    摘要: The presence of the non-television transmission within a channel is used to indicate that secondary non-licensed usage of the channel is permitted. Specifically, if secondary users incorporate the means to identify the unique modulation signature of the secondary user, decoding of a beacon signal may not be necessary. With the above in mind, a radio will be prevented from transmitting within a frequency band when no transmission within the licensed spectrum is currently taking place; the licensee is currently transmitting on the spectrum (e.g., television transmissions are taking place utilizing the spectrum, or the radio cannot sense the presence of a data channel (beacon).

    摘要: During operation of a secondary communication system, cells (106) are formed by a plurality of localized nodes (104) to alert other nodes within the cell of frequencies which must be protected or otherwise avoided. All nodes within the cell monitor a differing subset of all frequencies available, and share information with respect to acceptable and protected frequencies with each other via low-power, short-range communication. Each node then forms a list of available channels for communication, and chooses a single node to report this information back to controller.

    摘要: A method and apparatus for allocation of shared spectrum in a wireless communication system uses a radio frequency (RF) beacon signal that is transmitted between access points of the wireless communication system. The information content of the RF beacon signal includes an identifier of the access point that generated the signal, identifiers of clients of that access point; and identifiers of the communication channels assigned to those clients. The client identifier may include at least part of an Internet Protocol (IP) address of the client. Additionally the beacon signal may contain client attributes to enable negotiation of the sharing of available communication channels between access points and clients.

    摘要: A method and apparatus for allocating spectrum within a wireless communication system is provided herein. During operation, a first base station will determine a location of a UE wishing to transmit. A database will be accessed containing wireless coverage area information for base stations with overlapping coverage with the first base station. Based on this information the first base station will determine if the UE is within an overlapping coverage area of multiple base stations. Spectrum will be assigned to the wireless equipment in a guard band, based at least in part on the determination that the UE is not within the overlapping coverage area.

    摘要: A method, wireless controller, and information processing system that define communication channel allocation. Communication channel allocation commands associated with a first network are monitored (102). The first network (102) comprises a plurality of communication frequencies assigned by the communication channel allocation commands. A set of communication frequencies are determined that have been assigned to wireless devices (108) associated with the first network (102) in response to the monitoring. A specification of unused communication frequencies within the plurality of communication frequencies are transmitted to a second network (104) in response to the determining.
