Abstract
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.
