The communication device includes: 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 the number of retransmissions of the initial transmission signal and the retransmission signal which are included in the signal 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. An increase of delay can be prevented when retransmission is repeated.

摘要： A base station is capable of efficiently notifying a terminal of control information. The base station communicates with the terminal using a sub-frame including a plurality of resource block pairs. The base station sets a second control channel region in the terminal through RRC signaling that is higher-layer control information, the second control channel region being a region set differently from a first control channel region in which a first control channel is to be arranged. The base station transmits control information for the terminal by mapping the control information to a second control channel that is to be arranged in the second control channel region. The first control channel region is set in the sub-frame to be specific to the base station, and the second control channel region is set in the sub-frame to be specific to the terminal in units of the resource block pairs.
