RADIO COMMUNICATION SYSTEM AND MOBILE STATION DEVICE
A mobile station device transmits a random access preamble to a base station device and performs uplink timing alignment based on the synchronization timing deviation information included in a random access response which the base station device transmits in response to the transmitted random access preamble, wherein in an uplink synchronous status, the mobile station device does not perform uplink timing alignment based on synchronization timing deviation information included in a random access response, which is a response to a random access preamble whose preamble ID is randomly selected by the mobile station device.
1 . A radio communication system including a mobile station device which transmits a random access preamble to a base station device and receives a random access response which the base station device transmits in response to the transmitted random access preamble, and the base station device which receives the random access preamble from the mobile station device and transmits a random access response in response to the received random access preamble,
wherein the mobile station device concurrently receives downlink data which the base station device transmits at an arbitrary timing and the random access response.
2 . A radio communication system including a mobile station device which transmits a random access preamble to a base station device and receives a random access response based on an RA-RNTI which the base station device transmits in response to the transmitted random access preamble, and the base station device which receives the random access preamble from the mobile station device and transmits, to the mobile station device, the RA-RNTI notifying a resource assignment of the random access response in response to the received random access preamble,
wherein the mobile station device monitors both a C-RNTI notifying a downlink resource assignment from the base station device at an arbitrary timing and the RA-RNTI, thus receiving both the random access response and downlink data or either the random access response or the downlink data.
3 . A mobile station device which transmits a random access preamble to a base station device and receives a random access response which the base station device transmits in response to the transmitted random access preamble, wherein the mobile station device concurrently receives downlink data which the base station device transmits at an arbitrary timing and the random access response.
4 . A mobile station device which transmits a random access preamble to a base station device and receives a random access response based on an RA-RNTI which the base station device transmits in response to the transmitted random access preamble, wherein the mobile station device monitors both a C-RNTI notifying a downlink resource assignment from the base station device at an arbitrary timing and the RA-RNTI, thus receiving both the random access response and downlink data or either the random access response or the downlink data.
5 . A radio communication system including a mobile station device which transmits a random access preamble to a base station device and transmits uplink data based on an uplink resource assignment notified by way of a random access response indicated by an RA-RNTI which the base station device transmits in response to the transmitted random access preamble, and the base station device which receives the random access preamble from the mobile station device and transmits, to the mobile station device, the RA-RNTI indicating the random access response notifying an uplink resource assignment in response to the received random access preamble,
wherein the mobile station device monitors both a C-RNTI notifying an uplink resource assignment from the base station device at an arbitrary timing and the RA-RNTI, thus transmitting uplink data.
