NTT Readies 6G Tech Trials
June 8, 2022
NTT DOCOMO and NTT
will collaborate with
world-leading mobile technology vendors Fujitsu, NEC, and Nokia to conduct
experimental trials of new mobile communications technologies for the targeted
commercial launch of 6G services by around 2030.
Launching the envisioned 6G services will require verification of numerous new
mobile technologies, including those needed to newly use frequencies in the
millimeter and sub-terahertz (above 6 GHz) bands, in addition to bands for
existing 5G services. The trials are also expected to verify AI-based wireless
transmission methods. DOCOMO and NTT will jointly conduct experimental trials
with the three vendors, focusing on mobile technologies using new 6G frequency
bands and AI-based wireless technology among these various mobile technologies.
The new 6G system will greatly exceed the performance of 5G and simultaneously
provide high-speed, large capacity, and low latency capabilities, use new
high-frequency bands such as sub-terahertz bands above 100 GHz, expand
communication coverage in the sky, at sea and in space, and enable both
ultra-low-power consumption and low-cost communications.
The realization of 6G is one of the most important goals envisaged in the NTT
group's Innovative Optical and Wireless Network (IOWN)* project for launching
all-new communication infrastructure. Aiming to realize "5G Evolution & 6G
powered by IOWN," DOCOMO and NTT are actively conducting 6G research and
development combining NTT's optical and wireless technologies with DOCOMO's
Naoki Tani, Executive Vice President and Chief Technology Officer at DOCOMO,
said: "6G studies are progressing two or three years ahead of that of 5G. From
this early stage, we would like to collaborate with world-leading global vendors
to proactively demonstrate breakthrough concepts and technologies and promote
them to the world."
DOCOMO and NTT will begin conducting indoor trials within the fiscal year ending
in March 2023, and outdoor trials will begin in the following fiscal year. The
trials are expected to verify concepts proposed so far by DOCOMO and NTT and
will be reported in global research groups, international conferences and
standardization activities related to 6G, and will serve as a foundation for
more advanced technologies.
Through their 6G trials with the three abovementioned vendors as well as other
partners, DOCOMO and NTT look forward to accelerating the global standardization
and commercialization of 6G.
Shingo Mizuno, EVP of Fujitsu Limited
comments: "We are excited to start collaboration with DOCOMO and NTT to work
toward the realization of practical applications for 6G. Fujitsu positions
network technology as an essential element in its efforts to deliver business
transformation through digital innovation and ultimately achieve a more
sustainable society. We are confident that our involvement in the research and
development of 6G technologies will contribute to solving societal issues in
keeping with this vision of a sustainable future."
Kawamura, Executive Vice President, NEC Corporation said: "We are pleased to
expand our collaboration with DOCOMO and NTT in the development of 6G, which
represents an important foundation that will accelerate the fusion of the
digital and real world, connect things and experiences on a global scale, and
provide new value to society. Moreover, this will contribute to the achievement
of the NTT Group's IOWN initiative as we actively promote research and
development toward the realization of 6G and a more prosperous society."
Peter Vetter, President Bell Labs Core
Research, Nokia, said: "It is an honor for Nokia to collaborate with DOCOMO and
NTT to jointly define and develop key technologies towards 6G. Nokia and DOCOMO
have a long-lasting relationship in early joint research, and DOCOMO is always
among the first operators to bring new generations to the market. We look
forward to working together to validate AI native air interface and
sub-terahertz proof-of-concepts that will help bring 6G to life."
