Abstract
The present invention relates to a method and apparatus for interference alignment in a wireless communication system. A method in which a terminal aligns interferences in a wireless communication system, which includes a first base station governing a first cell and a second base station governing a second cell, comprises: a step in which the terminal measures a serving channel from the first base station which is a serving base station and an interference channel from the second base station; a step of transmitting null space information orthogonal to the interference channel to the first base station; a step of measuring channels from the first base station and the second base station to which an inference alignment plane generated based on the null space information is applied, and generating a receiving filter; and a step of transmitting, to the first base station, the interference alignment plane, the receiving filter, and effective channel measurement value based on the channel from the first base station.
