摘要： 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 unit 16 determines 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 unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.

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： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.

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： 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.
