Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An apparatus and a method performed by the same in a wireless communication system are disclosed. The method includes: receiving configuration information from a base station; and receiving a downlink signal from the base station based on the configuration information, the downlink signal including downlink data. The downlink data includes a unicast physical downlink shared channel (PDSCH) and/or a multicast/broadcast PDSCH, the unicast PDSCH includes a dynamically scheduled unicast PDSCH and/or a unicast semi-persistent scheduling (SPS) PDSCH, and the multicast/broadcast PDSCH includes a dynamically scheduled multicast/broadcast PDSCH and/or a multicast/broadcast SPS PDSCH. The present disclosure improves the efficiency of uplink or downlink transmission.
