Incumbent spectrum hold device

1. A monitoring device comprising

a transceiver to receive a radio signal; and

a processor communicatively coupled to the transceiver to

monitor for and detect an interference on a primary spectrum of the radio signal, wherein the interference is caused by a cognitive radio (CR) in a vicinity of the monitoring device, and

report the interference as an infringement to a database, the processor of the monitoring device by way of the transceiver logging the interference to a policy database accessible to a CR base station that manages cognitive devices in the vicinity thereby notifying the CR base station of the infringement, the CR base station managing the cognitive devices in the vicinity by establishing and adjusting contours for CR allowed regions and contours for CR not allowed regions based access policies and the logged interference; and

continue monitoring and updating the database periodically with new detected interference information such that the contours for CR allowed regions and contours for CR not allowed regions are readjusted for cognitive devices in the vicinity.

2. The monitoring device of claim 1 , wherein the processor by way of the transceiver emits a beacon signal to report that an infringement has been detected on a frequency of the primary spectrum.

3. The monitoring device of claim 1 , wherein the processor identifies a cognitive radio signature signal of a cognitive radio and addresses a beacon signal to that cognitive radio, the beaconing signal causing the cognitive radio to modify spectrum levels in accordance with a specific pattern characteristic.

4. The monitoring device of claim 1 , wherein at least one cognitive device accesses a policy database to determine if the at least one cognitive device is transmitting on a frequency in the vicinity and causing the interference.

5. The monitoring device of claim 1 , wherein the processor by way of the transceiver notifies an incumbent device holding the primary spectrum that a cognitive device in the vicinity is producing the interference on the primary spectrum.

6. The monitoring device of claim 1 , wherein the processor scans a list of channels in the vicinity, measures the interference in the channels, and reports the interference to the database if the interference exceeds a threshold.

7. The monitoring device of claim 1 , wherein the processor reports to the CR base station at least one communication channel experiencing interference.

8. The monitoring device of claim 1 , wherein the processor reports to frequencies used in the vicinity, a duration and time of the interference on the frequencies, and interference levels on the frequencies.

9. The monitoring device of claim 1 , further comprising a Global Positioning System (GPS) to identify a location of the monitoring device, wherein the processor by way of the transceiver

transmits the location to the CR base station, and

reports contour information related to the location.

10. A cognitive radio (CR) base station managing a plurality of cognitive devices, the CR base station comprising:

a transceiver; and

a processor communicatively coupled to the transceiver to

receive an infringement from a CR monitoring device;

evaluate a transmit operation of the plurality of cognitive devices in view of the infringement based on access policies retrieved from a database;

update the access policies to manage operation of the plurality of cognitive devices to mitigate the infringement; and

repeating the evaluation and updates to manage the operation of the

plurality of cognitive devices so as avoid interference with incumbents; and wherein the CR base station managing the plurality of cognitive devices forms a first cognitive system which monitors another cognitive system for infringements to avoid interference with incumbents.

11. The CR base station of claim 10 , wherein the processor retrieves the infringement in response to the CR monitoring device logging the interference to the policy database.

12. The CR base station of claim 10 , wherein the processor receives the infringement by way of a beacon signal transmitted by the CR monitoring device identifying the interference.

13. The CR base station of claim 10 , wherein the infringement identifies at least one among a channel or frequency on which an interference was detected, a change in power spectrum levels, historical power spectrum levels, interference patterns, a time the interference was detected, a duration of the interference, and a location of the CR monitoring device.

14. The CR base station of claim 13 , wherein the processor receives the infringement by way of a beacon signal transmitted by the CR monitoring device identifying the interference.

15. The CR base station of claim 10 , wherein the processor recalculates a transmit power based on the infringement and updates the access policies to prevent transmission on the channel identified in the infringement.

16. A Cognitive Radio (CR), comprising:

a processor;

a transmitter;

a receiver; and

the processor and transmitter establishing a transmit operation based on access policies retrieved from a database, and that responsive to receiving an infringement from a CR monitoring device the processor adjusts the operation to mitigate the infringement caused by the transmit operation, the adjustment in operation allowing the infringing device to become non-infringing device by establishing and adjusting contours for CR allowed regions and contours for CR not allowed regions based the access policies and the received infringement.
