In an MBMS service desired to be received, if a condition for performing an MBMS request (an MBMS request trigger criterion) is satisfied (S3: YES), a mobile station 20a in an idle mode (RRC_IDLE) enters an MBMS request transmission process, transmits a preamble to a base station 10b, receives a random access response including scheduling information for transmitting a Message 3 and the like from the base station 10b, and transmits the Message 3 including an RRC Connection Request (including an NAS ID of the mobile station itself), the MBMS request and channel quality information to the base station 10b (S4), and if an Message 4, which includes RRC Connection Setup that is destined for the mobile station itself and includes the NAS ID, and which includes feedback resource assignment information, is received from the base station 10b (S5: YES), the mobile station 20a transits to a connected mode (RRC_CONNECTED), and also uses the designated resource to provide feedback to the base station (S6). Thereby, the MBMS service can be efficiently provided via SCPTM transmission.
