## Abstract

The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a terminal is provided. The method includes receiving, from a base station, a radio resource control (RRC) message including first configuration information for a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback mode related to a multicast physical downlink shared channel (PDSCH) and second configuration information for a physical uplink control channel (PUCCH) resource set related to the HARQ-ACK feedback mode, receiving, from the base station, the multicast PDSCH, and transmitting, to the base station, HARQ-ACK information for the multicast PDSCH based on the first configuration information and the second configuration information.
