Configuring DC-HSUPAThis section describes how to activate, verify, and deactivate the optional feature WRFD-140204 DC-HSUPA.
Prerequisites

Dependencies on Hardware

This feature has the following impact on the NodeB hardware:

All 3900 series base stations support this feature. The WBBPd or WBBPf board must be configured on these base stations.
All DBS3800 series base stations support this feature. The EBBCd board must be configured on these base stations.
The BTS3812E, BTS3812A and BTS3812AE configured with the EBBI, EBOI, EULP, or EULPd board support this feature. Downlink services must be established on the EBBI, EBOI or EDLP board.
When 4-way receive diversity is used, only 3900 series base stations (except the BTS3902E) support this feature.
The uplink peak rate of 23 Mbit/s is applicable only to IP transmission scenarios. The NodeB connects to the transmission equipment through the Ethernet port on the transmission board. In addition to the DPUb or DPUe board, the GOUa, FG2a, POUc, FG2c, or GOUc board must be configured on the RNC.



Dependencies on Other Features

The following features have been configured before this feature is activated:

WRFD-010614 HSUPA Phase 2
WRFD-010695 UL Layer 2 Improvement
WRFD-010652 SRB over HSDPA
WRFD-010636 SRB over HSUPA
WRFD-010696 DC-HSDPA
WRFD-010638 Dynamic CE Resource Management



License

The license controlling this feature has been activated. For details on how to activate the license, see Activating the UMTS License (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/m-bsc-feature-activation-guide/mbsc-11-4.html). For details about license items, see Feature Activation and License Item Descriptions (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/m-bsc-feature-activation-guide/overview-uo.html).
To support a peak rate of 11.5 Mbit/s of a single UE, the license for the feature WRFD-010698 HSPA+ Uplink 11.5 Mbit/s per User must be activated.
To support a peak rate of 23 Mbit/s of a single UE, the license for the feature WRFD-140203 HSPA+ Uplink 23 Mbit/s per User must be activated.


Other Prerequisites

Two DC-HSUPA cells must be on intra-band adjacent carriers that provide the same coverage.
Two adjacent carriers are available and DC-HSDPA has been configured in the downlink.
To support a peak rate of 23 Mbit/s of a single UE, the IP over Iub transmission is used and the uplink bandwidth is greater than 25 Mbit/s.
On the NodeB side, run the SET ETHPORT or ADD ETHPORT command to set Maximum Transmission Unit to 1500. The default value of this parameter is 1500.
The UE must comply with 3GPP Release 9 or later.
The UE must be of HSUPA UE category 8 or 9.
Category-8 UEs support only DC-HSUPA+QPSK. Their peak rate is 11.5 Mbit/s.
Category-9 UEs support DC-HSUPA+16QAM. Their peak rate is 23 Mbit/s.




ContextBefore DC-HSUPA is configured, DC-HSDPA must be configured in cells. For details, see Configuring DC-HSDPA (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/cme-feature-activation-guide/WRFD-010696.html).

Verification Procedure

In the Navigation Tree pane on the RNC LMT, click the Trace tab. In the displayed Trace Navigation Tree pane, double-click UMTS Services. On the unfolded list, double-click Uu Interface Trace. In the displayed Uu Interface Trace dialog box, select RRC_RB_SETUP to trace Uu interface signaling messages of DC-HSUPA cells, as shown in Figure 1 (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/cme-feature-activation-guide/WRFD-140204.html?ft=99&fe=1&id=WRFD-140204&keyword=hspaplusswitch&noteId=#WRFD-140204__fig1).Figure 1 Uu Interface Trace dialog box
http://localhost:7890/pages/31185613/08/31185613/08/resources/image/mbsc/6-reconfiguration-guide/dc-hsupa-1.PNG

Perform dialing tests on FTP services for a DC-HSUPA UE and ensure that HSUPA services have been set up.
On the Trace tab page of the BSC6900 LMT, check whether the RRC_RB_SETUP messages contain the ul-SecondaryCellInfoFDD information element (IE). If the IE is contained, the DC-HSUPA feature has been activated, as shown in Figure 2 (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/cme-feature-activation-guide/WRFD-140204.html?ft=99&fe=1&id=WRFD-140204&keyword=hspaplusswitch&noteId=#WRFD-140204__fig2).Figure 2 Message Explanation

In this step, clear CFG_HSUPA_DC_SWITCH under Channel Configuration Strategy Switch.
To disable the DC-HSUPA feature of a specified cell, Run the BSC6900 MML command MOD UCELLALGOSWITCH (http://localhost:7890/pages/31185613/08/31185613/08/resources/mbsc/m-mml/mod-ucellalgoswitch.html) (CME single configuration:UMTS Cell Configuration Express > Cell Parameters > Cell Algorithm Switches (http://localhost:7890/pages/31185613/08/31185613/08/resources/omc/cme/express/u_cell_exp.html); CME batch modification center: Modifying UMTS Cell Parameters in Batches (http://localhost:7890/pages/31185613/08/31185613/08/resources/omc/cme/express/ucell-batch.html)).
