In order to improve the use efficiency of radio resources upon executing a CA function, a base station (10A) forming a communication control system simultaneously transmits and receives a main carrier (100) and a plurality of sub-carriers (101 and 102) to wirelessly communicate with a mobile station (20). Prior to this, the base station (10A) notifies, to the mobile station (20) through the main carrier (100), first control information (201) for communication using the first sub-carrier (101), and first difference information (401) on a difference between the first control information (201) and second control information (202) for communication using another sub-carrier (102). The mobile station (20) reproduces the second control information (202) by using the first control information (201) and the first difference information (401).
