Abstract: A communication scheme and a system of converging an IoT technology and a 5th generation (5G) communication system for supporting a higher data transfer rate beyond a 4th generation (4G) system are provided. The communication scheme includes intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety-related services), based on a 5G communication technology and an IoT-related technology. A method performed by a terminal in a communication system is provided. The method includes receiving, from a base station, a semi-persistent scheduling (SPS) configuration including an SPS configuration index; identifying at least one physical downlink shared channel (PDSCH) corresponding to the SPS configuration; identifying a PDSCH with a lowest SPS configuration index in case that the at least one PDSCH corresponding to the SPS configuration is overlapped in time in a slot; determining a PDSCH for data transmission based on excluding a PDSCH that is overlapped with the PDSCH with the lowest SPS configuration index from the at least one PDSCH; and receiving, from the base station, data based on the determined PDSCH, wherein the at least one PDSCH is not overlapped with a symbol indicated as an uplink in the slot.
