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, 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.

2. The method of claim 1, wherein the exchanging DSE related messages comprises

transmitting, to the second station, first query protocol element for DSE enablement request, the first query protocol element including first information (Info) ID;

and

receiving, from the second station, second query protocol element for DSE enablement response, the second query protocol element including second Info ID,

wherein the first Info ID and the second Info ID indicate information related with the first query protocol element and the second query protocol element respectively, and the first Info ID and the second Info ID are set to a value for DSE enablement.

3. The method of claim 2, wherein the second query protocol element includes white space map element including a list of available channels.

4. The method of claim 3, wherein the WSM element comprises a channel number field and a maximum power level field,

wherein 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.

5. The method of claim 1, wherein further comprising

transmitting, to the second station, a first frame to request the enabling signal using the GAS protocol.

6. The method of claim 5, wherein the enabling signal is a second frame including DSE registered location information.

7. The method of claim 1, wherein the second station is an enabling station which is a station determining available channels at its location using its own geographic location identification and a regulatory database access capability.

8. The method of claim 7, wherein the first station is a dependent station which is a station receiving an available channel list from the enabling station or a dependent AP (access point) of that enabling station that enables an operation of the dependent station.

9. A method of supporting an enablement procedure of a first station by a second 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:

transmitting, to the first 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 first station using a GAS (generic advertisement service) protocol.

10. The method of claim 9, wherein the exchanging DSE related messages comprises

receiving, from the first station, first query protocol element for DSE enablement request, the first query protocol element including first information (Info) ID;

and

transmitting, to the first station, second query protocol element for DSE enablement response, the second query protocol element including second Info ID,

wherein the first Info ID and the second Info ID indicate information related with the first query protocol element and the second query protocol element respectively, and the first Info ID and the second Info ID are set to a value for DSE enablement.

11. The method of claim 10, wherein the second query protocol element includes white space map element including a list of available channels.

12. The method of claim 9, wherein further comprising

receiving, from the first station, a first frame to request the enabling signal using the GAS protocol.

13. The method of claim 12, wherein the enabling signal is a second frame including DSE registered location information.

14. 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, from a enabling station, an enabling signal including advertisement protocol element with an advertisement protocol identification (ID) field which indicates an advertisement protocol the enabling station supports, and to exchange DSE (dynamic station enablement) related messages with the enabling station using a GAS (generic advertisement service) protocol; and

a processor configured to process the enabling signal and the DSE related messages.

15. The apparatus of claim 14, wherein the transceiver transmits first query protocol element for DSE enablement request to the enabling station, and receives second query protocol element for DSE enablement response from the enabling station,

wherein the second query protocol element including second Info ID and the first query protocol element including first information (Info) ID,

wherein the first Info ID and the second Info ID indicate information related with the first query protocol element and the second query protocol element respectively, and the first Info ID and the second Info ID are set to a value for DSE enablement.

16. The apparatus of claim 15, wherein the second query protocol element includes white space map element including a list of available channels.

17. An apparatus of supporting an enablement procedure of a dependent 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 apparatus comprising:

a transceiver configured to transmit an enabling signal including advertisement protocol element with an advertisement protocol identification (ID) field which indicates an advertisement protocol the apparatus station supports to the dependent station, and exchange DSE (dynamic station enablement) related messages with the dependent station using a GAS (generic advertisement service) protocol; and

a processor configured to generate the enabling signal.

18. The apparatus of claim 17, wherein the transceiver receives first query protocol element for DSE enablement request from the dependent station, and transmits second query protocol element for DSE enablement response to the dependent station,

wherein the second query protocol element including second Info ID and the first query protocol element including first information (Info) ID,

wherein the first Info ID and the second Info ID indicate information related with the first query protocol element and the second query protocol element respectively, and the first Info ID and the second Info ID are set to a value for DSE enablement.

19. The apparatus of claim 18, wherein the second query protocol element includes white space map element including a list of available channels.
