Abstract: A method, performed by a terminal in a wireless communication system, of transmitting and receiving data information is provided. The method includes receiving multiple transmission unit scheduling information, receiving information about whether demodulation reference signal (DMRS) time bundling is feasible with respect to DMRS information respectively contained in a plurality of transmission units scheduled according to the multiple transmission unit scheduling information, and when the information indicates that the DMRS time bundling is feasible, performing decoding on data information based on at least one of a hybrid automatic request (HARQ) acknowledge (ACK)/negative acknowledge (NACK) transmission time, a size of a frequency resource of a downlink (DL) physical data channel to which the data information scheduled according to the multiple transmission unit scheduling information is assigned, a timing advance value, and a time required for a valid data process.
