DOCOMO trials 5G aboard Shinkansen test train running at 360km/h

NTT DOCOMO verified the stable operation of 5G, including handover between base stations and the transmission of high-definition video data, aboard JR East's ALFA-X1 Shinkansen test train running at 360km/h. The trials confirmed that it will be possible to ensure stable mobile communication environments on high-speed trains for the delivery of high-value mobile services.

In general, communication quality at high speed becomes unstable due to the influence of direct-path obstructions and the Doppler effect. This is especially true in the case of 5G, which uses relatively high frequency bands that are more sensitive to physical obstructions and the Doppler effect compared to lower frequency bands used in legacy mobile communication networks.

Specifically, the trials confirmed the following three results aboard ALFA-X running at 360km/h:

Maximum data rates exceeding 500Mbps and 100Mbps in the downlink and uplink, respectively, were verified and highly stable communication at 100Mbps or higher was achieved over a distance of approximately 5km, confirming the possibility of practical, reliable communication.

Successful handover was confirmed while maintaining data rates at 100Mbps or higher.

Both 4K and 8K high-definition video data transmissions were achieved, confirming the possibility of stable, large-capacity data transmissions.

NTT DOCOMO tests 5G transparent metasurface

NTT DOCOMO is testing a prototype transparent dynamic metasurface using 28 GHz 5G radio signals.

The new metasurface, which was developed in collaboration with global glass manufacturer AGC Inc., achieves dynamic manipulation of radio-wave reflection and penetration in a highly transparent package suitable for unobtrusive use in the windows of buildings and vehicles as well as on billboards. AGC manufactured the optically transparent metasurface using microfabrication techniques, based on a theoretical model proposed and designed by DOCOMO.

NTT DOCOMO said the metasurface can manipulate radio waves in accordance with the specific installation environment, particularly in locations not suited to the installation of base stations, such as built-up areas or in indoor areas where reception needs to be blocked selectively, such as in high-security areas.

The metasurface consists of a large number of sub-wavelength unit cells placed in a periodic arrangement on a two-dimensional surface covered with a glass substrate. Moving the glass substrate slightly enables dynamic control of radio waves in three modes: full penetration of incident radio waves, partial reflection of incident radio waves and full reflection of all radio waves. Compared to conventional methods using semiconductors, this new design offers two advantages: it allows dynamic control while maintaining transparency of the window and it facilitates enlargement of the substrate.

The prototype transparent dynamic metasurface will be presented during DOCOMO Open House 2020, which will take place in the Tokyo Big Sight exhibition complex in Tokyo this week.

NTT DOCOMO and MobiledgeX to conduct MEC demo

NTT DOCOMO and MobiledgeX will jointly conduct a proof of concept (PoC) in Tokyo on January 22–24 to verify a solution that leverages multi-access edge computing (MEC) for the worldwide distribution of applications.

In the PoC, a “markerless” augmented-reality (AR) application based on the Edge Realities platform offered by 1000 realities, a Poland-based software studio, will be distributed to the MEC platform, DOCOMO Open Innovation Cloud, connected to 5G and LTE networks operated by DOCOMO in Japan. Edge Realities uses space-recognition technology to superimpose AR content on real objects and large spaces without using place markers. Thanks to outsourcing all computation to the MEC platform and its low-latency network, Edge Realities will be fully hardware agnostic and useable on hardware that does not have native AR capabilities. The MEC platform will enable the content to be positioned in space and displayed, without any time lag. Tanseisha Co., Ltd. and DOCOMO Innovations, Inc. will support the PoC. The event will take place in the Tokyo Big Sight exhibition complex in Tokyo.

MobiledgeX’s solution offers a developer portal site for distributing applications to MEC infrastructure, such as servers and storage systems, located on the edges of mobile operator networks that are close to customers in markets overseas.

DOCOMO and MobiledgeX aim to collaborate on a range of 5G solutions for the global market, which will be distributed in cooperation with partners in Japan and other countries.

DOCOMO commits to multivendor O-RAN for 4G/5G

NTT DOCOMO has commenced deployment of a 4G/5G multivendor radio access network conforming to O-RAN specifications.

Working in collaboration with Fujitsu, NEC, and Nokia, DOCOMO has demonstrated multi-vendor interoperability across a variety of 4G and 5G base station equipment compatible with O-RAN. The O-RAN standards include fronthaul specifications and X2 profile specifications.

O-RAN fronthaul specifications are used to establish the connections between centralized units hosting baseband processing and remote units hosting radio processing in 5G remote-installed base stations. O-RAN fronthaul interface specifications provide a foundation for interoperability between centralized units and remote units of 5G remote-installed base stations manufactured by diverse partners.

The O-RAN X2 profile specifications provide a foundation for interoperability between 4G base stations and 5G base stations manufactured by diverse partners in 5G non-standalone (5G NSA) networks by taking 3GPP X2 interface specifications and specifying detailed standards for their usage. 5G NSA networks connect devices using both 4G and 5G technologies.

DOCOMO believes this represents the world's first realization of this level of multi-vendor interoperability in 4G and 5G base station equipment conforming to O-RAN specifications. The ability to deploy and interconnect base station equipment from different vendors will make it possible to select the equipment most suitable for deployment in any given environment, such as base stations offering broad coverage in rural areas or small base stations that can be deployed in urban areas where space is limited.

DOCOMO will deploy the equipment in the pre-commercial 5G service it plans to launch on September 20, 2019 in Japan.
