Sony patents method for sharing radio frequencies between systems
Sony has been granted a patent for a communication control device that manages how different radio systems share frequency bands. The system processes requests from a secondary system to use parts of a primary system's frequency, separating the request into basic and extended zones. It then sends a single message back containing decisions for both the basic and extended usage.
In the filing’s own words
A communication control device includes: an acquisition unit configured to acquire a request to allow a communication device configuring a second radio system to secondarily use at least a part of a frequency band used by a first radio system, the request including information on at least one basic zone related to a basic operation of the communication device and information on at least one extension zone obtained by extending the basic zone; a first determination unit configured to perform a first determination related to the information on the basic zone; a second determination unit configured to perform a second determination related to the information on the extension zone; and a notification unit configured to notify the second radio system of a first response corresponding to the first determination and a second response corresponding to the second determination by enclosing the first response and the second response in one message.
What exactly they claim (claim 1)
1. A communication control device, comprising: an acquisition unit configured to acquire a request to allow a communication device configuring a second radio system to secondarily use at least a part of a frequency band used by a first radio system, the request including information on at least one basic zone related to a basic operation of the communication device and information on at least one extension zone obtained by extending the at least one basic zone; a first determination unit configured to perform a first determination related to the information on the at least one basic zone; a second determination unit configured to perform a second determination related to the information on the at least one extension zone; and a notification unit configured to notify the second radio system of a first response corresponding to the first determination and a second response corresponding to the second determination by enclosing the first response and the second response in one message.
