5G Worldwide Dev
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.
