A scanning method in a wireless local area network (WLAN), a station supporting the scanning method, and a new type of interworking information element format including information about a distribution system (DS) are disclosed. In the scanning method, information about a DS is included in a beacon frame or a probe request frame/frame response frame. Such information about the DS may be included in a network type field of for example, an interworking information element. In an active scanning method, a user equipment (UE) may specify its DS type by transmitting a probe request frame including DS information such as the DS type or the like. In a passive scanning method, the UE may select a suitable AP by using DS information such as a DS type included in the beacon frame or the like. The DS type may be information indicating whether a DS is a wireless network such as a mesh network or any other wired network.
