Configuring Anti-Interference Scheduling for

HSUPA

This section describes how to activate, verify, and deactivate the optional feature WRFD-020136 Anti-

Interference Scheduling for HSUPA.

Prerequisites

Dependencies on Hardwareo The BTS3812E/BTS3812AE must be configured with the HBBI/HULP/EBBI/EBOI/EULP or

EULPd board. Downlink services can be established only on the EBBI/EBOI or EDLP board.

o The BBU3806 must be configured with the EBBC or EBBCd board; the BBU3806C must be

configured with the EBBM board.o The BBU3900 is configured with the WBBPb or WBBPd board.

Dependencies on Other Features

o WRFD-010612 HSUPA Introduction Package

Licenseo The license controlling this feature has been activated.

Context

In commercial networks, the uplink data transmission of HSUPA at some sites is affected randomly by strongexternal interference. When a site is strongly interfered, the HSUPA throughput of the site is significantlyreduced and user experience is affected.

This feature can eliminate the strong external interference and maintain high HSUPA throughput, improvinguser experience.

NOTE:This feature is not proposed for multi-RRU cells.

Procedure

Activation Procedure1. Run the NodeB MML command SET MACEPARA to set Mac-e parameters.

a. Set the MAC-e Schedule Para to YES(YES).

b. Set the Anti-Interference Scheduling Switch to ON(ON).

c. Own Cell UL Load Ratio In indoor coverage scenarios, the recommended value is 90.

In non-indoor coverage scenarios, the recommended value is 60.

d. It is recommended to set the Min UL Cover Load Threshold(dB) to 13.

NOTE:

If Local Cell ID is not specified, the Mac-e scheduling parameters of all local cells under the

NodeB will be set.

2. Run the BSC6900 MML command MOD UCELLHSUPA, it is recommended to set the

Maximum Target Uplink Load Factor to 75.

Verification Procedure

1. Run the NodeB MML command DSP LICENSE to display license information.

Exception result: the value of Anti-Interference Scheduling for HSUPA Function(per Cell) is

bigger than 0.

2. Run the NodeB MML command SET MACEPARA to set Mac-e parameters.

Set the MAC-e Schedule Para to YES(YES).

Set the Anti-Interference Scheduling Switch to OFF(OFF).

3. Make interference.

For example: Run the NodeB MML command SET DESENS, set Desensitization Intensity to

6.

4. Use a UE to carry out HSUPA upload task.

5. Select Service > Realtime Specific Monitoring > Cell RTWP from the navigation tree in

Maintenance tab on NodeB LMT, as shown in Figure 1. The column 1-3 indicates the state ofthis feature disabled.

Figure 1 Cell RTWP (feature disabled)

6. Run the NodeB MML command SET MACEPARA to set Mac-e parameters.

. Set the Anti-Interference Scheduling Switch to ON(ON).

a. Own Cell UL Load Ratio In indoor coverage scenarios, the recommended value is 90. In non-indoor coverage scenarios, the recommended value is 60.

b. It is recommended to set the Min UL Cover Load Threshold(dB) to 13.

NOTE:

If Local Cell ID is not specified, the Mac-e scheduling parameters of all local cells under the

NodeB will be set.

7. Select Service > Realtime Specific Monitoring > Cell RTWP from the navigation tree in

Maintenance tab on NodeB LMT, as shown in Figure 1. The column 1-3 indicates the state of

http://localhost:7890/pages/31184925/03/31184925/03/resources/mbsc/m-bsc-reconfiguration-guide/WRFD-020136.html?ft=99&fe=1&id=WRFD-020136&keyword=owncellulloadratio&noteId=#WRFD-020136__fig1










this feature enabled. If the values of column 1-3 in Figure 1 are bigger than the values of 1-3 in

Figure 2, it indicates the feature has been enabled.

Figure 2 Cell RTWP (feature enabled)

Deactivation Procedure1. Run the NodeB MML command SET MACEPARA to set Mac-e parameters.

Set the MAC-e Schedule Para to YES(YES).

Set the Anti-Interference Scheduling Switch to OFF(OFF).
