摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2̂n×3̂m×5̂l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2̂n×3̂m×5̂l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number

摘要： A wireless communication method capable of preventing reduction of the throughput. According to this wireless communication method, in a frame (2), a relay station (1) decides that the amount of delay to be Δt2 because the modulation scheme of a relayed signal is 16 QAM, while another relay station (2) decides that the delay amount be Δt4 because the modulation scheme of a relayed signal is QPSK. The relay station (1) transmits, at Δt2 of the frame (2), the relayed signal, the modulation scheme of which is 16 QAM, to abase station. On the other hand, the relay station (2) detects, by Δt4, the fact that the relay station (1) transmitted the relayed signal at Δt2, and estimates, from the detected fact, that the modulation scheme used by the relay station (1) was 16 QAM. The relay station (2) then updates its modulation scheme from the initially established modulation scheme of QPSK to the same modulation scheme of 16 QAM as the relay station (1), and modulates the relayed signal by use of 16 QAM and then transmits it to the base station.

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 relay transmission method for communication between a base station and a mobile station via a relay station while producing a diversity effect even if the relay station detects an error in the relay signal. A decoding section (104) of the relay station used in this method performs error-correction decoding of a systematic bit by using a parity bit by repetition decoding such as turbo decoding and acquires the results of the decoding composed of the systematic bit having undergone the error-correction decoding. An error judging section (105) judges whether or not any error is present in the decoding results. Coding section (106) performs error-correction coding of the decoding results and acquires the error-correction coded systematic bit and parity bit. A selecting section (107) selects either the decoding results inputted from the decoding section (104) or a bit sequence inputted from the coding section (106) according to the result of the judgment by the error judging section (105) and outputs the selected one to a modulating section (108). A transmission control section (112) controls the operation of a radio transmitting section (109) according to the SNR of the received data symbol and the result of the judgment by the error judging section (105).

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.
