1. A processor of a first base station configured to perform operations comprising:
establishing a first backhaul communication link with a second base station, the second base station having one of a second backhaul communication link with a third base station or an access link with a user equipment (UE);
generating, for transmission to the second base station, a medium access control (MAC) control element (CE) indicating first beam management parameters for the second base station to use for receiving a downlink (DL) transmission from the first base station on the first backhaul link and first DL transmission parameters for the DL transmission, wherein the first beam management parameters include beam and panel parameters for receiving the DL transmission from the first base station;
receiving second beam management parameters from the second base station which modify the first beam management parameters and second DL transmission parameters which modify the first DL transmission parameters;
determining whether to use the second beam management parameters and the second DL transmission parameters; and
when the second beam management parameters and the second DL transmission parameters are determined to be used, scheduling, for the second base station, the DL transmission in accordance with the second beam management parameters and the second DL transmission parameters so that the DL transmission will be received at the second base station simultaneously with a UL transmission from at least one of the third base station and the UE, wherein the UL transmission is scheduled by the second base station using UL transmission parameters configured in dependence on the second DL transmission parameters.
