Abstract: A scanning method and apparatus in wireless LAN is disclosed. The method comprises determining, by an access point (AP), whether to accommodate a station (STA) conducting an initial link setup and transmitting, by the AP, a frame to the STA, the frame including scanning redirection information for the STA to switch other channel, other band, or a neighbor AP when the AP determines not to accommodate the STA. The scanning redirection information includes a band field and a channel field. The band field indicating a band in which the STA conducts the initial link setup when the STA conducts the initial link setup from current band to the other band. The channel field indicating a channel in which the STA conducts the initial link setup when the STA conducts the initial link setup from current channel to the other channel.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for accessing a channel in a wireless LAN system. According to one embodiment of the present invention, a method for performing channel access by a station (STA) of a wireless communication system comprises: a step of receiving, from an access point (AP), information about the time window which does not allow channel access of a traffic indication map (TIM) mode STA; and a step of performing channel access based on the time window. In the event that the STA is a non-TIM mode STA, the channel access is performed in the time window. In the event that the STA is a TIM mode STA, the channel access is performed in the time interval indicated by the TIM, excluding the time window.

Abstract: The present invention relates to a wireless communication system, and more specifically, to a method and a device for updating system information in a wireless LAN system. A method for updating system information in a station (STA) of a wireless communication system, according to one embodiment of the present invention, can comprise the steps of: transmitting, by the STA which stores system information and a configuration change count value of a previously linked preferred access point (AP), a probe request frame for active scanning to the preferred AP; and receiving a probe response frame from the preferred AP. In this situation, the probe request frame includes a configuration change count field previously acquired from the preferred AP, and if a value of the configuration change count field included in the probe request frame is different from a present configuration change count value of the preferred AP, the probe response frame can include one or more elements of system information which should be updated by the STA.
