Abstract: Provided is a communication method in a wireless communication system using interference alignment. The method includes: transmitting a transmission beam for separated data stream to N1 (natural number) user terminals by using M1 (natural number) antennas, by a first AP in a downlink cell; and receiving a reception beam for separated data stream from N2 (natural number) user terminals by using M2 (natural number) antennas, by a second AP in an uplink cell, wherein the first AP transmits linear independent transmission beams to improve a degree of freedom while the second AP simultaneously receives orthogonal reception beams, by simultaneously reflecting interference alignment between two cells including downlink and uplink cells.
