1. A radio transmission apparatus comprising: an uplink scheduler which, in operation, determines an uplink transmission format and selects an index corresponding to the determined uplink transmission format, the uplink transmission format including a transport block size (TB size) for user data; a transmitter which, in operation, transmits the index to a mobile station; and a receiver which, in operation, receives the user data and control information, which are coded using the uplink transmission format and which are transmitted together from the mobile station, the control information being one or both of an acknowledgement/negative-acknowledgement (ACK/NACK) and a channel quality indicator (CQI), wherein a code rate of the user data for the TB size of the uplink transmission format indicated by the index is adjusted depending on whether the user data is transmitted from the mobile station together with the CQI, with the ACK/NACK, or with both of the CQI and ACK/NACK as the control information.
