Abstract:
1. A method of performing an enablement procedure by a dependent station in a wireless local area network, the method comprising: receiving, from a dependent access point (AP), an enabling signal generated by an enabling station to permit the dependent station to operate TV white space; receiving, from the dependent AP, a dynamic station enablement (DSE) Link identifier element providing information on the enabling station, a MAC address of the enabling station, and a Basic Service Set identifier (BSSID) of the enabling station; transmitting a DSE enablement request frame to the enabling station, a BSSID field of the DSE enablement request frame being the same as the BSSID of the enabling station provided in the received DSE Link identifier element, a responder station address field of the DSE enablement request frame being the same as the MAC address of the enabling station provided in the received DSE Link identifier element; and receiving, from the enabling station, a DSE enablement response frame, wherein the enabling station is a station determining available channels at its location using its own geographic location identification and a regulatory database access capability, and the dependent station is a station receiving an available channel list from the enabling station or the dependent AP of the enabling station that enables an operation of the dependent station, wherein the dependent station, the dependent AP, and the enabling station are different entities, and wherein each of the dependent station and the dependent AP is enabled by the enabling station.
