    Abstract: A technique for a secondary communication system to utilize spectrum designated to another (or primary) communication system is provided. By ranking a plurality of secondary base stations based on base station transmit power, calculated required transmit power and path loss, a set of criteria is developed for selecting a highest ranked secondary base station for operation within a primary's spectrum. The ranking may be adapted based on mobility of the secondary's subscriber; and as such the secondary system communicates within the primary's spectrum using the adaptively ranked base stations. Channel selection may also be ranked. The technique and apparatus allows a cognitive radio (CR) network to operate within an incumbent network's spectrum.

    Abstract: A method and apparatus for allowing communication units (100) to utilize non-licensed spectrum is provided herein. In particular, when a radio (100) determines a need to transmit within non-licensed spectrum, the radio (100) searches for a beacon being transmitted (303). The beacon identifies a priority of the current user of the non-licensed spectrum (305). If the radio's (100) priority is higher than the current user of the non-licensed spectrum, or if no beacon is heard, the radio (100) may begin transmitting within the non-licensed spectrum (311). As part of the radio's (100) transmission, a beacon will be broadcast by the radio (100) identifying the radio's (100) priority.

    Abstract: A method of determining operating parameters for a secondary system transmitter is described. The transmitter characteristics, including location and operating frequency band, are provided to a geo-location database. The database determines the maximum allowable transmission power that meets various specifications for different channels and conveys the power and channel(s) to the transmitter. The database estimates channel incumbent signal strengths based on the transmitter location and primary and higher-priority secondary incumbent systems, estimates the splatter levels, determines whether adjacent and co-channel interference protection ratios are met, and adjusts the allowable power level accordingly. The database also estimates aggregate co- and adjacent channel primary and secondary incumbent system interference levels at the transmitter location and predicts channel quality for each allowable channel. The estimated levels are updated using measurements of actual levels at the transmitter location. The database dynamically allocates channels using the secondary system priorities.
