Abstract: Methods and apparatuses are provided in which first downlink control information (DCI) for scheduling a physical downlink shard channel (PDSCH) is transmitted to a terminal. Second information indicating one among preset first values is included in the DCI. The PDSCH associated with the DCI is transmitted to the terminal. Acknowledgement information associated with the PDSCH is received from the terminal based on a first transmission time interval (TTI) determined based on both a TTI associated with the PDSCH and a value associated with the second information. The preset first values are numbers of at least one TTI between the TTI associated with the PDSCH and a TTI for transmission of the acknowledgement information associated with the PDSCH.
