Communication control apparatus and communication control method

A communication control apparatus, comprising:

• an acquisition unit that acquires information on a plurality of second wireless systems that perform wireless communication by utilizing a radio wave of a frequency band used by a first wireless system;
• a first determination unit that determines, based on the information on the plurality of second wireless systems, an operation parameter regarding radio transmission of each of the plurality of second wireless systems so as to satisfy a protection standard regarding interference of the radio wave of the first wireless system;
• a calculation unit that calculates a residual interference quantity that is allowed to be additionally allocated to the plurality of second wireless systems based on the operation parameter determined by the first determination unit and the protection standard of the first wireless system;
• a classification unit that classifies the plurality of second wireless systems into a single or a plurality of sets;
• and
• a second determination unit that determines, based on information on the residual interference quantity, an adjustment quantity of the operation parameter of the plurality of second wireless systems belonging to a prescribed set out of the single or the plurality of sets.
