Peer-to-peer communications enhancements
An enhanced general superframe structure for peer-to-peer communications in proximity is disclosed, which may be implemented in connection with a variety of different channel access techniques. Additionally, methods are disclosed for enabling multiple P2PNWs in proximity operating under different control schemes, including virtually centralized control, distributed control, and hybrid control, to co-exist. A hyperframe structure is also disclosed, which may comprise two or more superframes, each superframe corresponding to a different one of the corresponding P2PNW control schemes.
1. A peer device of a peer-to-peer network, the peer device comprising a processor and a memory, the memory storing computer-executable instructions which, when executed by the processor, cause the peer device to perform operations comprising:
scanning a channel to detect a first beacon of a first superframe, the first superframe being located at a beginning of a hyperframe;
decoding the detected first superframe beacon of the first superframe to locate a position of a common control and data channel (CCDCH) of the first superframe, wherein the CCDCH is configured for broadcasting at least one of control information and data packets;
sending a request message over the CCDCH of the first superframe to request the insertion of a second superframe in a reserved time of the hyperframe; and
inserting the second superframe in the reserved time of the hyperframe, the hyperframe comprising a plurality of superframes.
2. The peer device of claim 1 , wherein the hyperframe refers to a next level above the superframe in a hierarchical frame structure.
3. The peer device of claim 1 , wherein the hyperframe comprises one or more different pattern of the superframe.
4. The peer device of claim 1 , wherein the hyperframe comprises an ordered list of the plurality of superframes.
5. The peer device of claim 1 , wherein inserting the second superframe in the reserved time of the hyperframe comprises:
generating another superframe; and
generating a superframe beacon associated with the another superframe.
6. The peer device of claim 5 , wherein the first superframe and the second superframe each comprise a plurality of application frames supported by a peer-to-peer network.
7. The peer device of claim 1 , wherein the superframe beacon indicates the start of the second superframe.
8. The peer device of claim 1 , wherein the beacon of the first superframe indicates the start of the hyperframe.
9. The peer device of claim 1 , wherein the request message comprises at least one of an application identifier, application attributes, and a specification of channel resources requested by the peer.
10. A method implemented by a peer device of a peer-to-peer network, the method comprising:
scanning a channel to detect a first beacon of a first superframe, the first superframe being located at a beginning of a hyperframe;
decoding the detected first beacon of the first superframe to locate a position of a common control and data channel (CCDCH) of the first superframe, wherein the CCDCH is configured for broadcasting at least one of control information and data packets;
sending a request message over the CCDCH of the first superframe to request the insertion of a second superframe in a reserved time of the hyperframe; and
inserting the second superframe in the reserved time of the hyperframe, the hyperframe comprising a plurality of superframes.
11. The method of claim 10 , wherein the hyperframe refers to a next level above the superframe in a hierarchical frame structure.
12. The method of claim 10 , wherein the hyperframe comprises one or more different pattern of the superframe.
13. The method of claim 10 , wherein the hyperframe comprises an ordered list of the plurality of superframes.
14. The method of claim 10 , wherein inserting the second superframe in the reserved time of the hyperframe comprises:
generating another superframe; and
generating a superframe beacon associated with the another superframe.
15. The method of claim 14 , wherein the first superframe and the second superframe each comprise a plurality of application frames supported by a peer-to-peer network.
16. The method of claim 10 , wherein the superframe beacon indicates the start of the second superframe.
17. The method of claim 10 , wherein the beacon of the first superframe beacon indicates the start of the hyperframe.
18. The method of claim 10 , wherein the request message comprises at least one of an application identifier, application attributes, and a specification of channel resources requested by the peer.
19. A computer-readable storage medium comprising executable instructions that when executed by a processor cause a peer device of a peer-to-peer network to perform operations comprising:
scanning a channel to detect a first beacon of a first superframe, the first superframe being located at a beginning of a hyperframe;
decoding the detected first beacon of the first superframe to locate a position of a common control and data channel (CCDCH) of the first superframe, wherein the CCDCH is configured for broadcasting at least one of control information and data packets;
sending a request message over the CCDCH of the first superframe to request the insertion of a second superframe in a reserved time of the hyperframe; and
inserting the second superframe in the reserved time of the hyperframe, the hyperframe comprising a plurality of superframes.
20. The computer-readable storage medium of claim 19 , wherein the hyperframe refers to a next level above the superframe in a hierarchical frame structure.
