1. A communication control device, comprising:
an interference ratio calculating unit configured to calculate an adjacent channel interference ratio between a first radio system, which is a protection target, and a second radio system, which is an interference source, wherein the adjacent channel interference ratio is calculated in a case where the second radio system shares and uses a part or an entire frequency band used by the first radio system;
a guard band calculating unit configured to calculate a guard band, necessary for a channel of the first radio system and the second radio system, based on the adjacent channel interference ratio;
a notifying unit configured to notify the first radio system and the second radio system of guard band information corresponding to a first calculation result of the guard band calculating unit, wherein
the second radio system sets a reduced transmission bandwidth configuration based on the notified guard band information, and
a specific terminal device of the second radio system is with a reduced resource blocks based on the set reduced transmission bandwidth configuration; and
the notifying unit is further configured to notify to the second radio system a number of the reduced resource blocks that are reduced in the specific terminal device as the guard band information.
