Abstract (in Japanese) (See Japanese page) 
(in English) In 5G mobile communication system, it is one of the most important issues to clarify the propagation characteristics in the high-SHF (over 6 GHz) and EHF (mainly 30 – 60 GHz) bands. The accuracy of Ray Tracing (RT) has been evaluated by comparing with measurement in street cell environment for these frequency bands. This report focuses on the error observed in Non Line-Of-Site (NLOS). The shape of buildings is considered as a box with right-angle wedges in the conventional model. This report proposes alternative model with more realistic structure. The accuracies of conventional and proposed models are evaluated in order to improve the accuracy of RT simulation.
