Abstract
Disclosed is a method for reporting channel quality information by a terminal to a base station in a wireless communication system to which hybrid beamforming is applied. Particularly, the method comprises the steps of: obtaining information associated with a first precoder for first beamforming from among hybrid beamforming; calculating information associated with a second precoder for second beamforming by receiving, from the base station, a reference signal to which the first beamforming is applied; calculating channel quality information by assuming that a pre-compensation precoder and the second precoder are applied; and reporting the channel quality information to the base station.
