The present application discloses a method for transmitting, at a transmitting end, a signal to a receiving end in a wireless communication system. Specifically, the method for transmitting a signal comprises the steps of: receiving preferred beam identifier information from a representative receiving end of a plurality of receiving ends comprising the receiving end; configuring, on the basis of the preferred beam identifier information, a first precoder for aiming the direction of the signal in a first beam direction and a second precoder for aiming the direction of the signal in the direction of the receiving end with respect to the first beam direction; and transmitting the signal to the receiving end using a hybrid beamformer comprised of the first precoder and the second precoder.
