8 Engineering Guidelines
1. Run the BSC6900 MML command MOD UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell HSDPA Parameters; CME batch modification
center: Modifying UMTS Cell Parameters in Batches) to set Code Number for HS-SCCH to 1.
The BSC6900 MML command MOD UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express >
Cell Parameters > Cell HSDPA Parameters; CME batch modification center: Modifying UMTS Cell Parameters in Batches) fails to be executed when HSDPA is activated. Therefore, run the BSC6900 MML command DEA
UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell HSDPA Parameters. Set ACTSTATUS to Deactivated; CME batch configuration: No supported) to deactivate HSDPA before
configuring this feature and run the BSC6900 MML command ACT UCELLHSDPA (CME single configuration: UMTS Cell
Configuration Express > Cell Parameters > Cell HSDPA Parameters. Set ACTSTATUS to Activated; CME batch
configuration: No supported) to reactivate HSDPA after configuring this feature.
The BSC6900 MML command MOD UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express >
Cell Parameters > Cell HSDPA Parameters; CME batch modification center: Modifying UMTS Cell Parameters in Batches) fails to be executed when CELL-FACH enhancement is activated. Therefore, run the BSC6900 MML command
DEA UCELLEFACH (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell Enhanced FACH parameters. Set Validation indication to Deactivated; CME batch configuration: No supported) to
deactivate enhanced CELL-FACH before configuring this feature and Run the BSC6900 MML command ACT
UCELLEFACH (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell Enhanced FACH parameters. Set Validation indication to Activated; CME batch configuration: No supported) to reactivate
enhanced CELL-FACH after configuring this feature.
By default, the number of HS-SCCH codes for each cell is 4. If the default number is used, the HS-PDSCH can use only 14 SF16 codes. To enable the HS-PDSCH to use all 15 SF16 codes, run the BSC6900 MML command MOD
UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell HSDPA Parameters; CME batch modification center: Modifying UMTS Cell Parameters in Batches) to set the value of Code
Number for HS-SCCH to 1.
2. Run the BSC6900 MML command MOD UCELLHSDPA (CME single configuration: UMTS Cell Configuration Express > Cell Parameters > Cell HSDPA Parameters; CME batch modification center: Modifying UMTS Cell Parameters in Batches) to set Allocate Code Mode to Manual(Manual) and Code Number for HS-PDSCH to 15.
Verification Procedure
1. Initialize UMTS monitoring on the BSC6900 LMT, as shown in Figure 6-1. Click Submit. A real-time monitoring window is displayed.

2. Check whether 15 SF16 codes are occupied by the HS-PDSCH in the Cell Performance Monitoring window.
Expected result: The HS-PDSCH occupies 15 SF16 codes.
Deactivation Procedure
This feature does not need to be deactivated.
