1. A method of transmitting a reference signal in a wireless communication system, performed by a terminal, the method comprising:
receiving, from a base station, a synchronization signal;
receiving, from the base station, a physical broadcast channel (PBCH);
receiving, from the base station, control information,
wherein the control information includes panel identification information related to identification of a plurality of antenna panels related to transmission of the reference signal;
initializing a reference signal sequence related to generating the reference signal based on the panel identification information; and
transmitting the reference signal to the base station based on the initialized reference signal sequence,
wherein, based on a plurality of reference signals being transmitted through the plurality of antenna panels, a same scrambling sequence identifier (ID) is set to initialize each reference signal sequence for the plurality of reference signals, and
wherein each reference signal sequence is initialized to a different initialization sequence value based on the panel identification information.
