Abstract
Disclosed is a method for scanning for an access point in a wireless LAN system. An active scanning method comprises the steps of: transmitting a probe request frame to an access point; and receiving, from the access point, a probe response frame corresponding to the probe request frame. The probe response frame may include time information of a beacon transmitted after the probe response frame. Thus, the efficiency of a wireless channel can be improved in a wireless LAN system.
