Configuring Dual-Threshold Scheduling with

HSUPA Interference Cancellation

This section describes how to activate, verify, and deactivate the optional feature WRFD-020137Dual-Threshold Scheduling with HSUPA Interference Cancellation.

Prerequisites

Dependencies on Hardwareo The BTS3812E or BTS3812AE must be configured with the EULPd board.o The DBS3800 must be configured with the EBBCd board.o The 3900 series base stations must be configured with the WBBPd board in slot 2

or slot 3. For detailed installation steps, see theBBU3900 Installation Guide.

Dependencies on Other Featureso

WRFD-010612 HSUPA Introduction Packageo WRFD-010691 HSUPA UL Interference Cancellation

Licenseo The license controlling this feature has been activated.

Context

This feature is applicable in cells enabled with the WRFD-010691 HSUPA UL Interference

Cancellation feature.

Procedure

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

Set the MAC-e Schedule Para to YES. Set the Max Target RoT Difference Before and After IC to 2.

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

Max Target RoT Difference Before and After IC to 0.

2. Use multi users to carry out upload service.3. Select Service > Realtime Specific Monitoring > Cell RTWP from the

navigation tree in Maintenance tab on NodeB LMT, as shown inFigure 1. The

column 1-3 indicates the state of this feature disabled, the column 1-4 indicatesthe state of this feature enabled. If the value of column 1-4 is less than the value

of column 1-3, it indicates HSUPA UL Interference Cancellation feature has beenenabled.

4. Run the NodeB MML command SET MACEPARA to set Mac-e parameters. SetMax Target RoT Difference Before and After IC to 2.

5. Check the Cell RTWP window. If the value of column 1-4 is less than the valueof column 1-3, and the values of column 1-4 and column 1-3 increase by 10, itindicates dual-threshold scheduling with HSUPA interference cancellation feature

has been enabled.

NOTE:

The prerequisite of the foregoing result is the cell power limit does not over.

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

Max Target RoT Difference Before and After IC to 0.

2. Reallocate the license of this feature on M2000 LMT, and set Allocated to 0.Example
