DC-HSDPA 2 Overview



2-1

2 Overview

Similar to Long Term Evolution (LTE), the HSPA technology is also influenced by the multi-carrieraggregations. The performance and throughput of HSPA can be improved by using more bandwidth

provided by multi-carriers. The throughput of end users can be double or more as compared withsingle-carrier HSPA.

In versions earlier than 3GPP Release 8, a UE used only a single carrier for HSDPA transmission. Theuse of a single carrier for HSDPA transmission is referred to as SC-HSDPA in this document.

3GPP Release 8 introduced DC-HSDPA. DC-HSDPA uses two adjacent carriers for the HSDPAtransmission of a UE, which doubles UE downlink throughput.

The requirements of DC-HSDPA are listed in Table 2-1.

Table 2-1 Requirements of the DC-HSDPA

Item Requirement

CN None

RNC The RNC needs to support downlink enhanced L2.

The RNC provides the radio bearer scheme for DC-HSDPA.

NodeB DC-HSDPA requires NodeB to support MAC-ehs. A single MAC-ehs entity supports HS-DSCHtransmission in more than one cell served by the same Node-B (FDD only).

UE In 3GPP Release 8, HS-DSCH UE categories 21, 22, 23, and 24 are added to supportDC-HSDPA. In 3GPP Release 9 or later, more HS-DSCH UE categories support DC-HSDPA.

DC-HSDPA 3 Basic Principle



3-1

3 Basic Principle

3.1 Overview

DC-HSDPA allows a UE to set up HSDPA connections with two inter-frequency co-coverage cells. In thedownlink, the UE can simultaneously receive data over HS-DSCHs in the two cells. In the uplink, the UEusing the DCH or SC-HSUPA transmits data only in the primary cell. This document describes only theDC-HSDPA UEs whose uplink connections are established on the DCH or SC-HSUPA. For details aboutthe DC-HSDPA UEs whose uplink connections are established on the DC-HSUPA, see DC-HSUPAFeature Parameter Description.

Figure 3-1 shows an example of the uplink and downlink data transmission for a DC-HSDPA UE.

Figure 3-1 Example of the uplink and downlink data transmission for a DC-HSDPA UE

The two cells (primary cell and secondary cell) of DC-HSDPA follow the following restrictions:

The two cells belong to the same sector of a NodeB and are inter-frequency same-coverage cells.

The two cells are in the same downlink resource group of a NodeB.

The two cells operate on adjacent carriers with a frequency spacing less than or equal to 5 MHz in thesame frequency band.

The two cells have the same timing (Tcell).

The two cells support HSDPA and enhanced L2.

The two cells belong to the same operator.

The dual cell transmission only applies to HSDPA physical channels.

DC-HSDPA improves the throughput and delay of users in the whole cell even at the cell edge.Theoretically, DC-HSDPA with 64QAM provides a downlink peak data rate of 42 Mbit/s, which is twicethe peak rate provided by 64QAM.

3-3

Figure 3-3 Primary and secondary cells configured with the same types of common channels

If the primary cell is configured with all the common channels shown in Figure 3-3, and if the secondarycell is configured with the HS-PDSCH, HS-SCCH, and P-CPICH, the secondary cell cannot provideservices for SC-HSDPA and R99 users. Currently, Huawei DC-HSDPA does not support suchconfigurations.

3.2.2 DC-HSDPA Cell Groups

DC-HSDPA requires two inter-frequency co-coverage cells. The two cells are configured in a DC-HSDPAcell group on the NodeB side as follows: Run the NodeB MML command ADD DLDUALCELLGRP toadd the two DC-HSDPA cells to the DC-HSDPA cell group.

The NodeB reports the information about cells in each DC-HSDPA cell group to the RNC over the Iubinterface. The RNC selects a primary cell and a secondary cell for a DC-HSDPA UE based on thereceived cell information. For details, see section 4.5.1 "RAB DRD."

NOTE

The Tcell parameter must be set to the same value for the cells of a DC-HSDPA group.

3.3 Channel Mapping

3.3.1 Overview

Figure 3-4 Channel mapping of DC-HSDPA

A DC-HSDPA UE receives two HS-DSCH transport channels from two cells of the same NodeB. EachHS-DSCH is mapped to one HS-SCCH and several HS-PDSCH physical channels.

The dedicated physical control channels DPCCH and DPCH/F-DPCH in the uplink and downlink arecarried on the primary cell.

3.3.2 HS-SCCHIn versions earlier than 3GPP Release 8, a UE can monitor a maximum of four HS-SCCHs at the sametime, according to 3GPP TS 25.331. In DC-HSDPA cell group, the HS-SCCHs on the primary cell areindependent of those on the secondary cell. A UE can monitor a maximum of six HS-SCCHs at the sametime. In each cell, the UE can monitor a maximum of three HS-SCCHs at the same time.

There are three types of HS-SCCH, type 1 for common use, type 2 for HS-SCCH Less Operation, andtype 3 for MIMO. DC-HSDPA uses only HS-SCCH type 1. DC-HSDPA with HS-SCCH Less Operationuses HS-SCCH type 2.

HS-SCCH Less Operation applies only to the primary cell.

3.3.3 HS-DPCCHThe UE gives feedback on the CQIs and HARQ ACK/NACK about two cells on the HS-DPCCH channelto the primary cell. The HS-DPCCH uses a new frame format that enables it to carry CQI and HARQ ACK/NACK information of the two cells in a Transmission Time Interval (TTI).

3.4 UE Categories

In 3GPP Release 8, HS-DSCH UE categories 21, 22, 23, and 24 are added to support DC-HSDPA, aslisted in Table 3-1. In 3GPP Release 9 or later, more HS-DSCH UE categories support DC-HSDPA. Fordetails about HS-DSCH UE categories, see 3GPP TS 25.306.

When a UE does not use DC-HSDPA after accessing a DC-HSDPA cell, the RNC performs fallback onthe UE if the UE belongs to a certain HS-DSCH category. For details about HS-DSCH categories thatsupport fallback in such a circumstance, see 3GPP TS 25.331.

The peak rate can reach 42.192 Mbit/s (= 2 x TB_Size/TTI = 2 x 42192/2) at the MAC layer, supportedby the CN.

