摘要

Huawei and NTT DOCOMO announced what they claim is the world's first fifth-generation (5G), large-scale field trial in the 4.5-GHz band using new numerology and frame structure complying with the Third Generation Partnership Project (3GPP) 5G New Radio (NR) current agreements. In the trial, 11.29 Gb/s total user throughput and less than 0.5 ms one-way user plane latency were achieved in the macrocell coverage of a real urban application scenario in Yokohama, Japan. The macrocell was made up of one base station that worked in the 4.5-GHz band with 200-MHz bandwidth, 64 transceivers, and 23 pieces of user equipment (UE) of both static and mobile types. The trial combined multiuser (MU), multiple-input, multiple-output (MIMO) technology for simultaneous multiple access and a precoding algorithm that optimizes signals for maximized performance and also limits interuser interference. It achieved a MU-MIMO transmission of a maximum 79.82 b/s/Hz/cell.
