    Abstract: In CA performed using three or more frequency bands, whether or not a mobile station UE is capable of performing an inter-frequency measurement without a gap is properly determined. The mobile station UE according to the invention includes a transmission unit 11 configured to transmit “UE Capability” indicating a capability of the mobile station UE to a radio base station eNB. The transmission unit 11 is configured to notify frequency bands in which the mobile station UE is capable of performing an inter-frequency measurement without a gap for each “CA band combination” as the “UE Capability”.

    Abstract: In a radio base station (eNB), a reception unit calculates “TAmacro” on the basis of a propagation delay (Tpd,macro) in a cell (#1), which is a temporal difference between a transmission timing of a first uplink signal at a mobile station (UE#1) and a reception timing of the first uplink signal at the radio base station (eNB). A transmission unit is configured to transmit, as “TApico”, a sum of the “TApico” and “DL/UL OFFSETpico” that is an offset value between a propagation delay (Tpd,pico) in a cell (#11) and the propagation delay (Tpd,macro) in the cell (#1). Here, the propagation delay (Tpd,pico) is a temporal difference between a transmission timing of a second uplink signal at a mobile station (UE#2) and a reception timing of the second uplink signal at the radio base station (eNB).
