BTS Commissioning Parameters HSDPA scheduler

hsdpaThroughputStep (BTSSCW) - HSDPA throughput steps

• Defines the throughput step that is commissioned for the scheduler. The bigger the vaHSDPA throughput is allocated for the scheduler.

•Value „0‟ has special meaning. It means that HSDPA throughput is not allocated at all for that partiif value „0‟ is commissioned for both schedulers in SM it means that HSDPA is not allocated at all fo(Rel99 only). So if end users want to use whole BTS capacity only for R99 traffic value „0‟ shall be cthe schedulers

•Value „1‟ means 7.2 Mbps throughput, Value „2‟ means 14.4 Mbps throughput and so on. So everyHSDPA throughput step corresponds to 7.2 Mbps actual throughput. Maximum throughput that canone scheduler (35 HSDPA throughput steps) is 35 x 7.2 Mbps = 252 Mbps

Local Cell grouping is needed for Large BTS configurations

• In RU30 single LCG covers up to 12 cells with pure Release 2 HW configuration (S

RF module). Up to four LCGs can be created in pure Rel. 2 HW configuration

• However when 4 Way Rx diversity is used, up to 6 cells with 4 way RX diversity ca

one LCG

• In case of at least one HW Rel.1 (System Module or RF module) or if more than tw

are configured using Antenna 1 and Antenna 3 (type B configuration) for cell from s

dual radio module, up to two LCGs can be created each containing max 6 cells


Local Cell Grouping – Interference Cancellation

• When Interference Cancellation feature is used (System

Module Rel.2 required) only one LCG can be created with

one System Module Rel.2

• When Interference Cancellation feature is used up to two

LCGs can be created with two System Modules Rel.2. In this

case baseband capacity is shared between LCGs according

to the System Module capacity (LCG1: Master System

Local Cell Group can be defined in two different ways

• Sector based (new way) (RU30 EP2)

With sector based pooling, BTS does not check if all the cells from the same frequency lthe same LCG
