Abstract
A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device, determining (52) which UHF television broadcast channels are available for use by the user device and determining (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.

A method of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting, comprising:
- determining, by a user device, a location of a user device;
- determining a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels;
- transmitting, by the user device, the maximum allowed transmission power and location determined by the user device to a remote server for sharing information with other devices;
- and
- determining which UHF television broadcast channels are available for use by the user device for white space reception for a given location based on the location of the user device, polygon endpoints received from a television broadcast, and signal strength measurements for co-channel and adjacent channels.
A system of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting, comprising:
- a transceiver;
- a memory storing computer instructions;
- and a processor coupled to the transceiver and the memory, wherein the processor, responsive to executing the computer instructions, causes the processor to perform operations comprising:
- determining a location of a user device;
- determining which UHF television broadcast channels are available for use by the user device for white space reception for a given location based on at least the location of the user device, polygon endpoints defining a location of usable reception of the television broadcast, and signal strength measurements for co-channel and adjacent channels;
- determining a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels;
- and
- transmitting the maximum allowed transmission power and location by the user device to a remote server.
A method of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting, comprising:
- determining, by a user device, a location of the user device;
- receiving, by the user device, data defining polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast;
- determining, by the user device, a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels;
- and
- determining, by the user device, which UHF television broadcast channels are available for use for white space reception by the user device for a given location based on the location of the user device, the polygon endpoints, and signal strength measurements for co-channel and adjacent channels.
