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.

1. A radio communication system including: a base station device that receives a random access preamble and transmits a random access response in response to the random access preamble,a mobile station device that transmits the random access preamble to the base station device, monitors both a Cell-Radio Network Temporary Identity (C-RNTI) and a Random Access-Radio Network Temporary Identity (RA-RNTI), and receives, upon detection of the C-RNTI and the RA-RNTI in a same sub-frame, both the random access response and the downlink data, wherein the RA-RNTI is carried by a first downlink control channel and identifies the random access response, and wherein the C-RNTI is carried by a second downlink control channel and notifies a resource assignment of downlink data. 2. A mobile station apparatus, comprising: a transmitter to transmit a random access preamble;a receiver to monitor both a Cell-Radio Network Temporary Identity (C-RNTI) and a Random Access-Radio Network Temporary Identity (RA-RNTI), and to receive, upon detection of the C-RNTI and the RA-RNTI in a same sub-frame, both a random access response transmitted by the base station device in response to the random access preamble and downlink data;wherein the RA-RNTI is carried by a first downlink control channel and identifies the random access response, the C-RNTI is carried by a second downlink control channel and notifies a resource assignment of downlink data. 3. A method comprising: transmitting, by a mobile station device, a random access preamble to a base station device;monitoring, by the mobile station device, both a Cell-Radio Network Temporary Identity (C-RNTI) and a Random Access-Radio Network Temporary Identity (RA-RNTI); andupon detection of the C-RNTI and the RA-RNTI in a same sub-frame, receiving, by the mobile station device, both a random access response transmitted by the base station device in response to the random access preamble and downlink data;wherein the RA-RNTI is carried by a first downlink control channel and identifies the random access response, the C-RNTI is carried by a second downlink control channel and notifies a resource assignment of downlink data. 4. The system according to claim 1, wherein the mobile station device is further configured to monitor the C-RNIT at an arbitrary timing. 5. The system according to claim 1, wherein the mobile station device is further configured to receive, upon detection of the RA-RNTI instead of the C-RNTI, the random access response. 6. The system according to claim 1, wherein the mobile station device is further configured to receive, upon detection of the C-RNTI instead of the RA-RNTI, the downlink data. 7. The mobile station device according to claim 2, wherein the mobile station device is further configured to monitor the C-RNIT at an arbitrary timing. 8. The mobile station device according to claim 2, wherein the mobile station device is further configured to receive, upon detection of the RA-RNTI instead of the C-RNTI, the random access response. 9. The mobile station device according to claim 2, wherein the mobile station device is further configured to receive, upon detection of the C-RNTI instead of the RA-RNTI, the downlink data. 10. The method according to claim 3, further comprising: monitoring, by the mobile station device, the C-RNIT at an arbitrary timing. 11. The method according to claim 3, further comprising: receiving, by the mobile station device, the random access response upon detection of the RA-RNTI instead of the C-RNTI. 12. The method according to claim 3, further comprising: receiving, by the mobile station device, the downlink data upon detection of the C-RNTI instead of the RA-RNTI.
