    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.

    Abstract: Disclosed are an active scanning method and an active scanning device. The active scanning method in a wireless LAN comprises the steps of: a second station (STA) receiving a first probe request frame which has been broadcast by a first STA; and the second STA broadcasting a second probe request frame. The second probe request frame may include a probe request frame detection field, and the probe request frame detection field may indicate that the second STA has received the first probe request frame. Accordingly, a probe response frame is broadcast to a plurality of STAs, thus simplifying a scanning procedure.

    Abstract: The present invention relates to a method and apparatus for associating a station (STA) with an access point (AP). The method for associating a first AP with an STA in a wireless LAN includes the steps of: a first AP receiving an association request frame from the STA; the first AP requesting authentication information on the STA from a second AP with which the STA was previously associated; the first AP receiving authentication information on the STA from the second AP, wherein the first and second AP's are linked by a distribution system, the association request frame includes identification information on the second AP, and the authentication information on the STA can include at least one of a paired main key (PMK) and a recertification main session key (rMSK). Accordingly, fast association between the STA and the AP can be achieved by a simplified authentication procedure without repeating a full authentication procedure.
