Claim Text:
1. A backhaul radio for exchanging one or more data interface streams with one or more other backhaul radios, said backhaul radio comprising: a plurality of receive radio frequency (RF) chains, wherein each receive RF chain is configured to convert from a respective one of a plurality of receive RF signals within a receive frequency band to a respective one of a plurality of receive chain output signals, and wherein each said respective one of the plurality of receive RF signals is characterized by a receive channel combination from amongst a plurality of possible receive channel combinations, each said receive channel combination comprising at least a receive channel center frequency from amongst one or more possible receive channel center frequencies and a receive channel bandwidth from amongst one or more possible receive channel bandwidths; a plurality of transmit radio frequency (RF) chains, wherein each transmit RF chain is configured to convert from a respective one of a plurality of transmit chain input signals to a respective one of a plurality of transmit RF signals within a transmit frequency band, and wherein each said respective one of the plurality of transmit RF signals is characterized by a transmit channel combination from amongst a plurality of possible transmit channel combinations, each said transmit channel combination comprising at least a transmit channel center frequency from amongst one or more possible transmit channel center frequencies and a transmit channel bandwidth from amongst one or more possible transmit channel bandwidths; and a plurality of directive gain antenna elements; wherein the backhaul radio is configured to transmit and receive coincident in time for at least a period of time; wherein the backhaul radio is configured to determine a measure of interference associated with at least one or more receive channel combinations; wherein the backhaul radio is configured to determine the measure of interference during a blanking interval in which the one or more other backhaul radios are assumed to substantially inhibit transmissions within at least one or more frequency channels corresponding to the at least one or more receive channel combinations; wherein the backhaul radio is configured to determine or estimate one or more performance metrics associated with the at least one or more receive channel combinations, said determining or estimating of the one or more performance metrics being based at least upon the measure of interference; and wherein the backhaul radio is configured to change at least one or more of the plurality of receive RF signals from being characterized by a first receive channel combination to being characterized by a second receive channel combination, said changing being based at least upon an opportunity to improve at least one of the one or more performance metrics.
