Abstract  Abstract

PROBLEM TO BE SOLVED: To improve error rate characteristics of a NACK.

SOLUTION: A scrambling part (214) multiplies a scrambling code 1 or -1 by a response signal which has been modulated and by multiplication of the scrambling code -1 makes a constellation invert for each of response signals on a cyclic shift axis. A spread part (215) performs primary spread of the response signal by using a ZAC sequence set by a control part (209). A spread part (218) performs secondary spread of the response signal which has been subjected to the primary spread by using a block-wise spreading code sequence set by the control part (209).
