    Abstract: The present invention relates to a wireless communication system, and a method and apparatus for controlling channel access in a wireless LAN system. The method for controlling the channel access of a station (STA) of a wireless communication system according to the present invention comprises detecting a short frame transmitted by another STA; and deferring the channel access of the STA by a predetermined length of time. The short frame is a frame that triggers a service period during which the transceiving of a plurality of data frames of the other STA is allowed. The predetermined length of time can be set to the value corresponding to the length of time ranging from the start of the service period to the point in time at which the transceiving of a first data frame from among the plurality of data frames of the other STA is completed.

    Abstract: The present invention relates 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 may comprise 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. Preferably, 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 may include one or more elements of system information which should be updated by the STA.

    Abstract: Disclosed are a method and an apparatus for scanning in a wireless LAN. The method may comprise the following steps: an STA determining identifier information of an AP to be included in a probe request frame as a wildcard SSID and a wildcard BSSID, based on a first MLME; the STA receiving from the AP a frame including information on the BSSID of the AP and the SSID of the AP before a probe delay time expires; the STA determining wither the AP is a target AP based on the BSSID and the SSID; the STA redetermining the identifier information of the AP to be included in the probe request frame based on the BSSID and the SSID, when the AP is the target AP; and the STA unicasting a probe request frame that is re-determined based on the BSSID and the SSID.
