COMMUNICATION CONTROL DEVICE, COMMUNICATION CONTROL METHOD, AND COMMUNICATION CONTROL SYSTEM
First Claim
1. A communication control device comprising:
- a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system; and
a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit,wherein, upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed by the power distribution unit satisfy a predetermined condition with respect to a certain secondary system, the notification unit notifies the secondary system of a new value of the second transmission power.

Abstract
There is provided a communication control device including a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system, and a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit. Upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed by the power distribution unit satisfy a predetermined condition with respect to a certain secondary system, the notification unit notifies the secondary system of a new value of the second transmission power.

12. A communication control method comprising:
-
distributing, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system; and notifying each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit, wherein, upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed satisfy a predetermined condition with respect to a certain secondary system, the secondary system is notified of a new value of the second transmission power.

13. A communication control system comprising:
-
a communication control device including a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system, and a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit; and a communication device configured to set a transmission power for operating the secondary system within a range of the value of the second transmission power notified from the communication control device, wherein, upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified to the communication device and a value of the first transmission power which is newly distributed to the communication device satisfy a predetermined condition, the notification unit of the communication control device notifies the communication device of the new value of the second transmission power.
