  • Publication number: 20110014936
    Abstract: A method for facilitating radio communications includes receiving, at a first cognitive station (CS) from a cognitive central station (CCS), a message having a candidate list of one or more candidate frequencies, such that each frequency of the candidate list is a frequency at which each of a terminal, the CCS, and a primary station in communication range of the terminal is configured to operate. Further operations include measuring an availability of a frequency of the candidate list to form a first transmission parameter, determining, based upon the transmission parameter, a target frequency list indicating which frequency or frequencies of the candidate list is available for communication between the terminal and the CCS, and providing, to the terminal, an allocation message identifying one or more frequencies of the target frequency list at which the terminal is permitted to communicate with the CCS.