3.5 NodeB MAC-ehs

DC-HSDPA requires the NodeB to support MAC-ehs. A single MAC-ehs entity supports HS-DSCHtransmission in more than one cell served by the same NodeB (FDD only). Queues of a DC-HSDPA UEare common for the two cells. The scheduler in the NodeB arranges the data transmission of queues onthe two cells. DC-HSDPA transmissions can be regarded as independent transmissions over twoHS-DSCH channels. There will be a separate HARQ entity on each HS-DSCH channel, that is, oneHARQ process per TTI for single carrier transmission and two HARQ processes per TTI for dual carriertransmission.

MAC-ehs selects Transport Format and Resource Combination (TFRC) for the MAC-ehs Protocol DataUnits (PDUs) of each cell independently based on the available resources of the cells and the CQI

reported by the UE.

3.6 Impact on Interfaces

3.6.1 Overview

To support DC-HSDPA, new Information Elements (IEs) are added to signaling messages.



WCDMA RAN




3-7

UEs and NodeBs can report their capacity of DC-HSDPA to the RNC through the Iub and Uu interfaces.The RNC instructs cells to set up or reconfigure radio links with DC-HSDPA through the Iub interface.The RNC instructs UEs to set up or reconfigure radio bearers with DC-HSDPA through the Uu interface.

3.6.2 Impact on Iub

When a cell receives the AUDIT REQUEST message or when a new cell is set up or a cell capability ischanged, the NodeB reports the cell capability to the RNC in Audit Response message or ResourceState Indication message

When a cell supports DC-HSDPA, the NodeB sets the Multi Cell Capability Info IE to Multi CellCapable for the cell in Audit Response and sends the message to the RNC.

If the cell is a primary serving cell, all the possible secondary serving cells in the same sector must belisted in the Possible Secondary Cell List IE.

When the RNC instructs a cell to set up a radio link with DC-HSDPA, the information of the secondaryserving cell is added to the Radio Link Setup procedure or Radio Link Addition procedure.

The Additional HS Cell Information RL Setup IE is added to the Radio Link SetupRequest/Response/Failure messages and Radio Link Addition Request/Response/Failure messages toindicate the usage of DC-HSDPA and associated parameters.

3.6.3 Impact on Uu

In the RRC CONNECTION REQUEST message, the Multi cell support IE is added to indicate the UEcapability of supporting multiple cells.

In the RRC Connection Setup Complete and UE Capability Information message, the Physical ChannelCapability IE is extended to indicate the UE capability of DC-HSDPA.

The Downlink secondary cell info FDD IE in the following signaling messages indicates the usage of

secondary serving cell and related parameters:

DC-HSDPA 4 Technical Description



4-1

4 Technical Description

4.1 Overview

This document describes only the functions that are different from those of SC-HSDPA.

These functions are as follows:

Radio Bearers

State transition

Mobility management

Load control

Scheduling

For details about other functions, see the HSDPA Feature Parameter Description.

4.2 Radio BearersWhen the downlink transport channel HS-DSCH is selected for streaming or BE services or combinedservice with streaming or BE, DC-HSDPA can be applied. When there is only a CS service, PSconversational service, IMS signaling, or SRB signaling, DC-HSDPA is not applied because of smalltraffic volume. You need to configure DC-HSDPA on both the NodeB and RNC sides.

On the NodeB side

You must configure DC-HSDPA cells. For details about how to configure DC-HSDPA cells, see section3.2 "DC-HSDPA Cells."

On the RNC side

− Select CFG_HSDPA_DC_SWITCH in the RNC-level parameter CfgSwitch to enable services to be

carried on DC-HSDPA. The CfgSwitch parameter is in the SET UCORRMALGOSWITCH command.

− Select DC_HSDPA in the cell-level parameter HspaPlusSwitch to enable DC-HSDPA in the cell.The HspaPlusSwitch parameter is set in the ADD UCELLALGOSWITCH and MODUCELLALGOSWITCH commands.

− Set MIMO64QAMorDcHSDPASwitch in the SET UFRC command to DC_HSDPA to selectDC-HSDPA as the preferential HSPA+ technology for the cell.

The Continuous Packet Connectivity (CPC) function can be enabled in the DC-HSDPA cells with thefollowing limitations:

CPC DTX is applicable to primary cell only because there will be no uplink control channel for theDC-HSDPA UE on secondary cell

CPC HS-SCCH Less Operation is applicable to primary cell only and is not applicable to secondarycell.

CPC DRX for a DC-HSDPA UE on two carriers is similar to that for a UE on a single cell.

Only UEs complying with 3GPP Release 9 and later support DC-HSDPA+MIMO. Table 4-1 describes theimplementation of DC-HSDPA+MIMO in Huawei products. For details about DC-HSDPA+MIMO, seeHSPA Evolution Feature Parameter Description.

RAN13.0 Yes 2 Yes

RAN14.0 Yes 2 Yes

64QAM can be enabled in one or both cells in the DC-HSDPA cell group. DC-HSDPA and 64QAM canbe used at the same time. When both cells in a DC-HSDPA group have 64QAM enabled, the peakdownlink rate can reach 42 Mbit/s.

When a file is being downloaded, the TCP acknowledgement is sent in the uplink. The higher the rate ofdownload is, the larger the bandwidth is required in the uplink. If the download rate reaches up to 42Mbit/s, the uplink rate of TCP acknowledgement is much higher than 384 kbit/s, the highest supported bythe DCH. HSUPA bearer is required to provide high bandwidth in the uplink to transmit TCPacknowledgement without delay. The downlink rate of 42 Mbit/s per user can be supported only whenHSUPA is used.

4.3 State Transition

DC-HSDPA UEs only support the CELL_DCH state. After DC-HSDPA UEs transition to other states, theycannot be carried on DC-HSDPA. DC-HSDPA UEs can perform state transition only in the primary cell.

When a UE supporting DC-HSDPA transitions from the CELL_FACH, CELL_PCH, or URA_PCH state tothe CELL_DCH state, the RNC establishes a DC-HSDPA radio bearer (RB) for the UE. After the statetransition is complete, the RNC performs RAB DRD to select an appropriate DC-HSDPA group for theUE. For details, see section 4.5.1 "RAB DRD."

NOTE

DC-HSDPA RB refers to the HSDPA RB that has DC-HSDPA enabled.

The state transition trigger threshold for DC-HSDPA UEs is the same as that for SC-HSDPA UEs. Fordetails, see State Transition Feature Parameter Description.

