COGNITIVE RADIO METHOD AND APPARATUS FOR ACHIEVING AD HOC INTERFERENCE MULTIPLE ACCESS WIRELESS COMMUNICATION

摘要

In a radio network having a plurality of first users on channel (FUOCs) and one or more second users on channel (SUOCs), a method and apparatus for a SUOC to select a channel to co-occupy based upon a “selfish” goal of achieving a desired SUOC rate and an “altruistic” goal of causing low-impact on the FUOC. A SUOC collects signal parameters for a plurality of FUOCs, orders the FUOCs based upon different criteria, and attempts to co-exist with FUOCs until a suitable FUOC channel is found.

1. In a radio network having a plurality of first users on channel (FUOCs) and one or more second users on channel (SUOCs), a method comprising:
(a) identifying a plurality of FUOCs, each of the plurality of FUOCs operating in a respective FUOC channel; (b) for each of the plurality of FUOCs, determining if the SUOC can achieve a desired SUOC rate co-existing in the FUOC's channel; (c) for each of the plurality of FUOCs, determining an expected impact upon the FUOC if the SUOC were to co-exist in the FUOC's channel; (d) assigning each one of the FUOCs to one of a plurality of groups based, at least in part, upon whether the SUOC can achieve the desired SUOC rate co-existing in the FUOC's channel and the expected impact upon the FUOC if the SUOC were to co-exist in the FUOC's channel; (e) generating an ordered list of FUOCs from the plurality of groups; and (f) selecting a FUOC from the ordered list of FUOCs.
