摘要： When MBMS communication is performed, a radio resource is efficiently used. A mobile communication method according to the present invention includes a step of notifying, by a radio base station eNB, the configuration of an MBSFN subframe through SIB2, and a step of receiving, by a mobile station UE, a PDSCH signal, which is transmitted in the MBSFN subframe through unicast communication, based on a PDCCH signal generated using C-RNTI of the mobile station UE when a PDCCH signal generated using MBSFN_Off-RNTI and a PDCCH signal generated using the C-RNTI of the mobile station UE have been received in a predetermined OFDM symbol in the MBSFN subframe.

摘要： PROBLEM TO BE SOLVED: To reduce battery consumption for mobile stations and efficiency using a radio resource when calling the mobile stations belonging to a plurality of groups at the same timing. SOLUTION: The mobile station sets a common data channel and a signaling control channel between the mobile station and a radio access network device and establishes communications. The mobile station has a call-signal identifier detecting means (108) detecting the identifier for a call signal from the signaling control channel at an intermittent receiving timing and a mobile-station group identifier detecting means (110) detecting the identifier for a mobile-station group, to which its own station belongs, from a part of the signaling control channel when detecting the call-signal identifier. The mobile station further has a radio-resource allocation-information detecting means (112) detecting a radio-resource allocation information for the call signal transmitted as a part of the signaling control channel when detecting a mobile-station group identifier, to which its own station belongs, in the mobile-station group identifier detecting means and a call-signal receiving means (114) receiving the radio resource indicated by the radio-resource allocation information.

摘要： A transmitter (10) includes a MAC-PDU generation unit (12) which multiplexes a MAC-PDU multiplexes MAC-SDU received from an RLC layer and supplies a MAC header containing the fixed length "LI" indicating the size of the MAC-SDU so as to generate a MAC-PDU in a MAC layer; and a MAC-PDU transmission unit (13) which transmits the generated MAC-PDU. The "LI" includes a part which defines the basic unit constituting the MAC-SDU and a part which defines the MAC-SDU size as a multiple of the basic units.
