Abstract
A monitoring device (141) can include a transceiver (202) to receive a radio signal, and a controller (203) communicatively coupled to the transceiver to detect an infringement on the radio signal and report the infringement to a database. One or more policies within the database can be updated to mitigate the infringement. The monitoring device can also detect whether a cognitive radio (111) is generating interference on a primary spectrum used by an incumbent device (151). Other embodiments are disclosed.
Claims16
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.
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.
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.
