1. A wireless communication system comprising:
- a first base station device;
a second base station device; and
a mobile station device configured to communicate with the first base station device using a first component carrier and to communicate with the second base station device using a second component carrier, whereinthe second base station device comprises;
carrier aggregation communication rejection determining circuitry that determines, based on a result of measurement of a communication environment, whether or not to disconnect the second component carrier; and
carrier aggregation communication rejection requesting circuitry that transmits, in a case that the carrier aggregation communication rejection determining circuitry determines to disconnect the second component carrier, to the first base station device, a carrier aggregation communication rejection request that requests the first base station device to reject carrier aggregation communication, andthe first base station device comprises;
disconnection preparation requesting circuitry that transmits, upon receiving the carrier aggregation communication rejection request, to the second base station device, a disconnection preparation request that requests the second base station device to prepare to disconnect the second component carrier.
