Patent ID: 8223699

Claim:
A method of detecting and identifying spectrum opportunities, the method comprising the steps of: communicating at least 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; sensing the at least one channel from the list by the at least one node; determining if the at least one channel is in use; determining a user of each of the at least one channel that is in use; and when the at least one base station determines the user of one of the at least one channel that is being used, the at least one base station determines if the user is one of a licensed primary user, a licensed secondary user, and an unlicensed user; and if the user of the at least one channel is one of a secondary user and an unlicensed user, the node co-exists with the user in the at least one channel.
