fixeria gerrit-no-reply at lists.osmocom.orgfixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/21449 ) Change subject: osmo-bts-trx/scheduler: ensure no DL power attenuation on C0 ...................................................................... osmo-bts-trx/scheduler: ensure no DL power attenuation on C0 When [baseband] frequency hopping is in use, Downlink bursts from additional transceivers may end up being transmitted on TRX0/C0. In this case, we must not apply per-lchan attenuation, because the BTS shall maintain constant power level on that TRX.
