Abstract

The methods and an apparatuses for scanning in WLAN are disclosed. A method of a scanning of a station (STA) may include monitoring a channel during a probedelay based on a MAC sublayer management entity (MLME)-SCAN.request primitive indicating an active scanning for a target Access Point (AP), receiving a frame including a channel congestion indicator from an AP during the probedelay, generating a MLME-SCAN.change request primitive to request a change of a scanning type parameter included in the MLME-SCAN.request primitive when the channel congestion indicator indicates that the channel is congested, generating a MLME-SCAN.change confirm primitive to confirm the change of the scanning type parameter included in the MLME-SCAN.request primitive as a response of the MLME-SCAN.change request primitive, and performing a passive scanning for the target AP based on the MLME-SCAN.change confirm primitive.
