( https://gerrit.osmocom.org/c/osmo-bts/+/25474 ) Change subject: scheduler: Apply BCCH Carrier Power Reduction attenuation to PDCH TS on C0 ...................................................................... scheduler: Apply BCCH Carrier Power Reduction attenuation to PDCH TS on C0 The commit implementing BCCH Carrier Power Reduction forgot to apply it for bursts for which there's no lchan controlled by OsmoBTS, such as those coming from PDCH timeslots. For other TRX, BS Power Reduction is still always 0. The BS Power Control Loop for those channels still needs to be implemented in OsmoPCU and the resulting bs_powerbe passed somehow over PCUIF together with RLCMAC data to OsmoBTS, so it can be applied there.
