First Claim
Patent Images
1. A method for communicating between a plurality of nodes, comprising:
- observing a set of frequencies to determine spectrum awareness data for the one or more frequencies;
determining a maximum transmit power for one or more of the set of frequencies based at least in part on the spectrum awareness data;
determining one or more channels, based at least in part on the maximum transmit power for the one or more frequencies, where each channel occupies at least a portion of the set of frequencies;
selecting one or more of the channels as a bearer; and
notifying one or more other nodes of the selected bearer using an adaptive control channel.

Abstract
Communicating between a plurality of nodes includes scanning a set of frequencies to determine spectrum awareness data for one or more frequencies; determining a maximum transmit power for one or more of the frequencies based at least in part on the spectrum awareness data for the frequencies; determining one or more channels, each channel occupying at least a portion of the set of frequencies; and selecting one or more of the one or more channels as a bearer.