4.4 Mobility Management

4.4.1 Overview

The introduction of DC-HSDPA has no impact on handover measurement triggering and handoverdecision processes. During a handover, however, the RNC needs to decide whether DC-HSDPA is usedafter the handover if the target cell supports DC-HSDPA, or whether non-DC-HSDPA is used after thehandover if the target cell does not support DC-HSDPA.

This section describes only the mobility management of DC-HSDPA. For other information abouthandover, see the Handover Feature Parameter Description.

4.4.2 Measurement Control

When DC-HSDPA is enabled, the RNC maintains the active set only in the primary cell.

The intra-frequency measurement control for DC-HSDPA UEs is the same as that for SC-HSDPA UEs.

DC-HSDPA UEs can perform inter-frequency measurement in the following modes:

Compressed mode

http://localhost/var/www/apps/conversion/tmp/scratch_6/State%20Transition.htm



http://localhost/var/www/apps/conversion/tmp/scratch_6/Handover.htm







WCDMA RAN




4-3

The inter-frequency measurement control for DC-HSDPA UEs in compressed mode is the same asthat for SC-HSDPA UEs in compressed mode.

Non-compressed mode

DC-HSDPA UEs perform inter-frequency measurement in non-compressed mode when all of the

following conditions are met:

− CMP_UU_ADJACENT_FREQ_CM_SWITCH in the CmpSwitch parameter for the SETUCORRMALGOSWITCH command is selected.

When CMP_UU_ADJACENT_FREQ_CM_SWITCH is selected, the UE can perform inter-frequencymeasurement in non-compressed mode on frequencies spaced less than or equal to 5 MHz from theoperating frequency of the UE. For a DC-HSDPA network, it is recommended that this switch beturned off, because the UE currently cannot report whether it is allowed to use the non-compressedmode for frequencies of neighboring cells within 5 MHz from the current frequency.

− The value of the following IE in the RRC CONNECTION SETUP COMPLETE message sent by theUE is TRUE: "UE radio access capability" IE > "Measurement capability" IE > "Adjacent frequencymeasurements without compressed mode" IE.

− If UEs are performing DC-HSDPA services, the UE performs inter-frequency measurement only inthe cells operating on the same frequency as the secondary cell and the frequency is spaced lessthan or equal to 5 MHz from the operating frequency of the current cell.

− If UEs are not performing DC-HSDPA services, the UE performs inter-frequency measurement in thecells that meet the following conditions:

The cells that operate on the same frequency at the same frequency band as the current cell.

The cells that operate on frequencies whose center frequencies are spaced less than or equal to 5MHz away from the center frequency of the current cell.

All cells to be measured operate on the same frequency.

4.4.3 Intra-Frequency Handover

When receiving a measurement report indicating that the signal quality of a DC-HSDPA cell is better thanthat of the serving cell (a DC-HSDPA cell), the RNC decides whether to perform a DC-HSDPA handoverto the target cell:

If the admission to the target cell is allowed and the radio link configuration is successful, the RNCperforms the handover.

If the admission to the target cell is allowed but the radio link configuration is unsuccessful, the RNCreconfigures the service on SC-HSDPA and then performs an SC-HSDPA handover.

If the admission to the target cell is not allowed, the RNC reconfigures the service on the DCH andperforms a DCH handover:

−

If the DCH handover is allowed, the RNC performs the handover.− Otherwise, the RNC does not perform the handover.

4.4.4 Inter-Frequency Handover

During an inter-frequency handover, the DC-HSDPA UE needs to measure the signal quality of theprimary cell and its neighboring cells. If the secondary cell is a neighboring cell of the primary cell, theDC-HSDPA UE also needs to measure the signal quality of the secondary cell. The inter-frequencyhandover process for DC-HSDPA UEs is the same as that for SC-HSDPA UEs. For details about theinter-frequency handover, see Handover Feature Parameter Description.

4.4.5 Handover from a DC-HSDPA Cell to a Non-DC-HSDPA Cell

When receiving a measurement report from a DC-HSDPA UE indicating that the signal quality of aninter-frequency non-DC-HSDPA cell is better than that of the serving cell (a DC-HSDPA cell), the RNCinitiates an RB reconfiguration procedure to make the service be carried on the DCH or HSDPA andmeanwhile performs a handover.

When receiving a measurement report carrying the signal quality of intra-frequency non-DC-HSDPAcells, the RNC performs different operations in different scenarios. Details are as follows:

If an intra-frequency non-DC-HSDPA cell in the active set reports event 1D,

− The RNC initiates an RB reconfiguration procedure to make the service be carried on the DCH orHSDPA and meanwhile initiates a serving cell change procedure whenCMP_UU_SERV_CELL_CHG_WITH_RB_MOD_SWITCH in the CmpSwitch parameter is selected.

− The RNC initiates an RB reconfiguration procedure to make the service be carried on the DCH orHSDPA and then initiates a serving cell change procedure whenCMP_UU_SERV_CELL_CHG_WITH_RB_MOD_SWITCH in the CmpSwitch parameter is

deselected. If an intra-frequency non-DC-HSDPA cell outside the active set reports event 1D,

− The RNC initiates an RB reconfiguration procedure to make the service be carried on the DCH orHSDPA and then initiates an active set update procedure with serving cell change whenCMP_UU_SERV_CELL_CHG_WITH_ASU_SWITCH in the CmpSwitch parameter is selected.

− The RNC initiates an RB reconfiguration procedure to make the service be carried on the DCH orHSDPA, initiates an active set update procedure, and then initiates a serving cell change procedurewhen CMP_UU_SERV_CELL_CHG_WITH_ASU_SWITCH in the CmpSwitch parameter isdeselected.

The CmpSwitch parameter is in the SET UCORRMALGOSWITCH command.

4.4.6 Handover from a Non-DC-HSDPA Cell to a DC-HSDPA Cell

When receiving a measurement report indicating that the signal quality of a DC-HSDPA cell is better thanthat of the serving cell (a non-HSDPA cell), the RNC performs a handover after which the HSPA+technologies supported by both the source cell and the target cell are used in the target cell. If suchHSPA+ technologies are ranked lower than some HSPA+ technologies supported by both the target celland the UE, the ChannelRetryHoTimerLen timer is started after the handover. When the timer expires,the RNC tries to reconfigure the traffic radio bearer (TRB) and signaling radio bearer (SRB) to enablethem to support the higher-ranked HSPA+ technologies. If the reconfiguration fails, the RNC starts theretry timer (ChannelRetryTimerLen ) for periodic retry attempts.

