Method for transmitting and receiving data channel based on a plurality of physical uplink shared channels in communication system and apparatus for the same

An operation method of a terminal in a communication system, the operation method comprising:

• receiving, from a base station, downlink control information (DCI) indicating time domain resource allocation information including a start and length indicator value (SLIV) set including N SLIVs, each of the N SLIVs corresponding to each of N physical uplink shared channel (PUSCH) resource regions, and the N being a natural number of 2 or more;
• identifying, in a first slot, a first PUSCH resource region among the N PUSCH resource regions based on a first SLIV among the N SLIVs;
• identifying, in a second slot which is determined based on a location of the first PUSCH resource region, a second PUSCH resource region among the N PUSCH resource regions based on a second SLIV among the N SLIVs;
• transmitting, to the base station, first data in the first PUSCH resource region among the N PUSCH resource regions;
• and
• transmitting, to the base station, second data in the second PUSCH resource region among the N PUSCH resource regions.
