Abstract:
1. A radio transmission apparatus comprising: a receiving unit configured to receive an index indicating a transmission format including a transport block size (TB size) for user data; a coding unit configured to code the user data and control information using the transmission format, the control information being one or both of an acknowledgement/negative-acknowledgement (ACK/NACK) and a channel quality indicator (CQI); and a transmitting unit configured to transmit the coded user data together with the coded control information, wherein said coding unit adjusts a code rate of the user data for the TB size of the transmission format indicated by the received index such that a code rate of the user data transmitted together with the control information is different from a code rate of the user data transmitted without the control information, the user data code rate adjustment being dependent on whether the user data is transmitted together with the CQI, with the ACK/NACK, or with both of the CQI and ACK/NACK.
