Radio communication system, base station, mobile station, control method of base station, control method of mobile station, and storage medium storing program

A base station comprising:

• radio communication unit capable of performing radio communication with a mobile station by using first and second carrier frequency bands simultaneously for at least one of an uplink direction and a downlink direction;
• and
• control unit capable of switching whether or not to perform control relating to the second carrier frequency band by using a radio channel transmitted on the second carrier frequency band.

A mobile station comprising:

• radio communication unit capable of performing radio communication with a base station by using first and second carrier frequency bands simultaneously for at least one of an uplink direction and a downlink direction;
• and
• control unit capable of switching whether or not to perform control relating to the second carrier frequency band by using a radio channel transmitted on the second carrier frequency band.
