METHOD AND APPARATUS FOR DETECTING AND IDENTIFYING SPECTRUM OPPORTUNITIES
First Claim
1. 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; and
determining a user of each of the at least one channel that is in use.

Abstract
A method (20,200) and apparatus (10) for detecting and identifying spectrum opportunities, including the steps of communicating a location of at least one node (12) to at least one base station (14) (24), transmitting a list of at least one channel from the at least one base station (14) to the at least one node (12) (26), and sensing the at least one channel from the list by the at least one node (12) (34). The method (20,200) also includes the steps of determining if the at least one channel is in use, and if the at least one channel is in use, determining the user of the at least one channel that is in use (38).

13. A method of detecting and identifying spectrum opportunities, the method comprising the steps of:
-
providing a plurality of nodes in communication with at least one base station; communicating a location and a velocity of each of the plurality of nodes to the at least one base station; determining a list of a plurality of channels by the at least one base station, wherein the list includes a signal indicator associated with each of the plurality of channels; transmitting the list of the plurality of channels from the at least one base station to the plurality of nodes; sorting the plurality of channels based upon the signal indicator by each of the plurality of nodes; sensing the plurality of channels from the list by each of the plurality of nodes; configuring at least one of the hardware and software of each of the plurality of nodes for each of the plurality of channels based upon the signal indicator; determining soft information for the plurality of channels by the plurality of nodes; transmitting the soft information from the plurality of nodes to the at least one base station; determining if each of the plurality of channels are in use; and determining a user for each of the plurality of channels that are in use. - View Dependent Claims (14, 15, 16)

17. An apparatus of detecting and identifying spectrum opportunities comprising:
-
at least one base station having at least a microprocessor, a transmitter, and a receiver; and at least one node in communication with the at least one base station having at least a sensing device, a transmitter, and a receiver, wherein the transmitter of the at least one base station transmits a list of at least one channel that is received by the receiver of the at least one node, and the sensing device of the at least one node senses each of the at least one channel in order to determine soft information of the channel and the transmitter of the at least one node transmits the soft information which is received by the receiver of the at least one base station and processed by the microprocessor of the at least one base station. - View Dependent Claims (18, 19, 20)
