Abstract
A method by which a base station transmits a signal on the basis of an antenna array in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: determining a multi-rank beam in consideration of (i) positions of a plurality of terminals and (ii) positions of null points of a beam generated through the antenna array; and transmitting signals to the plurality of terminals by using the multi-rank beam. The antenna array may be based on a three-dimensional shape having omnidirectional symmetry, and the positions of the null points and the positions of the plurality of terminals may be configured on the basis of a polar coordinate system using the center of the antenna array as an origin point.
