摘要： There are provided a communication device, a base station, a communication system, and a communication method that make it possible to yield a diversity effect by cooperative relay without involvement of disproportionateness in data received by an eNB even when one of parties has unsuccessfully exchanged data. After received an ACK signal from a repeater 1, a repeater 2 which has transmitted a NACK signal in procedure 7 transmits data S2 to the eNB by use of its own resource, thereby making its own resource available for the repeater 1 (the repeater 2 does not use its own resource, and the repeater 1 uses the resource of the repeater 2). In procedures 8, the repeater 1 has received the NACK signal from the repeater 2 and subsequently transmits data S1 to the eNB by use of its own resource. Subsequently, the repeater 1 which has received the MACK signal in procedure 9 determines that the resource of the repeater 2 is available and transmits data P1 to the eNB by use of the resource of the repeater 2. In procedure 10, the repeater 1 transmits previously-generated data P2 to the eNB by use of its own resource.

摘要： A wireless communication apparatus and an error detection result feedback method wherein unnecessary retransmissions are avoided to improve the system throughput. At a base station (200), a decoding unit (205) decodes code words, which have been mapped to a TTI bundle, for the respective TTIs in the TTI bundle. An error detecting unit (206) detects errors in the decoding results. A control information generating unit (209) sequentially transmits, in accordance with detection timings, error detection result information related to the code word transmitted in the tail TTI in the TTI bundle, as well as error detection result information related to the code word transmitted in at least one of the other TTIs. In this way, an apparatus that transmits the code words can use the result of error detection in the tail TTI as a reference used for deciding the execution of a retransmission, so that unnecessary retransmissions can be avoided.

摘要： Disclosed is a wireless communication device that, when both localized transmission and distributed transmission are used, can obtain channel estimation accuracy equivalent to that of localized transmission with distributed transmission. With this device, a setting unit (108) sets the power density of a reference signal by setting the arrangement density in the time domain of the reference signal according to the continuity in the frequency domain of the reference signal. In addition, the setting unit (108) increases the arrangement density in the time domain of the reference signal as the continuity decreases. A transmission RF unit (111) transmits a reference signal having the power density that has been set by the setting unit (108).
