1. radio communication device, comprising:

  • First spectrum-spreading unit, use by the ZC sequence of any one definition in multiple cyclic shift amount or multiple sequences that can be separated from each other by mutually different described multiple cyclic shift amounts, a spread spectrum is carried out to confirmed/non-confirmed number or channel quality index signal;

    Second spectrum-spreading unit, any one using in multiple orthogonal sequence carries out secondary spread spectrum to described confirmed/non-confirmed number that carries out a described spread spectrum;

    AndControl unit, control described first spectrum-spreading unit, the minimum value of the difference of the cyclic shift amount that the cyclic shift amount used to make described channel quality index signal and confirmation/non-acknowledgement signal afterwards use becomes more than the minimum value of the difference of the described confirmed/non-confirmed number cyclic shift amount used.
