摘要： A wireless communication apparatus enabling improved system throughput while limiting the amount of signaling for feedback information. In this apparatus, a setting unit (101) sets transmission power differently for each of a plurality of sub-packets obtained by dividing transmission data (transmission packet). Here, the setting unit (101) sets transmission power differently for each of the plurality of sub-packets so that the total transmission power for the plurality of sub-packets becomes the same as the transmission power that is allocated in advance to the transmission packet that constitutes the plurality of sub-packets. A dividing unit (102) divides the transmission data (transmission packet) into a plurality of sub-packets. Then, a transmitting wireless communication apparatus (100) transmits the plurality of sub-packets in order of sub-packets of higher transmission power (lower error rate).

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： 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.
