摘要
Disclosed is a method for a terminal to report channel state information to a base station in a wireless communication system. The method comprises the steps of: receiving a first reference signal and a second reference signal which are cyclically beamformed in different directions in a predetermined resource unit from the base station; and reporting the channel state information to the base station on the basis of the first reference signal and the second reference signal, wherein the channel state information comprises a first precoder group corresponding to the first reference signal and a second precoder group corresponding to the second reference signal.
