Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) is provided. The method includes receiving, from a base station, a message including configuration information of a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback mode for a multicast semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) without physical downlink control channel (PDCCH) scheduling, receiving, from the base station, downlink control information (DCI) for activation of the multicast SPS PDSCH without PDCCH scheduling, receiving, from the base station, the multicast SPS PDSCH without PDCCH scheduling based on the activation of the multicast SPS PDSCH without PDCCH scheduling, and transmitting, to the base station, HARQ-ACK information for reception of the multicast SPS PDSCH without PDCCH based on the HARQ-ACK feedback mode for the multicast SPS PDSCH without PDCCH scheduling.