The HSPA+ technologies that can be retried are specified by the parameter RetryCapabil i ty in the SET

UFRC command.The ChannelRetryHoTimerLen and ChannelRetryTimerLen commands are set using the SETUCOIFTIMER command.

4.4.7 Inter-RAT Handover

The inter-RAT handover process for DC-HSDPA UEs is the same as that for SC-HSDPA UEs. For details

about the inter-RAT handover, see Handover Feature Parameter Description.

After a UE is handed over to a DC-HSDPA cell from a cell belonging to another RAT, the UE is carried on

the HSDPA. The RNC starts a retry timer as soon as the handover is complete. When the timer expires,

the RNC initiates an RB reconfiguration procedure to make the UE carried on the DC-HSDPA or a higher

HSPA+ technology. If the reconfiguration fails, the RNC starts the retry timer for periodic DRD.

The ChannelRetryTimerLen parameter in the SET UCOIFTIMER command specifies the retry timer.

4.4.8 Handover Between RNC

The current version does not support the handover between different RNCs for DC-HSDPA users.

During the handover, if the target cell is from different RNC, the DC-HSDPA user falls back to SC-HSDPAand then the handover is performed.

Upon completion of the handover, if DC-HSDPA is included in HSPA technologies that can be retried byUEs (that is, DC-HSDPA under the RetryCapabil i ty parameter is turned on) and the handover target cellsupports DC-HSDPA, the RNC will attempt to switch the services on DC-HSDPA RABs.

4.5 Load Control

4.5.1 RAB DRD

During the RAB setup or state transition from CELL_FACH to CELL_DCH, the RNC performs DRDs toselect a primary cell and a secondary cell for DC-HSDPA UEs. This section describes the DRD forDC-HSDPA UEs. For more details about DRD, see Directed Retry Decision Feature ParameterDescription.

1. The RNC selects cells that meet the quality requirements of inter-frequency DRD as candidate cells.

For details about the quality requirements of inter-frequency DRD, see section "Inter-Frequency

multiple candidate cells all have the highest HSPA+ technological satisfaction or if DRD for HSPA+technological satisfaction is disabled, proceed to step (c).

For details about how to select candidate cells based on the HSPA+ technological satisfaction, seesection "Inter-Frequency DRD for Technological Satisfaction" in Directed Retry Decision Feature

Parameter Description. (c) When DRD for service steering is enabled, the RNC selects the candidate cell with the highestservice priority as the primary cell and proceeds to step 3. If multiple candidate cells all have thehighest service priority or if DRD for service steering is disabled, proceed to step (d).

For details about how to select candidate cells based on the service priority, see section "ServicePriority-based Cell Selection."

(d) When DRD for load balancing is enabled, the RNC selects the candidate cell with the lightestdownlink load based on downlink load balancing. For a DC-HSDPA cell, the RNC considers thedownlink load of the corresponding DC-HSDPA group, not the downlink load of the DC-HSDPA cell.Therefore, the RNC selects at least two cells in the same DC-HSDPA group as candidate cells. Then,the RNC selects the cell with the lightest load as the primary cell based on uplink load balancing andproceeds to step 3.

For details about how to select cells based on downlink load balancing, see "Downlink Load-basedCell Selection." For details about how to select cells based on uplink load balancing, see "UplinkLoad-based Cell Selection."

3. The RNC selects the other cell in the DC-HSDPA group to which the primary cell belongs as thesecondary cell. The DRD procedure is complete. Then, the RNC performs call admission control(CAC). For details, see section "Inter-Frequency DRD" in Directed Retry Decision Feature ParameterDescription.

NOTE

The HSPA technological satisfaction of DC-HSDPA cells is the same as that of SC-HSDPA cells. When all of the precedingDRD functions are disabled, the RNC instructs the UE to access the cell with the highest HSPA technological satisfaction.If the access fails, the RNC randomly selects a cell from candidate cells for the UE. If the cell supports DC-HSDPA, the

cell serves as the primary cell, and the other cell in the DC-HSDPA group serves as the secondary cell. If the cell does notsupport DC-HSDPA, the UE accesses the cell with the highest technology supported by the cell.

Service Priority-based Cell Selection

The service priority-based cell selection for DC-HSDPA UEs is the same as the target cell selection forSC-HSDPA UEs.

When multiple candidate cells support the same HSPA+ technologies, the RNC determines the servicepriorities of cells based on the uplink and downlink service bearers for the UE if DRD for service steeringis enabled. The RNC then ranks candidate cells according to service priority and selects the cell with thehighest service priority as the candidate cell.

The RNC uses HSDPA as the downlink service bearer for DC-HSDPA UEs.

If the requested service is combined services, the RNC uses the RAB with the highest priority for ranking.In addition, the selected cell must support all services in the combined services. For details about thepriority of a RAB, see Load Control Feature Parameter Description.

Table 4-2 lists the reference service priorities for different service bearers.

For details about how to select cells based on the service priority, see section "Inter-Frequency DRD forService Steering" in Directed Retry Decision Feature Parameter Description.

Downlink Load-based Cell Selection

The DRD for load balancing function for DC-HSDPA UEs is performed based on the number of powerresources available in the downlink and is basically the same as the downlink load balancing-basedDRD for SC-HSDPA UEs. The only difference is that the RNC considers the load of the DC-HSDPAgroup to which the candidate cell belongs when performing DRD based on load balancing forDC-HSDPA UEs.

For details about the downlink load balancing-based DRD, see section "Inter-Frequency DRD for LoadBalancing" in Directed Retry Decision Feature Parameter Description.

Uplink Load-based Cell Selection

DC-HSDPA UEs have uplink channels only in the primary cell. If a large number of DC-HSDPA UEs usea cell as the primary cell, the uplink load of the cell increases, and the uplink coverage deteriorates. The

uplink load-based cell selection function helps balance the uplink load between two carriers.

If the uplink load balancing switch ULLdbDRDSwitchDcHSDPA is set to OFF, the RNC randomlyselects a cell from candidate cells as the primary cell.

