Abstract: Disclosed are a method and apparatus for an access point (AP) to control channel access of a station in a wireless local area network (WLAN) system. An AP according to one embodiment may determine resource allocation information for protecting a resource for a station not referring to traffic indication map (TIM) information. The determined resource allocation information is transmitted to a station referring to the TIM information, and the station referring to the TIM information does not conduct channel access in a time period specified in the resource allocation information.
