Abstract (in Japanese) (See Japanese page) 
(in English) To suppress inter-cell interference in a multi-cell configuration, a "network coordinated interference canceller" has been proposed, in which each base station cooperates to suppress inter-cell interference. The interference canceller utilizes the propagation channel responses from neighboring cell terminals to perform interference cancellation. Therefore, we proposed a method to estimate the propagation channel responses of neighboring cell terminals using the SRS (Sounding Reference Signal) defined in 5G NR. In actual cell configurations, there are position estimation errors at the base station, which can lead to inaccurate estimation of the propagation channel response. In this paper, we propose a method to adjust the demodulation timing considering these errors and determine the optimal correction values for accurately estimating the propagation channel response.
