Abstract:
Methods, systems, and devices for wireless communications are described for concurrent communications between multiple transmission-reception points (TRPs) and a user equipment (UE). A default beam for each of the TRPs may be determined, and in the case that the default beams are unable to be concurrently received at the UE, a prioritization rule may be applied to determine which TRP uses the initially determined default beam, where the other TRP(s) may use a different beam. A UE also may be configured with a subset of control resource sets for each TRP, such that beams associated with different configured subsets are compatible and able to be concurrently received at the UE. Other techniques for providing compatibility between beams of multiple concurrent TRP transmissions include determination of a first beam, and selection of a second beam based on a mapping to the first beam, or explicit configuration by a base station.
