    Abstract: A method and system for managing a channel in a wireless local area network is disclosed. The method includes detecting adjacent access points, transmitting a resource allocation request frame including candidate channel information which the first access points wants to a master access point among the detected adjacent access points, receiving a resource allocation response frame which is a response with respect to the resource allocation request frame from the master access point, and configuring the BSS based on channel related information included in the resource allocation response frame. Accordingly, performance of the wireless local area network can be improved.
