Abstract: A channel access method and apparatus are disclosed. The channel access method by an access point (AP) having a sector antenna in a wireless local access network (WLAN), may include transmitting a sector beacon with respect to any one sector among a plurality of sectors, transmitting and receiving data with at least one station in any one sector during a pre-scheduled sector interval, sequentially performing transmission of the sector beacon and transmission and reception of the data with respect to remaining sectors of the plurality of sectors excluding the any one sector, transmitting an omni beacon with respect to all of the plurality of sectors, and transmitting and receiving data with respect to at least one station of the plurality of sectors during a pre-scheduled Basic Service Set (BSS) interval.
