Patent ID: 8381060

Claim:
A communication device which performs a hybrid automatic repeat request process of requesting a transmission source to perform retransmission when an error is detected from a received signal, the communication device comprising: a reception unit that receives a signal into which an initial transmission signal and a retransmission signal are multiplexed among signals including the initial transmission signal and the retransmission signal for any one signal; a detection order decision unit that decides an order of detection of the initial transmission signal and the retransmission signal from the signal received by the reception unit in response to information for determining the initial transmission signal or the retransmission signal from the initial transmission signal and the retransmission signal which are received by the reception unit; and a signal detection unit that removes an interference component from the signal received by the reception unit by using a signal detected by the communication device according to the order decided by the detection order decision unit, and that detects the initial transmission signal and the retransmission signal.