If this switch is set to ON, the RNC selects the cell with the lightest uplink load as the candidateprimary cell.

The RNC performs the uplink load balancing between candidate cells based on the equivalent number ofusers (ENUs) in the uplink.

The uplink load balancing-based DRD for DC-HSDPA is as follows:

1. If the UE initiates an RRC connection request in a non-candidate cell, the RNC selects the cell with

the lightest uplink load from candidate cells as the primary cell.2. In other circumstances, the RNC checks whether the remaining uplink ENUs of the current cell are

greater than the value of the ULLdbDRDLoadRemainThdDCHSDPA parameter.

If the remaining uplink ENUs of the current cell are greater than the value of theULLdbDRDLoadRemainThdDCHSDPA parameter, the RNC selects the current cell as the primarycell.

If the remaining uplink ENUs of the current cell are less than or equal to the value of theULLdbDRDLoadRemainThdDCHSDPA parameter, the RNC calculates the difference between theremaining uplink ENUs of the candidate primary cell and that of the current cell.

− If the difference is greater than the value of ULLdbDRDOffsetDcHSDPA , the RNC selects thecandidate primary cell as the primary cell.

− Otherwise, the RNC selects the current cell as the primary cell.

After selecting the primary cell, the RNC selects the other cell in the same DC-HSDPA group as thesecondary cell.

4.5.2 Call Admission Control

Overview

In terms of Call Admission Control (CAC) based on the code resource, CE resource, or Iub resource,DC-HSDPA CAC is not changed, compared with SC-HSDPA CAC.

In terms of CAC based on the DL power or equivalent number of users (ENU), DC-HSDPA CAC ischanged, that is, the resources of the DC-HSDPA cell group need to be considered.

CAC Based on the DL Power

Figure 4-2 shows the resource allocation in the two cells of a DC-HSDPA cell group. In this figure, the DLpower is taken as an example.

Figure 4-2 DL power of a DC-HSDPA cell group

The variables in Figure 4-2 are described as follows:

Pmax: maximum DL power of a cell

Pnon-HSPA: DL power used for non-HSPA UEs in a cell

GBPSC-H: DL power required by the HS-PDSCHs to provide GBRs for SC-HSDPA UEs in a cell.

GBPDC-H: DL power required by the HS-PDSCHs to provide GBRs for the DC-HSDPA UEs in theDC-HSDPA cell group.

For a DC-HSDPA UE, the RNC performs CAC based on the total DL power margin of the DC-HSDPA cellgroup because the UE can use the DL power margin of any of the two cells after the admission.

For a non-DC-HSDPA UE, the RNC performs CAC based on the total DL power of the serving cell minusthe DL power used for the existing non-DC-HSDPA UEs in this cell. If the admission is successful, theRNC continues to perform the CAC based on the total DL power margin of the DC-HSDPA cell group.

CAC Based on the ENU

The CAC based on the Equivalent Number of Users (ENU) is similar to CAC based on the DL power.



WCDMA RAN




4-11

The calculation of the scheduling priority of a DC-HSDPA queue needs to consider different CQIs and Uurates of the two carriers. In the proportional fair (PF) algorithm and enhanced proportional fair (EPF)algorithm, R/r used for DC-HSDPA is different from that used for SC-HSDPA:

For SC-HSDPA, R represents the throughput corresponding to the CQI reported by the UE for this

carrier, and r represents the throughput currently achieved by the UE. A greater R/r value indicates ahigher scheduling priority.

For DC-HSDPA, R represents the throughput corresponding to the CQI reported by the UE for thiscarrier, and r represents the total throughput currently achieved by the UE on the two carriers. Agreater R/r value indicates a higher scheduling priority.

4.7 Activating or Deactivating Secondary Cell

This section describes the feature WRFD-010713 Traffic-Based Activation and Deactivation of theSupplementary Carrier In Multi-carrier.

The NodeB periodically monitors the traffic volume of a UE and decides whether to activate or deactivatethe secondary cell in the DC-HSDPA/DC-MIMO cell group through HS-SCCH order.

If the throughput at the MAC-ehs layer is lower than 100 kbit/s and the data in an MAC-ehs queue is80% likely to be completely sent within a short time, the NodeB instructs the UE to deactivate thesecondary cell.

If the throughput at the MAC-ehs layer is higher than 400 kbit/s and the data in an MAC-ehs queue is20% likely to be completely sent within a short time, the NodeB instructs the UE to activate thesecondary cell.

The preceding thresholds are not configurable.

The deactivation neither changes a DC-HSDPA cell to a non-DC-HSDPA cell nor changes the HS-DSCHUE category. After deactivation, the NodeB regards the UE as a SC-HSDPA UE, and after activation, the

NodeB regards the UE as a DC-HSDPA UE.

The function is controlled by the SECCELLACTDEASW switch in the NodeB MML command SETMACHSPARA.

The activation or deactivation is applicable to the UEs configured with DC-HSDPA, DC-MIMO, orDB-HSDPA in the downlink and to those configured with DCH or SC-HSUPA in the uplink. The function isnot applicable to DC-HSUPA because DC-HSUPA depends on DC-HSDPA.

The activation or deactivation of the UE takes effect after 12 timeslots when the UE receives theHS-SCCH order. The activation or deactivation of the NodeB takes effect immediately after the NodeBreceives an ACK of HS-SCCH order from the UE. If the NodeB receives an DTX from the UE, the NodeBretransmits or discards the HS-SCCH order.

DC-HSDPA 6 Impact on the Network



6-1

6 Impact on the Network

6.1 DC-HSDPA

6.1.1 System Capacity

DC-HSDPA provides the following benefits:

Increases single-user downlink peak throughput. DC-HSDPA together with 64QAM pushes thesingle-user downlink peak throughput up to 42 Mbit/s.

Reduces the transmission delay of burst services and improves user experience.

DC-HSDPA UEs have the HS-DPCCH only in the primary cell, and therefore the uplink load of theprimary cell is slightly higher than that of SC-HSDPA cells.

DC-HSDPA UEs consume one channel element (CE) more than SC-HSDPA UEs.

6.1.2 Network Performance

DC-HSDPA affects cell uplink load and cell downlink load.

Impact on cell uplink load

Compared with SC-HSDPA UEs, DC-HSDPA UEs need to demodulate the signals in the primary andsecondary cells and need to report the feedback about both cells in the primary cell. The transmitpower of a DC-HSDPA UE on the HS-DPCCH is about 2 dB higher than that of SC-HSDPA UEs. Theuplink load of the primary cell is increased as a result.

