Abstract (in Japanese) (See Japanese page) 
(in English) In the 5th generation mobile communication (5G), which is now in service in many countries around the world, higher speeds will be achieved by introducing beamforming and millimeter wave bands. On the other hand, since the millimeter-wave band has a narrow transmission range, it is necessary to develop an efficient service area using relay stations. Therefore, it is necessary to design an area based on a detailed understanding of the propagation environment of millimeter wave.
Since the millimeter-wave band has inherently short coverage and beamforming is applied to compensate for the short communication distance, it is necessary to create an area map that accurately maps location information and signal strength.
In this paper, we propose an area design that can reproduce the propagation environment in real time using digital twin and dynamically determine the deployment of the repeaters. As an initial study, we carried out high-precision propagation measurements in the 5G testbed field being constructed at the Ookayama campus and investigated the deployment of relay stations.
