| Abstract(in English) | Field trials of the fifth-generation (5G) mobile communication system using 28GHz 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 highly-mobile outdoor trials up to velocity of 150 km/h using 28GHz-band 5G prototypes implementing beam tracking. To support ultra-high mobility on Shinkansen, we conducted outdoor trials using a vehicle with the velocity of up to 300 km/h. This report reveals downlink performance results of the ultra-highly mobile outdoor trials. |
