1. A method performed by a base station (BS) in a wireless communication system, the method comprising:
acquiring channel information for a downlink channel with a user equipment (UE) in a first time interval;
acquiring current channel state information from previous state information and the channel information, based on an unscented Kalman filter (UKF); and
generating predicted channel information in a second time interval from the current channel state information,
wherein the generating of the predicted channel information comprises acquiring a time delay parameter and a Doppler parameter of the current channel state information and generating the predicted channel information, based on the time delay parameter, the Doppler parameter, and resource difference information, and the resource difference information includes a time difference between first time-frequency resources and second time-frequency resources and a frequency difference between the first time-frequency resources and the second time-frequency resources.
