摘要： 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.

摘要： Efficient frequency spectrum sharing between at least one incumbent communication system(s) (102, 152) and at least one cognitive radio (CR) system (105) is provided. The incumbent system's system parameters and CR system's operational requirements are copied to a mirrored database (106B). The mirrored database (106B) is controlled by a either a central authority (108) or a database manager having delegated authority (508). The mirrored database (106B) is accessed by the CR system (105). The mirrored database (106B) can be modified and updated by the central authority (108) or delegated database manager (508) to correct for interference detected in the incumbent system caused (152) by the cognitive radio system (105). The cognitive radio system (105) utilizes the updated mirrored database (106B) to avoid interfering with the incumbent system (102, 152) to determine CR system operating parameters thus enhancing the ability to share spectrum.

摘要： Allocation of channels in a dedicated frequency spectrum on a secondary basis. A direct mode communication request (150) from a first wireless communication device (112) can be received and processed to determine whether there are one or more secondary communication channels over which direct mode communication may be implemented between the first wireless communication devices and other wireless communication devices (114, 116, 118) without violating at least one communication policy for the secondary communication channel. Use of a secondary communication channel can be assigned or denied. In addition, a direct mode communication request can be communicated from a wireless communication device to a base transceiver station (104) identifying one or more other communication devices for which direct mode communication is requested.

摘要： A method (300, 400) and a communication system (104, 106, 200) for dynamic RF spectrum allocation among a plurality of RF transmitters (108, 110, 112). A message can be received from a first communication system. The message can include a request (130) for available RF spectrum over which to transmit RF signals. The message can indicate a geographic location of a first non-incumbent transmitter (112) associated with the first communication system. Further, for the RF spectrum, a maximum power level can be determined at which the first non-incumbent transmitter may transmit without exceeding a threshold level of interference at least one focal point (134). A RF spectrum list (138) identifying at least the RF spectrum and the determined maximum power level can be communicated to the first communication system.
