Abstract

The present invention provides methods of managing interference in a wireless communication system. The methods may include receiving information indicative of a portion of an interfering signal received by a first wireless communication device, decoding the portion of the interfering signal, and providing at least one back-off instruction destined for a second wireless communication device based on the decoded portion of the interfering signal.

Claims

1. A method, comprising:

receiving, at a server, information indicative of at least a portion of an interfering signal received by a first wireless communication device, the interfering signal being transmitted by a second wireless communication device;

determining, at the server, an identity of the second wireless communication device by decoding the received portion of the interfering signal using at least one protocol used to encode the interfering signal; and

providing, from the server at least one back-off instruction destined for the second wireless communication device using the identity of the second wireless communication device.

2. The method of claim 1, wherein receiving the information indicative of the portion of the interfering signal comprises receiving at least one packet including encapsulated information indicative of the portion of the interfering signal.

3. The method of claim 1, wherein decoding the portion of the interfering signal comprises determining that the interfering signal is an encoded signal provided by the second wireless communication device.

4. The method of claim 3, wherein decoding the portion of the interfering signal comprises determining that the interfering signal is an encoded signal provided by a hidden wireless communication device.

5. The method of claim 3, wherein decoding the portion of the interfering signal comprises determining said at least one protocol that the second wireless communication device used to encode the interfering signal.

6. The method of claim 5, wherein determining said at least one protocol comprises determining said at least one protocol based on at least one protocol library maintained at the server.

7. The method of claim 5, wherein determining said at least one protocol comprises determining said at least one protocol using information indicative of said at least one protocol provided by the first wireless communication device.

8. A method, comprising:

receiving, at a first wireless communication device, an interfering signal;

determining, at the first wireless communication device, whether the interfering signal was received from at least one second wireless communication device;

providing, from the first wireless communication device to a server, samples of at least a portion of the interfering signal in response to determining that the interfering signal was received from said at least one second wireless communication device; and

receiving at the first wireless communication device and from the server, information indicative of at least one back-off instruction destined for said at least one second wireless communication device.

9. The method of claim 8, wherein determining whether the interfering signal was provided by said at least one second wireless communication device comprises comparing the interfering signal strength with an ambient noise level.

10. The method of claim 9, wherein determining whether the interfering signal was provided by said at least one second wireless communication device comprises determining that the interfering signal was provided by said at least one second wireless communication device when the interfering signal strength exceeds the ambient noise level.

11. The method of claim 8, comprising forming the samples by sampling a portion of the interfering signal.

12. The method of claim 11, wherein providing the samples of the interfering signal comprises forming at least one packet by encapsulating the samples.

13. The method of claim 12, wherein providing the samples of the interfering signal comprises providing said at least one packet including encapsulated samples to the server.

14. The method of claim 8, comprising providing, from the first wireless communication device, said at least one back-off instruction to said at least one second wireless communication device.
