Abstract

A protected wireless device is avoided. An indication is received that another wireless device has detected a protected wireless device. The protected wireless device is avoided in the event the wireless device that detected the protected wireless device is within a threshold number of hops from the wireless device that received the indication.

Claims

1. A method for avoiding a protected wireless device, comprising:

receiving an indication that another wireless device has detected a protected wireless device; and

avoiding the protected wireless device in the event the wireless device that detected the protected wireless device is within a threshold number of hops from the wireless device that received the indication.

2. A method as recited in claim 1, wherein the protected wireless device includes a WiMAX wireless device.

3. A method as recited in claim 1, wherein the method is performed by an ultra wideband (UWB) wireless device.

4. A method as recited in claim 1, wherein the method is performed by an ultra wideband (UWB) wireless device, including a WiMedia UWB wireless device.

5. A method as recited in claim 1, wherein the indication is received in a beacon.

6. A method as recited in claim 1, wherein the indication is received in a beacon, the beacon includes a first information element in the event a transmitting wireless device detected a protected wireless device, and the beacon includes a second information element in the event the transmitting wireless device did not detect a protected wireless device.

7. A method as recited in claim 1, further comprising transmitting information associated with avoided band(s) and/or subcarrier(s) in the event the protected wireless device is avoided.

8. A method as recited in claim 1, further comprising transmitting information associated with avoided band(s) and/or subcarrier(s) in the event the protected wireless device is avoided, wherein the information is included in a beacon.

9. A method as recited in claim 1, further comprising transmitting information associated with avoided band(s) and/or subcarrier(s) in the event the protected wireless device is avoided, wherein the information is run length encoded.

10. A method as recited in claim 1, wherein avoiding includes passing information associated with band(s) and/or subcarrier(s) to be avoided from a media access controller (MAC) to a baseband processor.

11. A method as recited in claim 1, wherein avoiding includes passing information associated with band(s) and/or subcarrier(s) to be avoided from a media access controller (MAC) to a baseband processor, wherein the passed information is run length encoded.

12. A method as recited in claim 1, further comprising using avoidance information included in the received indication to process a received signal in the event the wireless device that detected the protected wireless device is greater than the threshold number of hops from the wireless device that received the indication.

13. A system for avoiding a protected wireless device, comprising:

a receiver configured to receive an indication that another wireless device has detected a protected wireless device; and

a transmitter configured to avoid the protected wireless device in the event the wireless device that detected the protected wireless device is within a threshold number of hops from the wireless device that received the indication.

14. A method for transmitting, comprising:

receiving, at a first wireless device, position related information from a second wireless device, wherein the first wireless device and the second wireless device are collocated;

obtaining, at the first wireless device, information specified by a regulatory agency based at least in part on the received position related information; and

transmitting in accordance with the information specified by the regulatory agency at the first wireless device.

15. A method as recited in claim 14, wherein obtaining includes retrieving from storage associated with the first wireless device.

16. A method as recited in claim 14, wherein the information specified by the regulatory agency includes a permitted transmission mask.

17. A method as recited in claim 14, wherein the information specified by the regulatory agency includes one or more permitted bands.

18. A method as recited in claim 14, wherein the position related information includes coordinates.

19. A method as recited in claim 14, wherein the position related information includes a country.

20. A method for transmitting, comprising:

receiving, at a wireless device, information associated with a mobile telephone from the mobile telephone, wherein the receiving wireless device and the mobile telephone are collocated; and

adjusting transmission at the wireless device based at least in part on the received information.

21. A method as recited in claim 20, wherein the received information includes information associated with paging time and adjusting includes suspending transmission during the paging time.

22. A method as recited in claim 20, wherein the received information includes information associated with received signal strength and adjusting includes reducing transmit power.

23. A method as recited in claim 20, wherein the received information includes information associated with received signal strength and adjusting includes avoiding frequency spectrum used by the collocated mobile telephone.
