( https://gerrit.osmocom.org/c/osmo-pcu/+/25504 ) Change subject: scheduler: Skip Tx DL idle blocks in TRX0 when not in DIRECT_PHY mode ...................................................................... scheduler: Skip Tx DL idle blocks in TRX0 when not in DIRECT_PHY mode We also want to avoid sending idle blocs in TRX0 to the BTS, so that the BTS can be aware of blocks being idle and then submitting dummy blokcs by itself applying required BCCH Carrier power reduction.
