Huawei showcases 5G Live Demo with NTT DOCOMO in Japan

NEW DELHI: Recently, at the 3rd Global 5G Tokyo Bay Summit, Huawei successfully showed 39 GHz mmWave technology based on 3GPP standard 5G New Radio (NR) current agreements in cooperation with NTT DOCOMO.

"The cell coverage reached up to 2.0 kilometers with Gbps peak throughput for a single user in the mmWave. With this system, a real-time 3-way 4K video conference was demonstrated," a statement said.

"The result of the field test represents the 5G joint innovation between Huawei and NTT DOCOMO, who have achieved a new milestone. This breakthrough will have a significant impact in moving 5G a step closer to commercialization," it said.

Takehiro Nakamura, General Manager of NTT DOCOMO’s 5G Laboratory said, “The successful field tests and showcase of the real-time 3-way 4K video conference conducted at 39 GHz high frequency band technology is an important achievement of the 5G joint innovation and field trial between Huawei and DOCOMO, which we will push forward for the development of 5G industry collaborating with Huawei.”

The field test was performed in Yokohama Minato Mirai 21 District, which is one of the largest commercial areas in Japan. The test system was made up of one base station that works in the 39 GHz band with 1.4 GHz bandwidth, and 2 UEs (User Equipment). According to the test, 1.3 Gbps (MAC Layer) peak throughput for a single user in the high band was achieved at a distance of 1.5 kilometers. The test employed key 5G technologies, such as the MMFA (Metal-Material Focal Array) and Polar Code.

After signing a MoU on partnership in 5G joint field trials in December 2014, Huawei and DOCOMO successfully conducted the world’s first large-scale outdoor field trial of Massive MIMO in Chengdu, China in October 2015. Currently, the two companies continue the systematic verification of 5G key technologies such as Massive MIMO, ultra-reliability and low latency, mixed numerology using f-OFDM (filtered OFDM), and combined performance of SCMA (Sparse Code Multiple Access), Polar Code and f-OFDM. In November 2016, The trial achieved 11.29 Gbps aggregated User Throughput with Less than 0.5 Millisecond One Way User Plane Latency in Yokohama, Japan.

Dr. Wen Tong, Huawei Fellow and CTO of Huawei Wireless Networks, said, “The successful field test of the 39 GHz band is an important technical contribution to the 5G community for the two companies, and it will help to lay the foundation work for 5G tests and deployment globally. Huawei will continue investing in R&D and enhance its cooperation with partners to make progress in 5G technology and the development of an industry ecosystem.”

5G can provide an excellent user experience with its high transmission speed and low latency, and will enable the next generation of eMBB applications such as VR (virtual reality) and AR (augmented reality). 5G will fundamentally change society and daily life.
