Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to various embodiments of the present disclosure, a method performed by a base station in a wireless communication system may comprise: acquiring, on the basis of a CSI report in a first time period, channel information including current channel state information (CSI) from a terminal; identifying, on the basis of the channel information, a spatial domain (SD) component, a frequency domain (FD) component, and a linear combination (LC) coefficient value mapped to the SD component and the FD component used for compression; acquiring a filtered LC coefficient value on the basis of a Kalman filter, and generating predicted channel information in a second time period on the basis of the SD component, the FD component, and the filtered LC coefficient value.
