Zusammenfassung:	Disclosed is a method for estimating a channel of a terminal by a base station in a wireless communication system supporting multiple antennas, the method comprising the steps of: estimating a moving speed of the terminal on the basis of a first channel value acquired at a current time point and a second channel value acquired at a previous time point; determining, on the basis of the estimated moving speed, a complexity degree corresponding to the number of channel values for multiple time points including the current time point; and estimating a channel of the terminal at a next time point on the basis of the determined complexity degree.
