Communication control apparatus and wireless communication apparatus
First Claim
1. A communication control apparatus comprising:
- circuitry configured to;
allocate a transmit power, including a margin for interference avoidance, for one or more secondary systems that secondarily use frequency channels allocated to a primary system;
determine a variation in a number of one or more secondary systems;
adjust the allocated transmit power when the variation in the number of one or more secondary systems is greater than a threshold value; and
signal information related to the allocated transmit power to the one or more secondary systems.

Abstract
[Object] To achieve both prevention of harmful interference and promptness of power allocation under conditions in which multiple secondary systems may be managed.
[Solution] Provided is a communication control apparatus including: a calculation unit configured to calculate a transmit power to be allocated, including a nominal transmit power and a margin for interference avoidance, for one or more secondary systems that secondarily use frequency channels protected for a primary system; and a determination unit configured to determine a variation in a number of secondary systems, and cause the calculation unit to adjust the margin for interference avoidance on a basis of the determined variation.

22. A communication control apparatus comprising:
-
circuitry configured to; communicate with a master device of one or more secondary systems that secondarily use frequency channels allocated to a primary system; and signal, based on information acquired from a data server that calculates a transmit power to be allocated for the one or more secondary systems including a margin for interference avoidance adjusted when a variation in a number of one or more secondary systems is greater than a threshold value, information related to transmit power allocation to the master device. - View Dependent Claims (23)

24. A wireless communication apparatus that operates and manages a secondary system that secondarily uses a frequency channel allocated to a primary system, the wireless communication apparatus comprising:
-
circuitry configured to; receive signaling of information related to an allocated transmit power from a data server that calculates the allocated transmit power for the secondary system including a margin for interference avoidance adjusted when a variation in a number of one or more secondary systems is greater than a threshold value; and control wireless communication between the wireless communication apparatus and one or more terminal apparatuses according to the allocated transmit power indicated by the information.

25. A communication control apparatus, which has an authority to allocate a transmit power to one or more secondary systems, comprising:
-
circuitry configured to; in a case in which other secondary systems are managed by another communication control apparatus, acquire information indicating a number of the other secondary systems that are managed by the another communication control apparatus having authority to allocate other transmit power and that should be considered in transmit power allocation from the communication control apparatus; allocate the transmit power, including a margin for interference avoidance, for the one or more secondary systems that secondarily use frequency channels allocated to a primary system; determine a variation in a number of one or more secondary systems; adjust the allocated transmit power when the variation in the number of one or more secondary systems is greater than a threshold value; and signal information related to the allocated transmit power to the one or more secondary systems.
