Abstract

Some demonstrative embodiments include devices, systems and/or methods of multiple-stream wireless communication. For example, an apparatus may include a wireless communication unit to perform wireless peer-to-peer (P2P) communication according to a time allocation scheme defining a plurality of scheduled allocations (teeth) for wireless P2P communication within a wireless communication network based on a predefined priority scheme, which assigns a plurality of priorities to a plurality of streams corresponding to a plurality of service types, wherein a tooth may be scheduled for P2P communication between a pair of endpoints of the wireless communication network, and wherein the tooth includes one or more contiguous portions (slices), a slice having a predefined duration allocated for communication of one or more streams having the same priority.

Claims

1. An apparatus comprising:

a wireless communication unit to perform wireless peer-to-peer (P2P) communication according to a time allocation scheme, which defines a plurality of scheduled allocations (teeth) for wireless P2P communication within a wireless communication network based on a predefined priority scheme, the priority scheme assigns a plurality of priorities to a plurality of streams corresponding to a plurality of service types,

wherein each tooth is scheduled for P2P communication between a pair of endpoints of the wireless communication network,

and wherein each tooth includes one or more contiguous portions (slices), each slice having a predefined duration allocated for communication of one or more streams having the same priority.

2. The apparatus of claim 1, wherein one or more parameters of said teeth and slices are defined based on one or more parameters of said plurality of streams.

3. The apparatus of claim 2, wherein the one or more parameters of said teeth and slices include at least one parameter selected from the group consisting of a duration of said teeth, a spacing between said teeth, a duration of said slices, and an order of said slices within said tooth.

4. The apparatus of claim 2, wherein the one or more parameters of said plurality of streams include at least one parameter selected from the group consisting of a latency parameter, a jitter parameter and a bandwidth parameter.

5. The apparatus of claim 4, wherein a duration of a slice allocated for an isochronous stream is based on a bandwidth parameter of said streams.

6. The apparatus of claim 1, wherein said slice is allocated for bidirectional P2P communication.

7. The apparatus of claim 1, wherein said wireless communication unit is to truncate a particular tooth, if there is no data to be transferred.

8. The apparatus of claim 1, wherein said wireless communication unit is to truncate a particular slice, if there is no data to be transferred.

9. The apparatus of claim 1, wherein said priority scheme assigns to an isochronous stream a priority greater than a priority of a best-effort stream.

10. The apparatus of claim 1, wherein a tooth is allocated for P2P communication between a source station and a destination station, and wherein said tooth is allocated during a contention-based-access-period (CBAP) allocated to said source and destination stations.

11. The apparatus of claim 10, wherein a slice within said tooth is allocated by a transmit-opportunity (TxOP).

12. The apparatus of claim 11, wherein said TxOP is announced by said source station, and wherein said source station is to allow said destination station to transmit during said TxOP.

13. The apparatus of claim 1, wherein said priority scheme assigns a first priority to control streams, a second priority, lesser than said first priority, to audio streams, and at least a third priority, lesser than said second priority, to other streams.

14. The apparatus of claim 13, wherein said priority scheme assigns said third priority to periodic streams, and a fourth priority, lesser than said third priority, to video streams.

15. The apparatus of claim 14, wherein said priority scheme assigns a fifth priority, lesser than said fourth priority, to high-priority internet-protocol (IP) streams, and at least a sixth priority, lesser than said fifth priority, to bulk streams and low-priority IP streams.

16. The apparatus of claim 1, wherein said time allocation scheme is allocated by a central point of said wireless communication network.

17. A method comprising:

communicating within a wireless communication network according to a time allocation scheme defining a plurality of scheduled allocations (teeth) for wireless peer-to-peer (P2P) communication based on a predefined priority scheme, which assigns a plurality of priorities to a plurality of streams corresponding to a plurality of service types,

wherein each tooth is scheduled for P2P communication between a pair of endpoints of the wireless communication network,

and wherein each tooth includes one or more contiguous portions (slices), each slice having a predefined duration allocated for communication of one or more streams having the same priority.

18. The method of claim 17, wherein one or more parameters of said teeth and slices are defined based on one or more parameters of said plurality of streams.

19. The method of claim 17 comprising allocating said slice for bidirectional P2P communication.

20. The method of claim 17 comprising truncating a particular tooth, if there is no data to be transferred.

21. The method of claim 17 comprising truncating a particular slice, if there is no data to be transferred.

22. The method of claim 17 comprising allocating a tooth for P2P communication between a source station and a destination station during a contention-based-access-period (CBAP) allocated to said source and destination stations.

23. The method of claim 22 comprising allocating a slice within said tooth by a transmit-opportunity (TxOP).

24. The method of claim 23 comprising announcing said TxOP by said source station, and allowing said destination station to transmit during said TxOP.

25. A system comprising:

at least one wireless communication device including;

one or more antennas; and

a wireless communication unit to perform wireless peer-to-peer (P2P) communication via said one or more antennas according to a time allocation scheme, which defines a plurality of scheduled allocations (teeth) for wireless P2P communication within a wireless communication network based on a predefined priority scheme, the priority scheme assigns a plurality of priorities to a plurality of streams corresponding to a plurality of service types,

wherein each tooth is scheduled for P2P communication between a pair of endpoints of the wireless communication network,

and wherein each tooth includes one or more contiguous portions (slices), each slice having a predefined duration allocated for communication of one or more streams having the same priority.

26. The system of claim 25, wherein one or more parameters of said teeth and slices are defined based on one or more parameters of said plurality of streams.

27. The system of claim 25, wherein a tooth is allocated for P2P communication between a source station and a destination station, wherein said tooth is allocated during a contention-based-access-period (CBAP) allocated to said source and destination stations, and wherein a slice within said tooth is allocated by a transmit-opportunity (TxOP).

28. A product including a non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:
