摘要： An objective is to enable a radio base station eNB to recognize a time point when a transition of an Scell to an active state is completed. A mobile station UE according to the invention includes a transmission unit 14 configured to, when an activation command for a deactive Scell is received, start reporting of CSI in the Scell to the radio base station eNB at predetermined timing before transition of an Scell to an active state is completed. The transmission unit 14 reports CSI to the radio base station eNB at predetermined intervals even during a time period from the time point when the CSI reporting is started to a time point when the transition of the Scell to the active state is completed.
