Abstract

A cooperative communications manager module establishes a first wireless link with a client device using a first channel frequency and dispatches a first message to the client device over the first channel frequency. The cooperative communications manager module establishes a second wireless link with a destination node and controls the cooperative transmission of the first message simultaneously with the client device to the destination node over the second wireless link using a second channel frequency. Other embodiments are described and claimed.

Claims

1. An apparatus, comprising a cooperative communications manager module to establish a first wireless link with a client device using a first channel frequency and to dispatch a first message to said client device over said first channel frequency and to establish a second wireless link with a destination node and to control a cooperative transmission of said first message simultaneously with said client device to said destination node over said second wireless link using a second channel frequency.

2. The apparatus of claim 1, wherein said cooperative communications manager module is to establish said first wireless link with said client device using a first wireless device and is to establish said second wireless link with said destination node using a second wireless device.

3. The apparatus of claim 2, wherein said first wireless device is adapted to operate in a first wireless network and said second wireless device is adapted to operate in a second wireless network.

4. The apparatus of claim 3, wherein said first wireless network comprises any one of a wireless local area network (WLAN), wireless personal area network (WPAN), and cellular telephone network and wherein said second wireless network comprises a wireless metropolitan area network (WMAN).

5. The apparatus of claim 1, wherein said first message comprises coordination information for beam forming.

6. The apparatus of claim 5, wherein said coordination information comprises any one of uplink frame identification information, adaptive modulation and coding (AMC) band index, and channel information.

7. The apparatus of claim 1, wherein said cooperative communications manager module is to receive a second message intended for said destination node from said client device over said first wireless link using said first wireless device and is to establish a third wireless link with said destination node using said second wireless device to transmit said second message to said destination node.

8. The apparatus of claim 1, wherein said first wireless link is a point-to-point wireless link.

9. The apparatus of claim 1, wherein said first channel is an asynchronous channel.

10. The apparatus of claim 1, wherein said second channel is a synchronous channel.

11. The apparatus of claim 1, wherein the said first channel frequency and said second channel frequency are the same.

12. A system, comprising:

an antenna; and

a cooperative communications manager module to establish a first wireless link with a client device using a first channel frequency and to dispatch a first message to said client device over said first channel frequency and to establish a second wireless link with a destination node and to control a cooperative transmission of said first message simultaneously with said client device to said destination node over said second wireless link using a second channel frequency.

13. The system of claim 12, wherein said cooperative communications manager module is to establish said wireless link with said client device using a first wireless device and is to establish said second wireless link with said destination node using a second wireless device.

14. The system of claim 13, wherein said first wireless device is adapted to operate in a first wireless network and said second wireless device is adapted to operate in a second wireless network.

15. The system of claim 14, wherein said first wireless network comprises any one of a wireless local area network (WLAN), wireless personal area network (WPAN), and cellular telephone network and wherein said second wireless network comprises a wireless metropolitan area network (WMAN).

16. The system of claim 12, wherein said first message comprises coordination information for beam forming.

17. The system of claim 16, wherein said coordination information comprises any one of uplink frame identification information, adaptive modulation and coding (AMC) band index, and channel information.

18. The system of claim 12, wherein said cooperative communications manager module is to receive a second message intended for said destination node from said client device over said first wireless link using said first wireless device and is to establish said second wireless link with said destination node using said second wireless device to transmit said second message to said destination node.

19. The system of claim 12, wherein the said first channel frequency and said second channel frequency are the same.

20. A method, comprising:

establishing a first wireless link between a first client device and a second client device;

transmitting a first message from said first client device to said second client device over a first channel frequency;

establishing a second wireless link between said first and second client devices and a destination node; and

said first and second client devices cooperatively transmitting said first message to said destination node over a second channel frequency.

21. The method of claim 20, comprising establishing said first wireless link over a first wireless network, and establishing said second wireless link over a second wireless network.