Impact on cell downlink load

− For cells that have the same HSDPA service priority, DC-HSDPA does not significantly affect the

downlink load.− For cells that have different HSDPA service priorities, DC-HSDPA increases the downlink load of thecell with lower HSDPA service priority. The load increase is related to the proportion of UEssupporting DC-HSDPA and service model.

6.2 Traffic-Based Activation and Deactivation of theSupplementary Carrier In Multi-carrier

6.2.1 System Capacity

When there are a large number of multi-carrier HSDPA users (for example, DC-HSDPA users) anddownlink traffic is light, deactivating the supplementary carrier reduces uplink load in the cell served by

the primary carrier and increases the uplink capacity. This is demonstrated in the increase of the celluplink throughput or admitted number of users. For example, in a cell enabled with DC-HSDPA, theuplink load is reduced by 5% to 10% after the supplementary carrier is deactivated when the penetrationrate of DC-HSDPA users reaches 100%.

6.2.2 Network Performance

This feature deactivates the supplementary carrier for DC-HSDPA or DC-HSDPA+MIMO users with lowtraffic volume, reducing the radio resources available for these users. As a result, the service delay ofthese users may rise.

DC-HSDPA 7 Engineering Guidelines



7-1

7 Engineering Guidelines

7.1 WRFD-010696 DC-HSDPA

7.1.1 When to Use DC-HSDPA

DC-HSDPA is recommended for urban areas where at least two cells operate on frequencies at thesame frequency band and the spectrum resources are not limited.

In urban areas where the network capacity is not limited, DC-HSDPA provides more benefits if mostservices on the live network are burst services. Details are as follows:

Compared with SC-HSDPA, DC-HSDPA doubles the single-user throughput in the cell center and at thecell edge. DC-HSDPA also reduces the transmission delay and improves user experience. However,when the number of UEs performing data transmission increases, the downlink load increases, and as aresult the feature benefits in single-user throughput and cell throughput decrease.

DC-HSDPA can also be deployed in networks with limited capacity and high downlink load, but thefeature benefits are less noticeable.

DC-HSDPA is also recommended for suburban and rural areas where the network capacity is not limited.In such scenarios, DC-HSDPA increases the peak data rate for users and noticeably improves theexperience of users at cell edges.

7.1.2 Required Information

Before feature deployment, operators need to collect the following information:

Proportion of UEs supporting DC-HSDPA

A higher proportion of UEs supporting DC-HSDPA results in better system throughput gains.The VS.HSDPA.UE.Mean.CAT21.24 and VS.HSDPA.UE.Mean.CAT25.28 counters measure theaverage numbers of DC-HSDPA UEs.

Uplink capabilities

If dedicated channels (DCHs) are used in the uplink, the downlink peak rates for DC-HSDPA users arerestricted, resulting in decreased gains. HSUPA is recommended in the uplink for DC-HSDPA.

For details about how to check whether HSUPA is enabled in the uplink, see HSUPA FeatureParameter Description.

Bandwidth over the Iub interface

If the bandwidth over the Iub interface is inadequate, DC-HSDPA cannot yield notable gains. Anappropriate bandwidth is required over the Iub interface.

DC-HSDPA provides single-user downlink peak throughput of 42 Mbit/s. The minimum bandwidth overthe Iub interface is 50 M in IP transmission and is 55 M in ATM transmission considering the Iubtransmission efficiency. The actual bandwidth required over the Iub interface is greater than 50 Mbecause there are R99 users on the live network. The actual bandwidth required over the Iub interfacemust be calculated based on network planning and network optimization.

Packet loss rate on the core network

If the core network has a high packet loss rate, gains provided by DC-HSDPA decrease duringsingle-thread FTP sessions. An appropriate packet loss rate is required for the core network.

The recommended packet loss rate over the Iu interface is less than one of a million.

Precautions

Activate this feature when the traffic volume in a cell is low. The reason is that the cell must be

deactivated before this feature is activated; after the cell is deactivated, the services in this cell areinterrupted.

Activation

Step 1 Change the NodeB's and CN's protocol versions to versions that support DC-HSDPA.

NOTE

3GPP Release 8 and later support DC-HSDPA. It is recommended that the NodeB's protocol version be set to Release 9and that the CN's protocol version be set to Release 8.

1. Run the RNC MML command MOD UNODEB to set NodeB Protocol Version to R9.

2. Run the RNC MML command MOD UCNNODE to set CN domain ID to PS_DOMAIN and set CN protocol version

to R8.

Step 2 Run the RNC MML command DEA UCELL multiple times to deactivate each logical cell of thecells to be enabled with DC-HSDPA.

Step 3 Run the NodeB MML command ADD DLDUALCELLGRP to add the cells to a DC-HSDPA cellgroup.

NOTE

Only the cells that meet the requirements described in section 3.2.2 "DC-HSDPA Cell Groups" can be added to aDC-HSDPA cell group.

Step 4 (Optional) Run the RNC MML command MOD UCELLSETUP to modify the value of the Time

Offset parameter based on the prepared data.

NOTE

Step 3 is required only when the value of the Time Offset parameter is inconsistent between DC-HSDPA cells. The valueof the Time Offset parameter can be queried using the LST UCELL command.

Step 5 Run the RNC MML command ACT UCELL multiple times to activate the cells in theDC-HSDPA cell group.

Step 6 Run the RNC MML command SET UCORRMALGOSWITCH to turn on the DC-HSDPAbearing switch by selecting CFG_HSDPA_DC_SWITCH in the Channel Configuration StrategySwitch parameter.















WCDMA RAN




7-5

Step 7 Run the RNC MML command SET UFRC to select DC-HSDPA as the preferential HSPA+technology by selecting DC_HSDPA in the Preferred MIMO_64QAM or DC_HSDPA Characterparameter.

NOTE

Select DC_HSDPA in the Preferred MIMO_64QAM or DC_HSDPA Character parameter before feature verification. Ifthe planned HSPA+ technology for a cell is not DC-HSDPA, select the planned HSPA+ technology as required afterfeature verification.

Step 8 (Optional) If streaming services need to use DC-HSDPA, run the RNC MML command SETUCORRMALGOSWITCH to select MAP_PS_STREAM_ON_HSDPA_SWITCH in the Service MappingStrategy Switch parameter.

Step 9 Run the RNC MML command MOD UCELLALGOSWITCH multiple times to enable DC-HSDPAby selecting DC_HSDPA(Cell DC-HSDPA Function Switch) in the Cell Hspa Plus functionswitch parameter.

Step 10 (Optional) When DC-HSDPA DRD is required, run the RNC MML command SET UFRC to

enable DC-HSDPA DRD by selecting DC_HSDPA in the HSPA Technologies Retried by UEs parameter.

----End

Activation Observation

Monitor counters or trace signaling to check whether DC-HSDPA is working properly.

Monitoring Counters

Monitor the value of the VS.HSDPA.RAB.DC.SuccEstab counter for DC-HSDPA cells. If the value of thiscounter is not zero for a DC-HSDPA cell, DC-HSDPA is working properly for that cell.

Tracing Signaling

Step 1 Click Uu Interface Trace on the LMT, as shown in Figure 7-1.



WCDMA RAN




7-6

Figure 7-1 Uu Interface Trace dialogue box

Step 2 For cells with Cell DC-HSDPA Function Switch turned on, trace RRC_RB_SETUP messageson the Uu interface.

Step 3 Perform dialing tests on FTP services for a UE to ensure that data is transmitted on HSDPAchannels.

Step 4 On the Trace tab page of the LMT, check whether RRC_RB_SETUP messages contain thedl-SecondaryCellInfoFDD information element.

If the dl-SecondaryCellInfoFDD information element is contained, as shown in Figure 7-2, it indicatesthat the feature is activated.

If the dl-SecondaryCellInfoFDD information element is not contained, it indicates that the feature is

not activated.

Deactivation

Step 1 Run the RNC MML command MOD UCELLALGOSWITCH to disable DC-HSDPA in a cell bydeselecting DC_HSDPA(Cell DC-HSDPA Function Switch) in the Cell Hspa Plus function switch parameter.

Step 2 Run the RNC MML command MOD UCELLALGOSWITCH to turn off the DC-HSDPA bearingswitch by deselecting CFG_HSDPA_DC_SWITCH in the Channel Configuration Strategy Switchparameter.

Step 3 Run the RNC MML command DEA UCELL to deactivate the logical cells of the localDC-HSDPA cells.

Step 4 Run the NodeB MML command RMV DLDUALCELLGRP to remove the DC-HSDPA cellgroup.

Step 5 Run the RNC MML command ACT UCELL to activate the cells that are deactivated in Step 3.

7.1.5 Performance Monitoring

Monitoring Counters

To determine the number of DC-HSDPA radio access bearers (RABs) or DC-HSDPA users in a cell,check the values of the following RNC counters:

VS.HSDPA.RAB.DC.AttEstab: number of attempts to set up DC-HSDPA RABs on the primary carrierin the DC-HSDPA cell

VS.HSDPA.RAB.DC.SuccEstab: number of successful DC-HSDPA RAB setups on the primary carrierin the DC-HSDPA cell

VS.HSDPA.DC.PRIM.UE.Mean.Cell: average number of users that have chosen the current cell asthe primary cell

VS.HSDPA.DC.SEC.UE.Mean.Cell: average number of users that have chosen the current cell as thesecondary cell

To obtain the information about the scheduling of DC-HSDPA users under a NodeB, check the values ofthe following NodeB counters:

VS.HSDPA.DCCfg.AnchorCarrierActedNum: number of times during a measurement period that thecurrent cell has performed scheduling for users that are configured with DC-HSDPA and have chosenthe current cell as the primary cell, regardless of whether the secondary carrier has performedscheduling simultaneously. If the primary and secondary carriers have performed scheduling for auser simultaneously, only one time is counted.

VS.HSDPA.DCCfg.SupCarrierActedNum: number of times during a measurement period that thecurrent cell has performed scheduling for users that are configured with DC-HSDPA and have chosen

the current cell as the secondary cell, regardless of whether the primary carrier has performedscheduling at the same time. If the primary and secondary carriers have performed scheduling for auser simultaneously, only one time is counted.

VS.HSDPA.DCCfg.DualCarrierActedNum: number of times during a measurement period thatscheduling has been performed by the primary and secondary carriers at the same time for users thatare configured with DC-HSDPA and have chosen the current cell as the primary cell.

DC-HSDPA increases the cell throughput and peak rates for individual users. To determine the averageDC-HSDPA UE throughput, average cell HSDPA throughput, and total downlink throughput before andafter DC-HSDPA is deployed, check the values of the following counters:

VS.CellReserve.Counter3: This counter measures the amount of traffic that is correctly transmitted forDC-HSDPA/DC-HSDPA+MIMO UEs at the MAC-ehs layer. This counter is in units of kbit/s.

VS.CellReserve.Counter4: This counter measures the number of TTIs during whichDC-HSDPA/DC-HSDPA+MIMO buffer queues have data to transmit. If multiple queues have data totransmit in a TTI, the TTI number needs to be multiplied by the number of queues that have data totransmit. This counter is measured only on the primary carrier.

Use the following formula to calculate the average DC-HSDPA UE throughput at the base stationlevel:

VS.HSDPA.MeanChThroughput: an RNC counter that measures the average downlink throughput ofindividual MAC-d flows for HSDPA in the cell.



WCDMA RAN




7-9

The value of this counter is an average. The peak data rate per user can only be checked in drivetests.

VS.DataOutput.Mean: a NodeB counter that measures the average throughput at theMAC-hs/MAC-ehs layer in the cell during a measurement period.

Monitoring KPIs

The following cell-level KPIs indicate the performance of DC-HSDPA:

DC-HSDPA RAB Setup Failure Rate = 1 -(VS.HSDPA.RAB.DC.SuccEstab/VS.HSDPA.RAB.DC.AttEstab) x 100%

After DC-HSDPA is enabled, this KPI measures the DC-HSDPA RAB setup failure rate. If theDC-HSDPA RAB setup failure rate is much greater than the SC-HSDPA RAB setup failure rate, theproportion of UEs supporting DC-HSDPA may be very low or the DC-HSDPA traffic volume may bevery small. Under either condition, the value of the VS.HSDPA.RAB.DC.AttEstab counter is small.

