Method and apparatus for transmitting and receiving data information in wireless communication system

A terminal for transmitting and receiving data information in a wireless communication system, the terminal comprising:

• a communicator configured to communicate with a base station (BS);
• and
• at least one processor configured to:
• receive multiple transmission unit scheduling information,
• receive 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, perform decoding on data information based on at least one of a hybrid automatic request (HARQ) acknowledge (ACK)) transmission time/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, or a time required for a valid data process.
