1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first information indicating at least one demodulation reference signal (DMRS) type, via a radio resource control (RRC) signaling;
receiving, from the base station, second information indicating whether to activate an enhanced DMRS type corresponding to the at least one DMRS type, via a medium access control-control element (MAC-CE) signaling; and
in case that the second information indicates activation of the enhanced DMRS type, receiving, from the base station, a physical downlink shared channel (PDSCH) or transmitting, to the base station, a physical uplink shared channel (PUSCH) based on the enhanced DMRS type.
