Communication control apparatus and wireless communication apparatus
First Claim
1. A communication control apparatus comprising:
- circuitry configured to;
calculate and allocate a transmit power, 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;
determine a variation in a number of secondary systems;
adjust the margin for interference avoidance when the variation in the number of secondary systems is greater than a threshold value; and
signal the adjustment of the margin for interference avoidance to the 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.
