Huawei Technologies announced it has successfully showcased a live demo of 39-GHz mmWave technology in cooperation with NTT DoCoMo at the recent Global 5G Tokyo Bay Summit. The demo achieved 1.3 Gbps (MAC Layer) peak throughput for a single user at a distance of 1.5 km whilst supporting a real-time 3-way 4K video conference.
The field test was performed in Yokohama Minato Mirai 21 District, one of the largest commercial areas in Japan. The test system comprised one base station utilizing 1.4 GHz of bandwidth in the 39-GHz band, and two user equipment terminals. The test employed key 5G technologies, such as the MMFA (Meta-Material Focal Array) and Polar Code.
Takehiro Nakamura, General Manager of NTT DoCoMo 5G Laboratory said the field tests and 4K video conference demo was “an important achievement of the 5G joint innovation and field trial between Huawei and DoCoMo.”
Huawei and DoCoMo signed a MoU in December 2014 to partner on 5G joint field trials. Since then, the two companies successfully conducted a large-scale outdoor field trial of massive MIMO in Chengdu, China in October 2015. They are continuing 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, another trial achieved 11.29 Gbps aggregated user throughput with less than 0.5 millisecond one-way user-plane latency in Yokohama.
