Abstract
A system and method of dynamic allocation of spectrum for a communication device involves receiving a user channel map (UCM) on a control channel that is outside the band of interest. The UCM can include at least boundary location information for one or more channel resources within a UHF band and communication parameters. The method can determine at least an approximate location for the communication device, compare the approximate location with the boundary location information, and determine which channels can avoid co-channel and adjacent channel interference with licensed users and other unlicensed users based on the comparison, boundary location information, and the communication parameters. The UCM can further include communication parameters such as maximum allowable transmit power, duty cycle, and in use information by other unlicensed and licensed users. The boundary location information can include polygon endpoint calculations and associated technical communication parameters.
