A mobile station which configures a plurality of component carriers to communicate with a base station includes a transmission unit configured to transmit to the base station a terminal capability associated with non-gap measurement indicating whether the mobile station is capable of performing inter-frequency measurement using a radio frequency (RF) chain which is not used for a component carrier; a reception unit configured to receive whether to allow the non-gap measurement from the base station; and a communication control unit configured to control communication according to a gap pattern of using a portion of an inter-frequency measurement duration for data communication, when the non-gap measurement is allowed.
