<P>PROBLEM TO BE SOLVED: To provide a radio communication system that uses OCC for DMRS, in which a base station device can correctly receive PUSCH. <P>SOLUTION: If an uplink grant contains SPS C-RNTI allocated to an own device for instructing re-transmission, or, the uplink grant contains C-RNTI allocated to the own device, a mobile station device determines cyclic shift and OCC applied to DMRS based on the cyclic shift information of the uplink grant (step S204). If the SPS C-RNTI is contained and re-transmission is not instructed, or if the uplink grant contains T C-RNTI corresponding to the message of random access, the mobile station device determines only the cyclic shift that is applied to DMRS based on the cyclic shift information of the uplink grant (step S205). <P>COPYRIGHT: (C)2012,JPO&INPIT |
