Abstract: To actualize a new system capable of properly controlling the power of an interference signal in a case in which a radio signal interferes between frequency channels which are a combination of frequency channels that can partly overlap. [Solution] There is provided a communication control device equipped with: an inform ation acquisition unit for acquiring channel arrangement information about a first frequency channel and a second frequency channel which are a combination of frequency channels that can partly overlap an interference signal being transmitted on the first frequency channel and a desired signal subject to interference from the interference signal being transmitted on the second frequency channel; and an interference control unit for determining the overlapping on a frequency axis between the first frequency channel and the second frequency channel on the basis of the channel arrangement information and calculating according to the determined overlapping a protection ratio for protecting the second frequency channel from the interference.
