The UE may estimate, for each of the one or more candidate beams in the set of candidate beams, a downlink spectral efficiency and an uplink spectral efficiency based at least in part on the RSRP measurements associated with the respective candidate beam. The UE may select a downlink receive beam and an uplink transmit beam based at least in part on the downlink spectral efficiency and the uplink spectral efficiency. Numerous other aspects are described.

A node may forward, from a base station to a first UE, or from the first UE to the base station, one or more wireless signals. The node may identify an indication to stop signal forwarding to the first UE. The indication may be based on a level of an interference to a second UE associated with the signal forwarding to the first UE being greater than a first threshold. The level of the interference to the second UE may be based on a path gain difference or a signal strength at the first UE associated with the signal forwarding to the first UE. The signal strength at the first UE associated with the signal forwarding to the first UE may correspond to an RSRP at the first UE. The node may stop the signal forwarding to the first UE based on the indication.
