INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit capable of avoiding control information from being encoded at an undesired encoding ratio and prevent the transmission efficiency of control information from being degraded.SOLUTION: An encoding ratio setting section 122 sets the encoding ratio R'of a piece of control information which is time-multiplexed with a user data using a formula (1) by using: encoding ratio Rof the user data; PUSCH offset &Dgr;PUSCHoffset for respective control information; and a rank offset &Dgr;RANKoffset according to the number of ranks of data CH.
