摘要： A communication relay apparatus wherein the error rate characteristic of a relay destination is improved to raise the throughput, while reducing the given interference power to prevent the reduction of the throughput of the whole communication system. In the apparatus, a signal addressed to a base station is received (ST1010), and a decoding process and other processes are performed (ST1020). A bit error determination is performed (ST1030), and if there is no bit error, a reproduction/relay process (ST1050) is performed. If there is any bit error, a threshold-based determination of reception quality is performed for each of subcarriers (ST1120-1130). If the reception quality is greater than a threshold value, the corresponding subcarrier is outputted (ST1140); otherwise, the corresponding subcarrier is not relayed (ST1150). A signal, which has been subjected to either process, is transmitted (ST1060).

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 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).

摘要： Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.
