Disclosed in the present application is a method for a transmitting end transmitting a signal in a wireless communication system. Specifically, the method comprises the steps of: transmitting, to a receiving end, a first reference signal for providing a reference beam which is equal in all directions, and a second reference signal for providing a boundary beam which heads toward a pre-set direction; receiving, from the receiving end, feedback information on the difference value between the reference beam gain and the boundary beam gain; estimating the mobility information of the receiving end on the basis of the amount of change in the difference value; and, by using the mobility information, performing beamforming for transmitting a signal to the receiving end. |
