Abstract (in Japanese) (See Japanese page) 
(in English) Toward realization of 5th Generation Mobile Communications (5G), we have proposed 1-tap time-domain beamforming (TDBF) and digital assisted analog beamforming (DAABF) for wireless entrance links which can receive strong direct wave. Moreover, computer simulation results have already suggested that the beamforming technologies work properly and effectively. In this paper, we report about 75 GHz band outdoor and indoor propagation measurements. We performed the outdoor measurements at NTT Musashino R&D Center and the indoor measurements at NTT Yokosuka R&D Center on the assumption wireless entrance to street small cell. The result shows that received level of direct wave is higher than the one of reflection waves and that frequency spectrums become flat equally in spite of different element because the measurement environment is LOS and we use horn antenna. Furthermore, we revealed that we can approximate arrival direction of wave as plane and K-factor by received level fluctuation of 200 elements.
