摘要： A radio communication device in which the waste of physical resources involved in the repetition transmission of a response signal can be minimized with no restriction on the scheduling of a base station imposed or with the restriction on the scheduling thereof minimized. In this device, a control unit (209) selects the ZAC sequence of the cyclic shift amount corresponding to a PUCCH number inputted from a determination section (208) from among ZAC#0 to ZAC#11 to set it to a spreading section (215) and selects the block-wise spreading code sequence corresponding to the PUCCH number inputted from the determination section (208) from BW#0 to BW#2 to set it to a spreading section (218). More specifically, the control unit (209) selects any of the resources defined by the ZAC#0 to ZAC#11 and the BW#0 to BW#2. As a result, the more the number of transmissions of the response signal, the less the number of resources the control unit (209) can select.
