Abstract

A system and method for multiband rate scaling for communication, particularly wireless communication. A band is used as a parameter for wireless communication performance when a wireless communication channel has a plurality of available bands for communication. A selected communication band may be switched to another available communication band, where the switching may be based on a desired performance determination.

Claims

1. A method comprising:

determining by a client device a plurality of available bands for wireless communication with an access device;

communicating with said access device over a first band of said plurality of available bands;

monitoring a performance parameter of communication over said first band;

comparing a value of said performance parameter to a threshold value of said performance parameter; and

based on said comparison, selecting a second band of said available bands for communication with said access device, notifying said access device of said selection, and communicating with said access device over said second band.

2. The method of claim 1, wherein determining said plurality of available bands for wireless communication comprises communicating with said access device over a third band, different from said first and second bands.

3. The method of claim 2, wherein said third band is reserved for communications regarding availability of said available bands.

4. The method of claim 1, wherein determining said plurality of available bands for wireless communication comprises communicating with said access device over said first band.

5. The method of claim 1, wherein determining said plurality of available bands for wireless communication with said access device comprises communicating with said access device according to a predetermined signaling protocol.

6. The method of claim 1, wherein said threshold vale of said performance parameter is dynamically changed by said client device, the method further comprising notifying the access device of changes in said threshold value.

7. The method of claim 1, wherein said threshold value of said performance parameter is dynamically changed by said access device, the method further comprising notifying the client device of changes in said threshold value.

8. A system comprising:

a client device capable of wirelessly communicating with an access device over a plurality of bands, wherein said client device is to;

determine a plurality of bands available for wireless communication with said access device;

communicate with said access device over a first band of said plurality of available bands;

monitor a performance parameter of communication over said first band;

compare a value of said performance parameter to a threshold value of said performance parameter; and

based on said comparison, select a second band of said available bands for communication with said access device, notify said access device of said selection, and communicate with said access device over said second band.

11. The system of claim 8, wherein said client device is to determine said plurality of bands available for wireless communication with said access device in accordance with a predetermined signaling protocol.

12. The system of claim 8, wherein said client is further to change said threshold value of said performance parameter, and to notify said access device of said change.

13. The system of claim 8, wherein said client is further to receive notification from said access device of a change to said threshold value of said performance parameter.

9. The system of 1, wherein said client device is further to determine said plurality of available bands for wireless communication by communicating with said access device over a third band, different from said first and second bands.

10. The system of 1, wherein said client device is further to determine said plurality of available bands for wireless communication by communicating with said access device over said first band.
