Huawei, NTT DoCoMo carry out 5G trial in Yokohama

Both companies will continue 5G trial activities in Japan

Chinese vendor Huawei and Japanese mobile operator NTT Docomo have carried out a large-scale 5G trial in the 4.5 GHz band in Yokohama, Japan.

During the trial, 11.29 Gbps total user throughput and less than 0.5 millisecond one way user plane latency were achieved in the macro cell coverage of a real urban application scenario, Huawei said.  

The 5G trial was performed in Yokohama Minato Mirai 21 District, which is one of the largest commercial areas in Japan. The macro cell was made up with one base station that works in the 4.5 GHz band with 200 megahertz bandwidth.

In December 2014, Huawei and NTT Docomo signed an agreement to carry out 5G field trials. The first 5G trial of Massive MIMO technology was carried out in October 2015, in Chengdu, China.

Currently, the two companies are moving their large scale field trial to Japan and continue the  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.

“Our success in 5G large-scale field trial in the 4.5 GHz band brought the whole industry one step closer to 5G commercialization by 2020. DOCOMO and Huawei have been expanding their collaboration on 5G from R&D to international spectrum harmonization initiatives for 5G since December 2014,” Takehiro Nakamura, VP and Managing Director of NTT DOCOMO’s 5G Laboratory, said. “Together with Huawei, we will continue to promote 5G both from technical and ecosystem perspective.”
