Automatic IRC Tuning is used instead of Automatic FLP by operators
that wants to maximize IRC (and SAIC) performance but do not use FLP. As with
Automatic FLP, the feature performs daily downlink interference matrix measurements
and creates synchronization clusters for synchronization status monitoring. TSC
and FSOFFSET parameters are continuously supervised and automatically adjusted
to network changes when needed.
By using
Automatic IRC Tuning an operator will get the following benefits:
>Automatic configuration of IRC (Interference Rejection
Combining) related parameters:
- TSC for hopping channel groups.
- FSOFFSET for neighbor cells that are
GPS synchronized. By this co-TSC interference can be suppressed.
> Maximum gain from IRC and SAIC.
> Possibility to monitor synchronization status for Synchronized
Radio Network cells.
Automatic IRC Tuning is allowed to be activated in the same BSC as
Automatic FLP. When both features are active in the same cell it will behave as
Automatic FLP.
