DEVICE AND METHOD FOR ESTIMATING CHANNEL IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2021/075889

A1

The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, a base station in a wireless communication system may comprise the steps of: acquiring, in a first time interval, channel information of a downlink channel with a terminal; on the basis of the unscented Kalman filter, acquiring current channel state information from previous state information and the channel information; and generating, from the current channel state information, predicted channel information in a second time interval.
