100% OK with Klumzy 🙂
MKT, to be clear : yes, the PC is enable at cell level, for DL, UL or both directions.
However, DL PC will NEVER work on the timeslots that are sent on-air onto the BCCH frequency (TS 0…7).
Even if the TCH is not allocated on the BCCH TRX, here are the impacts of bad C/I on the BCCH & SDCCH :
– poor paging success
– poor immediate assignment success
– poor channel request success
– poor SDCCH assignment success
– poor SDCCH drop
– poor TCH assignment success
you will also suffer from MS that cannot decode the SI messages in Idle mode, and which will consequently reselect another cell (even if RXLEV is lower..)
It will also induce problems in GPRS (TBF establishment failure, and re-establishment failure)
For all those reasons, the BCCH C/I should always be better than TCH C/I.
