Abstract

Provided is a radio communication device which can make Acknowledgement (ACK) reception quality and Negative Acknowledgement (NACK) reception quality to be equal to each other. The device includes: a scrambling unit () which multiplies a response signal after modulated, by a scrambling code '1' or “e” so as to rotate a constellation for each of response signals on a cyclic shift axis; a spread unit () which performs a primary spread of the response signal by using a Zero Auto Correlation (ZAC) sequence set by a control unit (); and a spread unit () which performs a secondary spread of the response signal after subjected to the primary spread, by using a block-wise spread code sequence set by the control unit ().
