Abstract  Abstract

Claims is capable of improve the error rate characteristic is NACK radio communication device which transmits request. In the device a scrambling unit (214) the scrambling code (1) or (-1) is connected with the a signal modulated by a scrambling code (-1) for multiplying the constellation rotation to each signal on a cyclic shift axis the diffusion unit (215) for responding with a ZAC sequence set by a control unit (209) for processing the first time spread spectrum frequency unit (218) is a signal of the first frequency by a control unit (209) of a spread spectrum code sequence for the second time.

Provided is a radio communication device which can improve the NACK error rate characteristic. The device includes: a scrambling unit (214) which multiplies a response signal after modulated by a scrambling code 1 or -1 so as to inverse a constellation for each of response signals on a cyclic shift axis; a spread unit (215) which performs a primary spread of the response signal by using a ZAC sequence set by a control unit (209); and a spread unit (218) 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 (209).
