    Abstract: During operation of a secondary communication system, nodes having different channel monitoring capabilities or requirements will cooperatively monitor possible frequencies for transmissions, each node using only a subset of all possible modulation sensing schemes. All nodes will share channel occupancy information to other nodes within the communication system. For example, a first group of nodes may monitor possible frequencies for television transmissions, while a second group of nodes may monitor the possible frequencies for APCO 25 transmissions. A group of nodes may also cooperatively monitor possible frequencies for more than one type of modulation transmission. Channel information will be shared among the nodes.

    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: In a cognitive radio, a method of establishing an operational policy for use in a Peer-to-Peer (P2P) group, wherein the policy can be described by layers of policy parameters with progressively higher layers having a progressively increasing number of parameters, involves determining that a policy change is to be made from a current policy (316); requesting policy information from at least one P2P group member (320); receiving a policy description from the at least one P2P group member (322); and implementing a change in the lowest layer policy parameter to establish a new operational policy (324).

    Abstract: BROADCAST SIGNAL DETECTED INDICATION SYSTEM In a radio having an in phase multiplier (A) for providing an in phase detected signal, a detection unit for receiving this signal and for determining whether this signal includes any negative polarity components which would indicate that a viable broadcast signal does not exist on the incoming frequency of interest. This detection unit can include a comparator (11) for comparing the incoming signal against a selected reference value. The invention can also include a signal quality evaluation unit (58) for providing either a digital or analog quality signal that can also effect the output and be used by appropriate processing circuitry to further refine the channel selection process.
