1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message;
determining whether the RRC message includes information associated with frequency domain orthogonal cover codes (FD-OCC); and
receiving, from the base station, downlink control information for scheduling a first physical downlink shared channel (PDSCH) to the terminal based on a first set of orthogonal antenna ports,
wherein, in case that the information is included in the RRC message, a second set of orthogonal antenna ports having a different FD-OCC from a FD-OCC configured for the first set of orthogonal antenna ports are not associated with a transmission of a second PDSCH of another terminal.
