Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a 5G or pre-5G communication system provided to support a higher data transmission rate than a 4G communication system such as LTE. A PDSCH scheduling method in a wireless communication system includes interpreting scheduling information with reference to information associated with an uplink subband, when a UE receives a PDSCH from a base station, by interpreting the size of a scheduled PRB and a bandwidth part size which are appropriate for full-duplex communication. A method of determining a PRG grid and a PRB bundling size which are appropriate for full-duplex communication when a UE receives a PDSCH from a base station includes receiving, from a BS, subband frequency information related to 95frequency domain resource allocation for an UL subband, receiving, from the BS, DC related to frequency domain resource allocation for a PDSCH, identifying a PRG including at least one PRB for the PDSCH based on the subband frequency information and the DCI, and receiving, from the BS, the PDSCH based on the PRG.
