[Problem] To appropriately control an accumulative interference from a plurality of secondary systems without excessively increasing signaling. [Solution] Provided is a communication control apparatus comprising: a power distributing unit that distributes, to one or more secondary systems, a transmission power that is allowable for the secondary use of a frequency channel protected for a primary system; and an informing unit that informs a value of a second transmission power determined in accordance with the value of the first transmission power distributed by the power distributing unit for each secondary system. When the transmission power is updated, the informing unit informs, to a secondary system, a new value of the second transmission power only if both the previously informed value of the second transmission power for that secondary system and a value of the first transmission power, which has been distributed anew by the power distributing unit, satisfy predetermined conditions. |
