1. A method of transmitting a signal by a transmitting end in a wireless communication system supporting multiple antennas including a multitude of vertical domain antennas and a multitude of horizontal domain antennas, the method comprising: precoding a signal for the multiple antennas using a specific precoding matrix selected on the basis of a first codebook for a multitude of the vertical domain antennas and a second codebook for a multitude of the horizontal domain antennas; and transmitting the precoded signal to a receiving end, wherein the specific precoding matrix is defined by using a Kronecker product of a first precoding matrix selected from the first codebook according to at least one first selection vector and a second precoding matrix selected from the second codebook according to at least one second selection vector, and wherein a feedback period of the at least one first selection vector is set longer than that of the at least one second selection vector.
