Abstract

A method of dynamic station enablement procedure in a wireless local area network (WLAN) is disclosed. A method of performing an enablement procedure by a first station in a regulatory domain where a licensed device and an unlicensed device are permitted to operate together in a wireless local area network (WLAN) comprises receiving, from a second station, an enabling signal including advertisement protocol element with an advertisement protocol identification (ID) field which indicates an advertisement protocol the second station supports; and exchanging DSE (dynamic station enablement) related messages with the second station using a GAS (generic advertisement service) protocol.

Claims

1. A method of performing an enablement procedure by a first station in a regulatory domain where an unlicensed device is permitted to operate at a given time in a given geographical area with regard to a licensed device in a wireless local area network (WLAN), the method comprising:

receiving an enabling signal, including a DSE (dynamic station enablement) registered location element with a registered location DSE bit set to “

1”

, from a second station, the enabling signal informing the first station that an enablement is possible, the second station being a dependent AP (access point) station different from an enabling station, the enabling signal comprising a first enablement identifier field indicating an enablement ID allocated by the enabling station to the first station and an identifier of the enabling station other than an identifier of the dependent AP station;

transmitting a DSE (dynamic station enablement) enablement request message to the enabling station; and

receiving a DSE enablement response message from the enabling station,

wherein the DSE enablement response message includes a second enablement identifier field indicating the enablement ID allocated by the enabling station to the first station.

2. The method of claim 1, wherein:

the DSE enablement request message comprises a first query protocol element for DSE enablement request, the first query protocol element including a first information identification (Info ID);

the DSE enablement response message comprises a second query protocol element for DSE enablement response, the second query protocol element including a second Info ID; and

the first Info ID and the second Info ID are set to a value for DSE enablement.

3. The method of claim 1, wherein:

the DSE enablement response message comprises a WSM (White Space Map) element;

the WSM element comprises a channel number field and a maximum power level field;

the channel number field indicates the list of available channels; and

the maximum power level field indicates maximum allowed transmission powers of the available channels.

4. The method of claim 1, wherein the enabling signal includes DSE registered location information.

5. An apparatus of performing an enablement procedure in a regulatory domain where an unlicensed device is permitted to operate at a given time in a given geographical area with regard to a licensed device in a wireless local area network (WLAN), the apparatus comprising:

a transceiver configured to;

receive an enabling signal, including a DSE (dynamic station enablement) registered location element with a registered location DSE bit set to “

1”

, from a dependent AP (Access Point) station different from an enabling station;

transmit a DSE (dynamic station enablement) enablement request message to the enabling station; and

receive a DSE enablement response message from the enabling station, the DSE enablement response message including a second enablement identifier field indicating an enablement ID allocated by the enabling station to the first station; and

a processor configured to process the enabling signal, the DSE enablement request message, and the DSE enablement response message, the enabling signal informing the apparatus that an enablement is possible, the enabling signal comprising a first enablement identifier field indicating the enablement ID allocated by the enabling station to the first station and an identifier of the enabling station other than an identifier of the dependent AP station.

6. The apparatus of claim 5, wherein:

the DSE enablement request message comprises a first query protocol element for DSE enablement request;

the DSE enablement response message comprises a second query protocol element for DSE enablement response;

the second query protocol element includes a second Info ID;

the first query protocol element includes a first information identification (Info ID); and

the first Info ID and the second Info ID are set to a value for DSE enablement.
