    摘要： A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.

    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.

    摘要： Provided is a wireless communication apparatus by which the maximum throughput can be obtained while satisfying required reception qualities in multicarrier communication.

Namely, while the coding rate is same in all of the resource blocks, modulation system and the number of repetitions differ by resource block.

    摘要： A wireless communication method for improving the transmission efficiency in an upstream communication in OFDMA-TDD system or the like. An upstream transmission timing control part (108), which employs this method, controls, based on the OFDMA-TDD scheme, the transmission timings of a mobile station (#p) and a mobile station (#M) communicating with a base station (100). The upstream transmission timing control part (108) acquires information about the propagation delay times τp and τM of the mobile station (#p) and mobile station (#M). When the propagation delay time τp is shorter than the propagation delay time τM, the upstream transmission timing control part (108) decides the transmission timings of the mobile station (#p) and mobile station (#M) such that the timing at which the base station (100) starts receiving symbols from the mobile station (#p) in an upstream section is earlier, by αp times an OFDM symbol length (L) (where αp is a natural number), than the timing at which the base station (100) starts receiving symbols from the mobile station (#M) in the same section.
