METHOD AND SYSTEM ENABLING USE OF WHITE SPACE RADIO SPECTRUM USING AN OUT OF BAND CONTROL CHANNEL
First Claim
1. A method of dynamic allocation of spectrum for a communication device where a band of radio frequencies is used with a local, regional, or national frequency allocation that leads to a subset of the bands containing unused or available frequencies in any geographic area, but not all channels are used in all markets due to the need to protect receivers from interference from other stations, comprising the steps of:
- receiving an user channel map on a control channel that is outside the band of interest, containing at least boundary location information for one or more channel resources within a UHF band and communication parameters;
determining at least an approximate location for the communication device;
comparing the approximate location with the boundary location information; and
determining 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.

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 within a UHF band and communication parameters. 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, 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.
