    • The present invention provides a wireless communication system and a terminal. A base station notifies terminals of an intensity of a received interference power. The terminal controls a transmission power for transmitting data to the base station, which is one of base stations and to which data is to be transmitted, by referencing an intensity of interference power (OSI) notified from base stations to which data is not to be transmitted. The terminal calculates a decision value for increasing/decreasing the transmission power, wherein the decision value is variable according to the current transmission power of the terminal and propagation attenuations between the terminal and the base stations to which data is not to be transmitted, and variably controls the amount of transmission power increase/decrease according to the decision value for increasing/decreasing a transmission power.

    • A radio communication system for enabling control of a modulation scheme following variation in the propagation channel and control of a coding rate in a small amount of delay and arithmetic operation. In order to attain the object explained above, a transmitter station and a receiver station use in common the information of the maximum number of bits used for communication of each symbol. The transmitter station generates codeword by previously encoding the communication signal with the code having sufficient error correcting capability, assigns, to each symbol, the codeword to result in the maximum number of bits per symbol, and modulates and transmits the bits using the modulation scheme in which the number of bits per symbol is equal to or less than the maximum number of bits per symbol. Meanwhile, the receiver station demodulates, for each symbol, the bits with the modulation scheme, in which the number of bits per symbol is larger as the propagation channel quality is higher, among the modulation schemes in which the number of bits per symbol is less than the maximum number of bits per symbol and summarizes the demodulation results and executes the decoding process by adding the signal of zero likelihood to restore the shortage when the total sum of the number of bits per symbol in the modulation scheme used for the demodulation becomes equal to or larger than the predetermined value.
    • 一种无线电通信系统,用于在传播信道变化之后进行调制方式的控制,并且在少量的延迟和算术运算中控制编码率。 为了实现上述目的,发送站和接收站共同使用用于每个符号通信的最大位数的信息。 发射机站通过预先编码具有足够纠错能力的码的通信信号生成码字,向每个符号分配码字以产生每个码元的最大比特数,并使用调制方案调制和发送比特 每个符号的比特数等于或小于每个符号的最大比特数。 同时,对于每个符号,接收机站在每个符号的比特数较少的调制方案中,针对每个符号解调具有调制方案的比特,其中每个符号的比特数随传播信道质量越高越大 而不是每个符号的最大比特数,并且总结了解调结果,并且当用于解调的调制方案中的每个符号的比特数的总和变得相等时,通过添加零似然度的信号来恢复缺陷来执行解码处理 达到或大于预定值。
