Abstract
A system (10) and method (50) of dynamic allocation of spectrum for a communication device involves receiving (51) 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. The method can determine (52) at least an approximate location for the communication device, compare (56) the approximate location with the boundary location information, and determine (57) which channels can avoid co-channel and adjacent channel interference with licensed users and other unlicensed users based on the comparison. The method can relax communication parameters for the one or more channel resources if no licensed user signals are found in the user channel map, and tightening the communication parameters if co-channel, adjacent channel, or other interference generating channel use is found within the user channel map.
