Claim:
A mobile communication method, comprising: a step A in which a mobile station transmits an uplink data signal using a shared uplink resource designated by an uplink scheduling signal to a radio base station, upon reception of the uplink scheduling signal from the radio base station, the uplink scheduling signal including a CB-RNTI (Connection Based-Radio Network Temporary Identity) which is not a C-RNTI (Cell-Radio Network Temporary Identity) identifies an uplink scheduling signal designating a dedicated uplink resource usable by a dedicated mobile station; a step B in which the radio base station transmits a downlink control signal including the CB-RNTI on successful reception of the uplink data signal transmitted by the mobile station; and a step C in which the radio base station transmits a downlink data signal including the C-RNTI of the mobile station using a downlink resource designated by the downlink control signal.
