First Claim
Patent Images
1. A wireless apparatus comprising:
- an adaptive channelization controller to determine which of a plurality of predetermined sub-channels to use to support a multicarrier wireless link, based on channel state information; and
a receiver chain to process a received multicarrier signal associated with said multicarrier wireless link based on control information output by said adaptive channelization controller.

Abstract
Adaptive channelization is achieved in a high throughput multicarrier system by first subdividing a high throughput channel into a number of frequency sub-channels. A channelization decision may then be made within a device as to which of the sub-channels to use for a corresponding high throughput wireless link based on channel state information.
