Huawei and NTT DOCOMO recently completed a 5G trial using the 39 GHz mmWave technology based on 3GPP 5G New Radio (NR) standard.
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, said 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 (Meta-Material Focal Array) and Polar Code.
After signing a 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.
