Title
28 GHz-Band Experimental Trial Using the Shinkansen in Ultra High-Mobility Environment for 5G Evolution
Abstract
In order to enhance the fifth generation (5G) mobile communication system further toward 5G Evolution, high bit-rate transmission using high SHF bands (28 GHz or EHF bands) should be more stable even in high-mobility environments such as high speed trains. Of particular importance, dynamic changes in the beam direction and the larger Doppler frequency shift can degrade transmission performances in such high frequency bands. Thus, we conduct the world's first 28 GHz-band 5G experimental trial on an actual Shinkansen running at a speed of 283 km/h in Japan. This paper introduces the 28 GHz-band experimental system used in the 5G experimental trial using the Shinkansen, and then it presents the experimental configuration in which three base stations (BSs) are deployed along the Tokaido Shinkansen railway and a mobile station is located in the train. In addition, transmission performances measured in this ultra highmobility environment, show that a peak throughput of exceeding 1.0 Gbps and successful consecutive BS connection among the three BSs.
