A mobile station device transmits a random access preamble to a base station device. The base station device receives the random access preamble from the mobile station device and transmits, to the mobile station device, a Random Access-Radio Network Temporary Identity (RA-RNTI) which notifies a resource assignment of a random access response. The mobile station device further monitors downlink control channels while detecting both a Cell-Radio Network Temporary Identity (C-RNTI) and the RA-RNTI, in which a downlink control channel includes the RA-RNTI and a downlink control channel includes the C-RNTI which notifies a resource assignment of downlink data. Upon detection of the C-RNTI and the RA-RNTI in a same sub-frame, the mobile station receives both the random access response and the downlink data, or receives either the random access response or the downlink data.

The device according to claim 7, wherein the processor is further configured to monitor the C-RNIT at an arbitrary timing. 9. The device according to claim 7, wherein the transceiver is further configured to receive, upon detection of the RA-RNTI instead of the C-RNTI, the random access response. 10. The device according to claim 7, wherein the transceiver is further configured to transmit, upon detection of the C-RNTI instead of the RA-RNTI, the uplink data. 11. The device according to claim 7, wherein the resource assignment of the uplink data is uplink grant of the uplink data. 12. The mobile station device according to claim 7, wherein the RA-RNTI and the C-RNTI are indicated by a downlink control channel. 13. An apparatus, comprising: a circuit configured to transmits a random access preamble;a circuit configured to monitors both a Cell-Radio Network Temporary Identity (C-RNTI) and a Random Access Radio Network Temporary Identity (RA-RNTI), anda circuit configured to, upon detection of the C-RNTI and the RA-RNTI in a same sub-frame after determining that the random access preamble was transmitted in an uplink synchronous status, receives the random access response according to the RA-RNTI which identifies a random access response, and transmit uplink data according to the C-RNTI which notified a resource assignment of the uplink data. 14. The apparatus according to claim 13, further comprising a circuit configured to monitors the C-RNIT at an arbitrary timing. 15. The apparatus according to claim 13, further comprising a circuit configured to receives, upon detection of the RA-RNTI instead of the C-RNTI, the random access response. 16.
