Main characteristics of HS-TX boards

The capacity of a HS-TX board is called Resource_Id.

1 Resource_Id can be configured for:

- 128 CEs for DCH R99 including CCH, CM and SoHO- 30 HS-PDSCH codes shared between up to 6 cell-carriers- E-UL including the DL channels and the Scheduler

If the HSDPA is activated, the EUL service can be also activated, but it depends of the hardware capacity.

One Resource_id can support a maximum of 96 E-UL users. Each Resource_id with HSDPA supports up to 128 HSDPA users, divided between

one to six cells. It is possible to serve up to 128 HSDPA users in all cells configured for one Resource_id and a maximum of 96 users in a single cell.

Manipulating the resourcesThe RBS reserves some resources to A-DCH. It depends of the number of HS

users per cell is activated in the license key.

The RBS 6000 is more efficient than RBS 3000 of reserving A-DCH CEs.

For example: 4 HS users/cell 3 cell-site:

4 users x 3 cells x 1,3* x 0,5 = 7,8 ~ 8 CEs -> reserved to A-DCH

* 1,3 is the recommended factor to guarantee enough resources during soft handover events.

Then, from all channel elements available to DCH (R99 traffic) it is necessary to discount 8 channels elements those are reserved to A-DCH.

(DUW 20) numHsCodeResources = 2 / numEulResources = 1For this case its necessary to consider 2 HS resources because there are more

than 128 HS users.
