Abstract: Disclosed is a communication method using interference alignment in a wireless local area network (WLAN). An access point (AP) according to one embodiment may receive first channel information between a station associated with the AP and the AP and second channel information between the station and a neighboring AP to perform interference alignment in cooperation with the AP from the station, and perform interference alignment based on the first channel information and the second channel information.

Abstract: Provided are a frame transmission method performed in an access point (AP), a frame reception method performed in a terminal, and an AP. The frame transmission method performed in an AP includes acquiring a channel for transmitting a first data unit of a first terminal, when a data unit to be transmitted to at least one terminal other than the first terminal is in the AP, generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including the first data unit and the data unit to be transmitted to the at least one terminal, and transmitting the PPDU to the first terminal and the at least one terminal. Accordingly, it is possible to improve the performance of a wireless local area network (WLAN).

Abstract: Disclosed are a method for avoiding interference in a wireless local area network system and an apparatus for performing the same. The method for avoiding interference by an access point in a wireless local area network system, includes receiving channel scan results from a station associated with the access point; setting connection with an adjacent access point based on the channel scan results; determining an access point to be associated with the station through negotiation with the adjacent access point; and transmitting a reassociation request message to request reassociation with the adjacent access point to the station when the negotiation with the adjacent access point succeeds.
