Disclosed in the present application is a method for a receiving end to report feedback information to a transmitting end in a wireless communication system. Specifically, the method comprises receiving, from a base station, a plurality of reference signals corresponding to a two-dimensional antenna array; determining the number of horizontal antenna ports and the number of vertical antenna ports which reflect the mobility of a receiving end, by using the horizontal channel and the vertical channel estimated based on the plurality of reference signals; calculating a horizontal dimensional control matrix and a vertical dimensional control matrix by using the determined numbers of horizontal antenna ports and vertical antenna ports; determining and reporting a horizontal precoding matrix, a vertical precoding matrix, and a three-dimensional channel link by using the horizontal dimensional control matrix, the vertical dimensional control matrix, the horizontal channel and the vertical channel.