When the proportion of UEs supporting DC-HSDPA is very low or the DC-HSDPA traffic volume isvery small, this KPI cannot indicate the actual DC-HSDPA RAB setup failure rate.

DC-HSDPA Call Drop Rate = VS.HSDPA.RAB.AbnormRel.DC/(VS.HSDPA.RAB.AbnormRel.DC+VS.HSDPA.RAB.NormRel.DC) x 100%

After DC-HSDPA is enabled, this KPI measures the DC-HSDPA call drop rate. If the DC-HSDPA calldrop rate is much greater than the SC-HSDPA call drop rate, the proportion of UEs supportingDC-HSDPA may be very low or the DC-HSDPA traffic volume may be very small. Under eithercondition, the value of the VS.HSDPA.RAB.DC.AttEstab counter is small.

When the proportion of UEs supporting DC-HSDPA is very low or the DC-HSDPA traffic volume isvery small, this KPI cannot indicate the actual DC-HSDPA call drop rate.

7.2.1 When to Use Traffic-Based Activation and Deactivation of theSupplementary Carrier In Multi-carrier

This feature applies to all scenarios. This feature brings about the following benefits:

Reduced uplink load on the RAN side



WCDMA RAN




7-10

Reduced UE power consumption in theory, depending on UE specifications.

This feature increases transmission delay of burst services for DC-HSDPA users, affecting userexperience. Therefore, you are advised to enable this feature on heavily loaded networks. For lightlyloaded networks, the operator can decide whether to use this feature as follows:

Disable this feature if the transmission delay of burst services needs to be reduced.

Enable this feature if UE power needs to be saved.

7.2.2 Information to Be Collected

Collect the following information before deploying this feature:

MC UE penetration rate

MC UEs include DC-HSDPA UEs and DC-HSDPA+MIMO UEs.

The larger the ratio of VS.HSDPA.DC.PRIM.UE.Mean.Cell to VS.HSDPA.UE.Mean.Cell, the moregains this feature brings.

Mean UE throughput

The smaller the value is for VS.HSDPA.MeanChThroughput, the more gains this feature brings.

7.2.3 Feature Deployment

This section describes how to activate, verify, and deactivate the optional feature WRFD-010713Traffic-Based Activation and Deactivation of the Supplementary Carrier In Multi-carrier.

Prerequisites

Dependencies on Hardware

This feature does not have any special requirements for hardware.

Dependencies on Other Features

WRFD-010696 DC-HSDPA

License

The license "the number of cells with traffic-based activation and deactivation of the slave carrierfunction enabled" on the NodeB side has been activated. For details about the license items and howto activate the license, see License Management Feature Parameter Description.

Other Prerequisites

The UE must be of HS-DSCH category 21, 22, 23, 24 to support DC-HSDPA or HS-DSCH category 25,26, 27, 28 to support DC-HSDPA+MIMO.

Activation ProcedureRun the NodeB MML command SET MACHSPARA (CME single configuration: NodeB ConfigurationExpress > IUB_NodeB > Radio Layer > Locell Algorithm Parameters > MAC Parameters >MACHSPARA; CME batch modification center: Modifying Physical NodeB Parameters in Batches) to setthe Mac-hs scheduling parameters with the DC HSDPA Cell Act Deact Switch set to ON(ON).

If the Mac-hs scheduling parameters of two DC-HSDPA cells must be set, set DC HSDPA Cell Act Deact Switch toON(ON) for each cell.

Verification Procedure

1. Run the NodeB MML command LST MACHSPARA to query the Mac-hs scheduling parameters.

Check whether the Secondary DC HSDPA Cell Act Deact Switch is turned on.

WCDMA RAN




7-11

2. Run the BSC6900 MML command SET UCORRMALGOSWITCH. In this step, clearDRA_HSDPA_STATE_TRANS_SWITCH , DRA_HSUPA_STATE_TRANS_SWITCH , andDRA_PS_BE_STATE_TRANS_SWITCH from the Dynamic Resource Allocation Switch list.

3. Use a DC-HSDPA UE to perform PS services in a DC-HSDPA cell. Do not upload or download data

after required connections are established. Five seconds later, the UE becomes an SC UE, whichindicates that the feature has been activated.

Deactivation Procedure

Run the NodeB MML command SET MACHSPARA (CME single configuration: NodeB ConfigurationExpress > IUB_NodeB > Radio Layer > Locell Algorithm Parameters > MAC Parameters >MACHSPARA; CME batch modification center: Modifying Physical NodeB Parameters in Batches) to setthe Mac-hs scheduling parameters with the Secondary DC HSDPA Cell Act Deact Switch set toOFF(OFF).

Example

//Activation procedure

SET MACHSPARA: LOCELL=1, SECCELLACTDEASW=ON;

SET MACHSPARA: LOCELL=2, SECCELLACTDEASW=ON;

//Deactivation procedure

SET MACHSPARA: LOCELL=1, SECCELLACTDEASW=OFF;

SET MACHSPARA: LOCELL=2, SECCELLACTDEASW=OFF;

7.2.4 Feature Monitoring

The ratio of the throughput-based secondary cell active time over the user-existence time ofDC-HSDPA&DC-HSDPA+MIMO users can be monitored by the NodeB counterVS.HSDPA.DCCfg.SupCarrierDeact.TimeRatio .

For a single DC-HSDPA user, this function reduces the uplink load only by a limited degree. If there are alarge number of DC-HSDPA users, this function reduces the uplink load significantly. Follow these stepsto calculate the uplink load gain for a cell:

1. With this function disabled, obtain the value of VS.MinRTWP when the cell is idle and the value ofVS.MeanRTWP when some DC-HSDPA users are camping on the cell. Then, calculate thedifference between the values of VS.MinRTWP and VS.MeanRTWP and record it as RTWPoff .

2. With this function enabled, obtain the value of VS.MinRTWP when the cell is idle and the value ofVS.MeanRTWP when some DC-HSDPA users are camping on the cell. Then, calculate thedifference between the values of VS.MinRTWP and VS.MeanRTWP and record it as RTWPon.

3. Calculate the difference between the values of RTWPoff and RTWPon to obtain the uplink load gainyielded by this function.

The uplink load gain is easily affected by the number of DC-HSDPA users, the channel condition, andother users, and its absolute value is small. As a result, it is not easy to notice a stable uplink load gain.
