    • A wireless base station apparatus communicates with first terminal devices belonging to the present cell by means of IDMA. The apparatus receives signals sent from the first terminal devices and at least a signal sent from a second terminal device belonging to another cell; separately extracts each received signal from the first terminal devices and the second terminal device from the signals received by the receiver and computes a channel value for each received signal, by using interference replica signals; sends information for requesting a second wireless base station apparatus which communicates with the second terminal device to send a log-likelihood ratio obtained based on a signal received from the second terminal device; performs decoding using the channel value for each first terminal device, and generates a log-likelihood ratio as a decoding result and the corresponding interference replica signal; and performs decoding using the log-likelihood ratio received from said second wireless base station apparatus and the channel value for the second terminal device, and generates a log-likelihood ratio as a decoding result and the corresponding relevant interference replica signal.
    • 无线基站装置通过IDMA与属于本小区的第一终端装置进行通信。 该装置接收从第一终端装置发送的信号和至少从属于另一小区的第二终端装置发送的信号; 分别从接收机接收的信号中提取出来自第一终端设备和第二终端设备的每个接收信号,并通过使用干扰复制信号来计算每个接收信号的信道值; 发送用于请求与第二终端装置通信的第二无线基站装置的信息,发送基于从第二终端装置接收的信号获得的对数似然比; 使用每个第一终端设备的信道值执行解码,并且生成对数似然比作为解码结果和相应的干扰复制信号; 并使用从所述第二无线基站装置接收的对数似然比和第二终端装置的信道值进行解码,并生成对数似然比作为解码结果和对应的相关干扰复制信号。
