Claims22
A method for a station, permitted to operate within available channels not used by a licensed device, to select a channel to begin a transmission of signals in a Wireless Local Area Network (WLAN), the method comprising:
- transmitting a first frame comprising an information element whose element ID indicates a specific protocol related to a registered location query, wherein the information element comprises information on a geographical location of the station;
- receiving a second frame comprising a result of the query and information for the available channels based on the information on the geographical location of the station in a form of a White Space Map (WSM);
- and
- selecting a channel among the available channels to begin the transmission of signals in the WLAN according to the received WSM.
A station device permitted to operate within available channels not used by a licensed device, and configured to select a channel to begin a transmission of signals in a Wireless Local Area Network (WLAN), the station device comprising:
- a transmitter configured for transmitting a first frame comprising an information element whose element ID indicates a specific protocol related to a registered location query, wherein the information element comprises information on a geographical location of the station device;
- a receiver configured for receiving a second frame comprising a result of the query and information for the available channels based on the information on the geographical location of the station device in a form of a White Space Map (WSM);
- and
- a processor operably connected to the transmitter and the receiver and configured for selecting a channel among the available channels to begin the transmission of signals in the WLAN according to the received WSM.
