1. A method, performed by a terminal, of identifying a channel state information (CSI) processing unit occupation time in a wireless communication system, the method comprising:
receiving, from a base station, information indicating activation of a semi-persistent CSI report through downlink control information (DCI) or a medium access control (MAC) control element (CE);
receiving, from the base station, at least one CSI-reference signal (RS) for the semi-persistent CSI report; and
identifying the CSI processing unit occupation time for the semi-persistent CSI report based on at least one of a reception time point of the information indicating the activation of the semi-persistent CSI report or a reception time point of the at least one CSI-RS,
wherein the identifying of the CSI processing unit occupation time comprises identifying, as a start time point of the CSI processing unit occupation time, a time point after an MAC CE activation delay, which is a time required for the MAC CE to be applied to the terminal, from a time point when a hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission for the MAC CE indicating the activation of the semi-persistent CSI report ends.
