A relay station and a wireless communication system wherein novel retransmission control is achieved in cases when a TTI-bundling technique and a relay technique are used in communication between a terminal and a base station. A relay station (300) relays wireless communication between a terminal that transmits a wireless signal in which code words obtained by encoding a single set of transmission data have been mapped to a TTI bundle consisting of a plurality of TTIs, and a base station that receives the wireless signal and transmits error detection information related to the code word transmitted in the tail TTI of the TTI bundle. At the relay station (300), a control information generating unit (309) transmits error detection information related to the code word transmitted in the front TTI of the TTI bundle.
