1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, control information for scheduling downlink transmission using at least one transmission reception point (TRP);
identifying that at least a part of a signal, transmitted by a first TRP of the at least one TRP, is to be retransmitted by a second TRP of the at least one TRP, based on the control information;
identifying a code division multiplexing (CDM) group of the second TRP for receiving the at least the part of the signal based on the control information;
receiving, from the second TRP, the at least the part of the signal based on the CDM group of the second TRP; and
combining the signal received from the first TRP and the at least the part of the signal received from the second TRP.
