Disclosed is a technique for providing a mobile terminal and the like capable of reducing inter-cell interference between a macro cell and a small cell, suppressing frequent switching of a primary cell in carrier aggregation, and hence reducing an increase in the processing load on a base station and an increase in the power consumption of the terminal. According to the technique, there are included a receiving unit 603 for receiving a message including information for causing a reception quality in a second cell to be measured in tune with timing of a predetermined control channel area of a signal to be transmitted from a first base station in a predetermined frequency band, and a measurement unit 605 for measuring the reception quality in the second cell based on the information received.
