fixeria gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bsc/+/24739 to look at the new patch set (#2). Change subject: power_control: implement BCCH carrier power reduction operation ...................................................................... power_control: implement BCCH carrier power reduction operation The BCCH carrier (sometimes called C0) of a BTS shall maintain discontinuous Downlink transmission at full power in order to stay 'visible' to the mobile stations. Because of that, early versions of 3GPP TS 45.008 prohibited BS power reduction on C0. However, in the recent 3GPP TS 45.008 there is a feature called 'BCCH carrier power reduction operation'. This is a special mode of operation, where the variation of RF level for some timeslots is relaxed for the purpose of energy saving. In BCCH carrier power reduction operation, for timeslots on the C0 carrier, except timeslots carrying BCCH/CCCH, the output power may be lower than the output power used for timeslots carrying BCCH/CCCH. In this case the maximum allowed difference in output power actually transmitted by the BTS is 6 dB. Introduce a new 'bs-power-c0' configuration command, complementing the existing 'bs-power' command, in order to allow constrained BS power reduction on *active channels* of the BCCH carriers. In lchan_fsm_wait_ts_ready_onenter(), distinguish between the BCCH and non-BCCH carriers, apply the appropriate default value.
