Patent ID: 10925116

Abstract:
A UE can include processing circuitry coupled to memory. To configure the UE for semi-persistent scheduling (SPS) transmission or a grant-free transmission, the processing circuitry is to decode RRC signaling from a base station, the RRC signaling configuring a plurality of transmission configuration information (TCI) candidates indicating a first set of transmission beams for an initial transmission on an SPS PDSCH. The initial transmission uses an initial transmission beam that is selected based on a TCI beam index. A MAC CE from the base station is decoded, the MAC CE indicating a re-configuration of the plurality of TCI candidates to include at least a second set of transmission beams for the SPS PDSCH. A transmission beam is selected from the second set of transmission beams based on the TCI beam index. Downlink data received in a subsequent transmission via the selected transmission beam on the SPS PDSCH is decoded.
