The present invention aims to reduce an insertion loss or the like caused by a diplexer inserted to reduce leakage from an uplink bandwidth to a downlink bandwidth of different bands, and thereby to improve a communication quality. A mobile communication method according to the present invention includes the steps of: transmitting simultaneous transmission capability information from a mobile station UE to a radio base station eNB, the simultaneous transmission capability information indicating whether or not the mobile station UE is able to transmit uplink data signal via multiple carriers in multiple bands within a same sub-frame in performing uplink CA; performing scheduling for the mobile station UE by the radio base station eNB based on the simultaneous transmission capability information; and performing communications by the mobile station UE based on the scheduling information.
