Abstract (in Japanese) (See Japanese page) 
(in English) Cell-Free massive MIMO (CF-mMIMO) is gaining attention as a technology that can ensure wireless quality without depending on location by eliminating the concept of cell coverage in cellular systems. For the wide deployment of radio access networks (RAN) using CF-mMIMO, phase synchronization of radio signal among distributed access points (APs) is a challenge. In this paper, we report the evaluation results of a method to improve the wireless quality of downlink CF-mMIMO by predicting the variation in phase differences between APs.
