Abstract

A method and apparatus for enabling multi-band transmission includes transmitting a beacon on a first radio band and transmitting the beacon on a second radio band. The beacon includes coordination information for transmission on the first and second radio bands.

Claims

1. A method for enabling multi-band transmission, the method comprising:

transmitting a beacon on a first radio band; and

transmitting the beacon on a second radio band;

wherein the beacon includes coordination information for transmission on the first and second radio bands.

2. The method of claim 1, further comprising aligning beacon period start times across the first and second radio bands.

3. The method of claim 1, further comprising switching from the first radio band to the second radio band and monitoring for a beacon on the second radio band prior to transmitting the beacon on the second radio band.

4. The method of claim 1 wherein the first radio band is adjacent to the second radio band.

5. The method of claim 1 wherein the first radio band is not adjacent to the second radio band.

6. A method for enabling multi-band transmission, the method comprising:

a first radio of a wireless transmit/receive unit (WTRU) transmitting on a first radio band;

a second radio of the WTRU transmitting on a second radio band;

monitoring the transmission medium to determine the presence of a beacon frame;

creating a beacon period (BP) depending on the determination; and

transmitting a beacon frame on the first and second radio bands wherein the beacon frame includes synchronization information for transmission on the first and second radio bands, wherein the first radio transmits the beacon frame on the first radio band and the second radio transmits the beacon frame on the second radio band.

7. The method of claim 6, further comprising aligning a beacon period start time on the first and second radio bands.

8. The method of claim 7, further comprising configuring a BP switch information element (IE) to include synchronization information.

9. The method of claim 7, further comprising adding an expanded bandwidth transmission (EBT) BP switch IE to the beacon frame, wherein the EBT BP switch IE includes a field indicating a new beacon timing value and a time to change to a new BP.

10. The method of claim 6 wherein the beacon frame is transmitted simultaneously on the first and second radio bands.

11. The method of claim 6 wherein the beacon frame is transmitted sequentially on the first and second radio bands.

12. The method of claim 6 wherein the beacon frame includes EBT capabilities of the WTRU.

13. The method of claim 12 wherein EBT capabilities include any one of the following:

a default channel and a default expanded channel.

14. A wireless transmit/receive unit (WTRU), comprising:

a receiver;

a transmitter; and

a processor in communication with the receiver and the transmitter, the processor configured to transmit a beacon on a first radio band, and transmit the beacon on a second radio band, wherein the beacon includes coordination information for transmission on the first and second radio bands.

15. The WTRU of claim 14 wherein the processor is further configured to align beacon period start times across the first and second radio bands.

16. The WTRU of claim 14 wherein the processor is further configured to switch from the first radio band to the second radio band and monitor for a beacon on the second radio band prior to transmitting the beacon on the second radio band.

17. A wireless transmit/receive unit (WTRU), comprising:

a receiver;

a first transmitter;

a second transmitter; and

a processor in communication with the receiver and the first and second transmitters, the processor configured to control the first transmitter to transmit on a first radio band, control the second transmitter to transmit on a second radio band, monitor the transmission medium to determine the presence of a beacon frame, create a beacon period (BP) depending on the determination, and transmit a beacon frame on the first and second radio bands wherein the beacon frame includes synchronization information for transmission on the first and second radio bands, wherein the first radio transmits the beacon frame on the first radio band and the second radio transmits the beacon frame on the second radio band.

18. The WTRU of claim 17 wherein the processor is further configured to align a beacon period start time on the first and second radio bands.

19. The WTRU of claim 17 wherein the processor is further configured to configure a BP switch information element (IE) to include synchronization information.

20. The WTRU of claim 17 wherein the processor is further configured to add an expanded bandwidth transmission (EBT) BP switch IE to the beacon frame, wherein the EBT BP switch IE includes a field indicating a new beacon timing value and a time to change to a new BP.

21. The WTRU of claim 17 wherein the processor is further configured to transmit expanded bandwidth transmission (EBT) capabilities of the WTRU in the beacon frame.

22. The WTRU of claim 21 wherein the EBT capabilities include any one of the following:

a default channel and a default expanded channel.
