1. A method performed by a first terminal in a wireless communication system, the method comprising:
receiving, from a second terminal via a PC5-radio resource control (RRC) signaling, first information on a channel state information-reference signal (CSI-RS) for sidelink (SL) and second information on a latency bound of a channel state information (CSI) report for the SL:
receiving, from the second terminal, the CSI-RS for the SL based on the first information:
receiving, from the second terminal, control information to trigger the CSI report associated with the CSI-RS;
identifying a time at which the triggered CSI report is transmitted;
in case that the time does not exceed a valid SL CSI window, transmitting, to the second terminal, the triggered CSI report; and
in case that the time exceeds the valid SL CSI window, cancelling the triggered CSI report,
wherein the valid SL CSI window is determined based on the latency bound which is configured by the PC5-RRC signaling.
