Abstract (in Japanese) (See Japanese page) 
(in English) Field trials of the fifth-generation (5G) mobile communication system using 28 GHz band at which almost 1-GHz band will be available have been performed all over the world. To realize large coverage at such a high frequency band, beamforming by Massive MIMO (Multiple Input Multiple Output) is necessary to compensate large path loss. Furthermore, beam tracking which adaptively changes beam direction according to user location is an important function to support user mobility. Authors already conducted outdoor trials for downlink performance evaluation in highly-mobile outdoor environment up to velocity of 150 km/h using 28GHz-band 5G prototypes with a single base station implementing beam tracking. On the other hand, importance of evaluation of uplink transmission has been increasing for e.g. video streaming from high speed train. Handover performance is also important for a continuous video streaming. Thus, authors conducted outdoor trials for evaluation of uplink performance and that of handover performance in ultra-highly mobile environment. This report reveals results of uplink and handover performances in the ultra-highly mobile outdoor trials.
