Abstract

This disclosure provides systems, methods and apparatus for wirelessly communicating with a wireless station. In one implementation, a mobile device comprises a memory unit configured to store communication information associated with communicating on at least one channel of a wireless network. The mobile device further comprises a processing system that is configured to establish communications with the wireless station via a communication link, retrieve the communication information from the memory unit, and to provide at least a portion of the communication information to the wireless station.

First claim

What is claimed is:

1. A first mobile apparatus for wirelessly communicating with a second mobile apparatus, comprising:
a memory unit configured to store communication information associated with communicating on at least one channel of a wireless network, wherein the communication information comprises synchronization timing information for at least one base station operating on the at least one channel; and
a processing system operationally coupled to the memory unit and a transceiver, and configured to:
establish communications with the second mobile apparatus via a communication link;
retrieve the communication information from the memory unit;
provide at least one portion of the communication information to the second mobile apparatus via the wireless communication link;
receive at least one collaborative search request from the second mobile apparatus via the communication link, the collaborative search request identifying another portion of the communication information;
search for the another portion of the communication information via a channel search module; and
provide the another portion of the communication information to the second mobile apparatus via the communication link;

the channel search module operationally coupled to the processing system.

2. The first mobile apparatus of claim 1 , wherein the communication link is a peer-to-peer communication link, and wherein the first mobile apparatus provide the at least one portion of the communication information to the second mobile apparatus via the peer-to-peer communication link.

3. The first mobile apparatus of claim 1 , wherein the communication link is established via at least one access point, and wherein the first mobile apparatus provides the at least one portion of the communication information to the second mobile apparatus via the at least one access point.

4. The first mobile apparatus of claim 1 , wherein the processing system is further configured to provide at least one portion of the synchronization timing information to the second mobile apparatus.

5. The first mobile apparatus of claim 1 , wherein the communication information comprises at least one of symbol timing information, slot timing information, battery level of at least one user device, frame timing information, a primary scrambling code or a secondary scrambling code of at least one base station operating on the at least one channel, and wherein the processing system is further configured to provide at least one portion of the at least one of the symbol timing information, the slot timing formation, the battery level of at least one user device, the frame timing information, the primary scrambling code or the secondary scrambling code to the second mobile apparatus.

6. The first mobile apparatus of claim 1 , wherein the communication information comprises a list of one or more channels having received signal strength indicator (RSSI) values larger than a threshold.

7. The first mobile apparatus of claim 1 , wherein the communication information comprises location information of at least one base station, and wherein the processing system is further configured to provide at least one portion of the location information of the at least one base station to the second mobile apparatus.

8. The first mobile apparatus of claim 1 , wherein the communication information comprises pseudonoise (PN) position information of at least one base station, and wherein the processing system is further configured to provide at least a portion of the PN position information of the at least one base station to the second mobile apparatus.

9. The first mobile apparatus of claim 1 , wherein the another portion of the communication information comprises synchronization timing information of at least one base station operating on the at least one channel, and wherein the processing system is further configured to search for the synchronization timing information via the channel search module.

10. The first mobile apparatus of claim 1 , wherein the another portion of the communication information comprises at least one of symbol timing information, slot timing formation, frame timing information, a primary scrambling code or a secondary scrambling code of at least one base station operating on the at least one channel, and wherein the processing system is further configured to search for the at least one of the symbol timing information, the slot timing formation, the frame timing information, the primary scrambling code or the secondary scrambling code via the channel search module.

11. The first mobile apparatus of claim 1 , wherein the another portion of the communication information includes a list of one or more channels having received signal strength indicator (RSSI) values larger than a threshold, and wherein the processing system is further configured to search for the list of the one or more channels having good RSSI values via the channel search module.

12. The first mobile apparatus of claim 1 , wherein the another portion of the communication information comprises location information of at least one base station, and wherein the processing system is further configured to search for the location information of the at least one base station via the channel search module.

13. The first mobile apparatus of claim 1 , wherein the another portion of the communication information comprises pseudonoise (PN) position information of at least one base station, and wherein the processing system is further configured to search for the PN position information of the at least one base station via the channel search module.

14. The first mobile apparatus of claim 1 , wherein the processing system is further configured to:
receive at least one collaborative search request from one or more other mobile apparatus via another communication link, the at least one collaborative search request identifying a further portion of the communication information of the wireless network; and
determine communication information for the first mobile apparatus to search for;
determine communication information for the one or more other mobile apparatus to search for and communicate the communication information to the one or more other mobile apparatus;
determine communication information of the wireless network;
provide at least a portion of the determined communication information to the one or more mobile apparatus; and
receive communication information of the wireless network from the one of more mobile apparatus.

15. The first mobile apparatus of claim 14 , wherein determining communication information for the first mobile apparatus and the one or more mobile apparatus to search for is based at least partially on battery power level information of at least one of the first mobile apparatus or the one or more mobile apparatus.

16. The first mobile apparatus of claim 1 , wherein the processing system is further configured to send a collaborative search request to a third apparatus, the collaborative search request comprising a further portion of the communication information.

17. The first mobile apparatus of claim 16 , wherein the collaborative search request includes battery power level information of the one or more mobile apparatus.

18. The first mobile apparatus of claim 1 , wherein the communication information comprises battery power level information of at least one of the first mobile apparatus or the second mobile apparatus.

19. A method of wireless communications, the method performed by a first user equipment, comprising:
