1. A method performed by a terminal in a communication system, the method comprising:
transmitting a physical uplink shared channel (PUSCH) to a base station;
receiving, from the base station, a physical downlink control channel (PDCCH) including a hybrid automatic repeat request (HARQ)-acknowledgment (ACK) information; and
identifying whether the HARQ-ACK information is valid for the PUSCH based on a time interval between a PDCCH reception and a PUSCH transmission,
wherein the HARQ-ACK information is identified to be valid for the PUSCH in case that the PDCCH reception is after minimum duration from the PUSCH transmission.
