Abstract
Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unitdetermines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unitprovided in the transmission determining unitdetermines an MCS for the relay signal. A transmission instruction generated by the transmission determining unitis output to a bufferand an ACK/NACK generating unit. The determined MCS is output to an error correction coding unitand a modulation unit. The ACK/NACK generating unitgenerates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.
