Mobile station, base station, and communication control method

A base station which configures a plurality of component carriers to communicate with a mobile station, comprising:

• a reception unit configured to receive from the mobile 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 transmission unit configured to transmit whether to allow the non-gap measurement to the mobile 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.

A communication control method in a mobile station which configures a plurality of component carriers to communicate with a base station, comprising the steps of:

• transmitting 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;
• receiving whether to allow the non-gap measurement from the base station;
• and
• controlling 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.
