A method, system and apparatus for managing communication in a Public Safety Communication Network (PSCN). The PSCN includes a plurality of Mobile Stations (MSs) () and a master controller (). The method includes initiating a communication between one or more MSs and the master controller using a primary channel (). The primary channel corresponds to a primary frequency spectrum in the PSCN. The method further includes identifying one or more available channels in one or more of the primary frequency spectrum and a secondary frequency spectrum (). Each of the primary frequency spectrum and the secondary frequency spectrum include one or more channels. Thereafter, a channel hopping pattern is generated for one or more MSs based on one or more available channels (). The channel hopping pattern corresponds to a sequence of frequency hops for a MS.

A method () and apparatus () for detecting and identifying spectrum opportunities, including the steps of communicating a location of at least one node () to at least one base station () (), transmitting a list of at least one channel from the at least one base station () to the at least one node () (), and sensing the at least one channel from the list by the at least one node () (). The method () also includes the steps of determining if the at least one channel is in use, and if the at least one channel is in use, determining the user of the at least one channel that is in use ().

Method and apparatus for detecting and identifying spectrum opportunities

A wireless communication network is provided in which a plurality of radio devices achieve frequency diversity. By utilizing cognitive capability within the radio devices to iteratively select frequency sets, a lowest cardinality frequency set is generated and used to communicate amongst the plurality of radio devices. Each radio device can have different hardware, as the iterative selection of frequency set can take into account the different hardware capabilities of the radio devices.
