Abstract: A parity bit generating section 110 generates parity bits of FEC for error correction from transmission data. A transmission power deciding section 111 decides transmission power at the time of retransmitting the parity bits from the number of information bits of transmission data and the number of parity bits. A transmission power controller 112 controls transmission power based on information decided by the transmission power deciding section 111 and outputs the resultant to a radio transmission section 104.

Abstract: A mobile communication system which is capable of, when carrying out mobile communication using a shared channel, increasing in efficiency of transmission timing of the data transmission rate request value to prevent wasteful power consumption and hence reduce power consumption. The mobile station apparatus 102 of the mobile communication system measures CIR of the received signal from the base station apparatus 101 at the CIR measuring section 306, and decides the data transmission rate request value corresponding to the measured CIR value at the rate request value deciding section 307. Also, it detects an error of the received signal at the CRC section 304, and, when no error is found, calculates a difference between the average data transmission rate from the base station apparatus 101 and the data transmission request value at the rate request value transmission controlling section 308. Then, it transmits the data transmission rate request value to the base station apparatus 101 only when the obtained difference is larger than a threshold value.

Abstract: 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.
