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 spatial relation information between a plurality of reference signals (RSs) and a sounding reference signal (SRS), and configuration information for the SRS, wherein at least one SRS is transmitted in a different time resource;
based on the spatial relation information, identifying a first downlink RS for a first time resource and a second downlink RS for a second time resource;
transmitting, to the base station, a first SRS on the first time resource based on the first downlink RS;
transmitting, to the base station, a second SRS on the second time resource based on the second downlink RS;
receiving, from the base station, a channel state information-reference signal (CSI-RS) on a third time resource based on a first transmission configuration indicator (TCI) state; and
receiving, from the base station, a CSI-RS on a fourth time resource based on a second TCI state,
wherein the third time resource includes the first time resource and the second time resource,
wherein the third time resource is allocated for a cross division duplex (XDD),
wherein the plurality of RSs includes the first downlink RS and the second downlink RS,
wherein the configuration information includes information on the first time resource associated with the first downlink RS and information on the second time resource associated with the second downlink RS,
wherein the RRC message includes quasi-co location (QCL) information between the CSI-RS and a plurality of TCI states including the first TCI state and the second TCI state, and
wherein the fourth time resource is allocated for a downlink reception.
