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： Provided is a radio communication device which can obtain an error ratio characteristic equivalent to the one obtained by using a tail bit, without using a tail bit in the error correction and encoding. The device includes: a blocking unit (106) which adds a bit indicating an error detection result in a CRC unit (105) to control data (a bit string) so as to constitute an encoded block and outputs the encoded block to an encoding unit (107); and the encoding unit (107) which corrects and encodes the encoded block. The blocking unit (106) forms an encoded block by a bit string of control data and a probability deviation existence bit added to the tail of the bit string.

摘要： The error rate characteristic in a wireless communication apparatus for relaying communications between a mobile station and a base station is improved. For the modulation level of the resource for network coding, the modulation level from a relay station to the mobile station or the modulation level from the relay station to the base station, whichever is lower, is selected and thus the modulation level becomes QPSK. The relay station preferentially assigns S1 of a systematic bit of high importance, of S1+P1 to the network coding resource. The signal of S1+P1 not assigned to the network coding resource is assigned to the resource for the base station from the relay station. In the example, S1 is assigned to the resource for network coding and P1 is assigned to the resource for the base station from the relay station.

摘要： There are provided a wireless communication apparatus, a wireless communication method, and a wireless communication system capable of selectively utilizing the advantages of both centralized control and distributed control while a time needed for cell searching is suppressed. FIG. 4(a) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are frequency-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a distributed control resource. FIG. 4(b) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are time-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a centralized control resource. Since a relay station transmits the P-SCH as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.

摘要： A wireless communication apparatus, method, and system selectively utilize advantages of both centralized control and distributed control while suppressing cell searching time.
