. To enable the NodeB toobtain the start time upon radio link setup in the preceding scenarios, run the MMLcommand SET UALGORSVPARA and set CPC_OPT_FOR_RLSETUP_SWITCH toON.

4. Check whether call drops are caused by link synchronization failures.If link synchronization failures cause call drops and the number of UEs in the CELL_DCHstate and the number of UEs configured with CPC are small, run the MML command SETNODEBRSVDPARA and select the RSVDBIT8 check box under theNODEBRSVDPARA1 parameter to enable the CPC link synchronization enhancementfunction. This function enhances the link synchronization performance in the CPC mode.

If network KPIs continue deteriorating after this type of UE is blacklisted, it is recommendedthat the parameters for the CPC-DTX/DRX feature be reconfigured. For example, set theDtxCycle2 parameter to 5 to reduce the DRX and DTX periods. During parameter setting, therelationships between parameters must meet the requirements specified in 3GPP. For detailsabout the relationships between parameters, see section 8.6.6.39 "DTX-DRX information (FDDonly)" in 3GPP TS 25.331 V9.0.0.

6.2 Deployment of CPC-HS-SCCH less operationThis section describes how to activate, verify, and deactivate the optional feature WRFD-010687CPC - HS-SCCH less operation.



25

6.2.1 When to Use CPC-HS-SCCH less operationCPC-HS-SCCH less operation is recommended when the following conditions are met:l The proportion of CPC HS-SCCH less operation UEs is higher than 20%.l The HS-SCCH usage is high in a cell. For example, the HS-SCCH usage is considered high

when the value of the VS.ScchCodeUtil.Mean.Data counter exceeds 50%.

6.2.2 Information to Be CollectedThe following table lists the counter information to be collected before the feature is enabled.

Counter name DescriptionVS.DataTtiRatio.Mean Ratio of the time when at least one HSDPA user has

data to transmit in the queue bufferVS.HSDPA.InactiveDataTtiRatio.Mean

Average ratio of the time when at least one HSDPAuser has data to transmit in the buffer but no HSDPAuser transmits data at the physical layer

VS.HSDPA.2ScchCodeRatio The time ratio of only using two HS-SCCH codes forcell

VS.HSDPA.3ScchCodeRatio The time ratio of only using three HS-SCCH codes forcell

VS.HSDPA.4ScchCodeRatio The time ratio of only using four HS-SCCH codes forcell

VS.ScchCodeUtil.Mean.Data Average usage of HS-SCCH code resources when atleast one HSDPA user has data to transmit in thequeue buffer

The VS.ScchCodeUtil.Mean.Data counter provides the average usage of HS-SCCH coderesources. CPC-HS-SCCH less operation is recommended when the value of this counter is high.The value of VS.DataTtiRatio.Mean minus VS.HSDPA.InactiveDataTtiRatio.Mean indicatesthe ratio of duration when there is data transmission at the physical layer to a measurement periodin a cell. You can obtain the usage of HS-SCCH code resources on a specific SCCH channel bymonitoring counters VS.HSDPA.2ScchCodeRatio, VS.HSDPA.3ScchCodeRatio, andVS.HSDPA.4ScchCodeRatio. CPC-HS-SCCH less operation is recommended when the valuesof these counters are high.
