Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided is a method performed by a user equipment (UE), the method including receiving downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs); identifying a value of a hybrid automatic repeat and request (HARQ) feedback timing indicator included in the received DCI; and performing the HARQ feedback transmission, based on the identified value of the HARQ feedback timing indicator, wherein in case that the value is identified as a non-numerical value, HARQ feedback information for the plurality of PDSCHs is not transmitted based on the DCI and the HARQ feedback information for the plurality of PDSCHs is transmitted after an other DCI including a numerical value of the HARQ feedback timing indicator is received.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In a method performed by a UE in the communication system, the UE receives, from a base station, an RRC message including PDSCH resource allocation information and TCI information; receives, from the base station, DCI for scheduling at least one PDSCH through a first PDCCH; and receives, from the base station, data through the at least one PDSCH. In case that TCI information related to the at least one PDSCH is different from TCI information related to a second PDCCH overlapping the at least one PDSCH in a time domain and a beam switching time is required between the at least one PDSCH and the second PDCCH, the UE does not expect the second PDCCH to be searched in a region overlapping with the at least one PDSCH.
