Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information related to a concurrent reception capability using different receive beams. The UE may receive, from the base station, information indicating one or more slots in which concurrent sidelink and downlink reception is enabled based at least in part on the information related to the concurrent reception capability. The UE may receive, in the one or more slots in which concurrent sidelink and downlink reception is enabled, a downlink transmission from the base station using a first receive beam and a sidelink transmission from a peer UE using a second receive beam. Numerous other aspects are described.
