Abstract

A wireless communication apparatus by which deterioration of the separation characteristic of a code-multiplexed response signal can be suppressed to the minimum. In the apparatus, a control unit (209) controls a cyclic shift value of a ZC sequence used for the primary spreading by a spreading unit (214) and a Walsh sequence used for the secondary spreading by a spreading unit (217) according to a PUCCH number inputted from a judgment unit (208), the spreading unit (214) performs the primary spreading of the response signal with the ZC sequence set by the control unit (209), the spreading unit (217) performs the secondary spreading of the response signal with the Walsh sequence set by the control unit (209). The spreading unit (217) performs the secondary spreading of the response signal by using any of the Walsh sequences whose sequence length is shorter than the ZC sequence length among the Walsh sequences used in different mobile stations and which have the same cyclic shift value and are orthogonal to each other.
