Abstract: Provided is a communication method in a wireless communication system using an interference alignment. The method includes: receiving, by a first AP, a data stream by using N1 (natural number) first reception antennas, and receiving, by a second AP, the data stream by using N2 (natural number) second reception antennas, in a wireless communication system including the first AP and the second AP which receive the data stream through a transmission beam which one or more user terminals having m (natural number) transmission antennas within a given number transmit; and updating to selectively add a part of user terminals which are newly connected to the first AP and the second AP to a set of connected user terminal, and transmitting, by each terminal of the set of connected user terminal, linearly independent transmission beams by applying an interference alignment with respect to a plurality of the first and the second reception antennas for the updated set of connected user terminal.

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.
