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 including first configuration information on a number of reference signal resources associated with a pathloss;
obtaining mapping information between the reference signal resources and values associated with the reference signal resources;
receiving, from the base station, downlink control information (DCI) including a value associated with a reference signal resource among the values associated with the reference signal resources;
estimating the pathloss based on the value associated with the reference signal resource in the DCI and the mapping information; and
transmitting, to the base station, a physical uplink shared channel (PUSCH) using at least one antenna port corresponding to the value associated with the reference signal resource in the DCI with a PUSCH transmission power determined based on the estimated pathloss.
