摘要 |
<p>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 Äp and ÄM of the mobile station (#p) and mobile station (#M). When the propagation delay time Äp is shorter than the propagation delay time ÄM, 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 ±p times an OFDM symbol length (L) (where ±p 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.</p> |
