Patent ID: 11564254

Abstract:
Methods, systems, and devices for wireless communications are described. A base station may determine a transmission beam configuration for transmitting multicast data to a user equipment (UE) in a joint transmission using a set of transmission/reception points (TRPs) based on outcomes of listen before talk (LBT) procedures performed at the TRPs. In some examples, the base station may indicate to the UE that the UE is to determine a UE beam configuration and a quasi co-location (QCL) relationship associated with the TRPs for receiving the multicast data based on signaling from the TRPs. In some examples, the base station may transmit multicast data from a first TRP (e.g., a serving cell) during a first transmission opportunity (TxOP), and the UE may determine the QCL relationship for the set of TRPs. During a second TxOP, the base station may transmit multicast data in a joint transmission from the set of TRPs.
