The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting higher data transfer rates. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving configuration information on a resource for transmitting a first physical uplink shared channel (PUSCH) based on a configured grant, the first PUSCH being associated with a first control resource set (CORESET) pool identifier; receiving downlink control information (DCI) including information on a resource for transmitting a second PUSCH based on a dynamic grant (DG), the second PUSCH being associated with a second CORESET pool identifier, wherein the resource for transmitting the first PUSCH overlaps with all or part of the resource for transmitting the second PUSCH in a time domain; identifying whether a value of the first CORESET pool identifier is different from a value of the second CORESET pool identifier; and in case that the value of the first CORESET pool identifier is identified to be different from the value of the second CORESET pool identifier, transmitting the first PUSCH and the second PUSCH.
