摘要： Provided is a relay transmission method capable of obtaining the diversity effect even when a relay station has detected an error in a relay signal when performing communication between a base station and a mobile station via a relay station. In the relay station used in this method, a decoding unit (104) performs error-correction-decoding of a systematic bit by performing repeated decoding such as a turbo decoding by using a parity bit and obtains a decoding result formed by a systematic bit after the error-correction-decoding. An error judging unit (105) judges whether the decoded result has an error by using CRC (Cyclic Redundancy Check). An encoding unit (106) performs error-correction-encoding of the decoded result and obtains a systematic bit after error-corrected-encoded and a parity bit. A selection unit (107) selects the decoded result inputted from the decoding unit (104) or the bit string inputted from the encoding unit (106) according to the judgment result obtained by the error judging unit (105) and outputs it to a modulation unit (108).

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.
摘要翻译：一种能够防止吞吐量降低的无线通信方法。根据该无线通信方法，在帧（2）中，由于中继信号的调制方式为16QAM，所以中继站（1）判定延迟量为Deltat2，而另一中继站（2）判定为延迟量为Deltat4，因为中继信号的调制方案是QPSK。中继站（1）在帧（2）的Deltat2处将调制方案为16QAM的中继信号发送到中继站。另一方面，中继站（2）通过Deltat4检测中继站（1）在Deltat2发送中继信号的事实，并从检测到的事实估计中继站使用的调制方案（ 1）是16 QAM。中继站（2）然后将其调制方案从最初建立的QPSK调制方案更新为与中继站（1）相同的16QAM调制方案，并通过使用16QAM对中继信号进行调制，然后将其发送到基站。

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 “2^n×3^m×5^l”, 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 “2^n×3^m×5^l”, 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： Interference between users in an MU-MIMO system is minimized by effective precoding, without increasing an overhead of control data. In a wireless communication system in which multiplex communication is possible between multiple UE1, UE2, and BS, a channel estimation and precoding selection unit 539 in BS estimates channels from the respective UE1, UE2 to the BS, determines a precoding matrix P from a projection matrix to make the two channel response matrices orthogonal or nearly orthogonal, and feeds back the precoding matrix P to UE2, and executes precoding on only UE2 of the two. A precoding unit 524 in the UE2 employs the precoding matrix P that has been notified to perform precoding of a data stream, and sends the precoded data stream to the BS.

摘要： Provided are a scheduling device and a scheduling method, in which the amount of signaling of frequency resource allocation information can be reduced while the system throughput is maintained. In a base station device (100), a scheduling unit (113) selects, as an allocation resource for a terminal to which resources are to be allocated, at most one cluster band in each of a plurality of allocatable ranges set within a system band and generates allocation resource information including information relating to the selected cluster, and an encoding unit (114), a modulation unit (115), and a transmission RF unit (116) which serve as a transmission means transmit the allocation resource information generated by the scheduling unit (113) to the terminal to which the resources are to be allocated. Among the plurality of allocatable ranges, a first allocatable range is the entire system band, while a second allocatable range is a low frequency-side band or a high frequency-side band when the system band is divided into halves.
