Title
5g Downlink Throughput Performance Of 28 Ghz Band Experimental Trial At 300 Km/H
Abstract
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 high mobility trials at a velocity of 150 km/h using 28 GHz-band 5G prototypes implementing beam tracking To support ultra-high mobility on a bullet train, in April 2018, we conducted outdoor trials using the specially customized vehicle with the velocity of up to 300 km/h. This paper reveals the latest downlink performance results of the trial.
