Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. A method of a terminal in a wireless communication system includes receiving, from a base station, a reference signal to be used for measuring channel information for each of at least one slot, including a demodulation reference signal (DMRS) related to reception of a physical downlink shared channel (PDSCH), measuring channel information including an interference amount for each of the at least one slot, based on the reference signal, obtaining slot-related channel information, based on the measured channel information for each of the at least one slot, and transmitting the obtained slot-related channel information to the base station. In the method the slot-related channel information is used to determine a modulation and coding scheme (MCS) level for each of at least one slot group.
