Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, to actualize 6G, we investigated the path loss characteristics for 2-300 GHz bands in an urban microcell environment and compared those measurement results with ITU-R M.2412 path loss model for 5G system evaluation. The CI model's prediction results showed that RMSE was about 6.04 dB in the LOS environment. On the contrary, prediction results using the ABG model showed that RMSE was about 6.19 dB in the NLOS environment. It was found that the accuracy of regression results is improved than prediction results using M.2412 path loss model. The path loss coefficient is lower than that given by the M.2412 path loss model in the LOS environment, and the path loss coefficient and frequency dependency are more significant than that obtained by the M.2412 path-loss model.
