DoCoMo achieves 11.29Gbps in 5G trial
In this article (5)
NTT DoCoMo and Huawei have achieved a peak speed of 11.29Gbps during a 5G large-scale field trial in the 4.5-GHz band.
The companies tested a 3GPP 5G New Radio compliant numerology and frame structure using macro cell coverage in a real-world scenario in Yokohama’s busy Minato Mirai 21 commercial district.
The trial also achieved a sub-0.5ms one way user plane latency. The macro cell was made up of one base station compatible with the 4.5-GHz band and 200 MHz bandwidth, as well as 64 transceivers and 23 user equipment devices.
According to the test, 11.29Gbps of user throughput was achieved in 24 layers, with each UE receiving two layers. Peak spectrum efficiency reached 79.82bps/Hz/cell.
“Our success in 5G large-scale field trial in the 4.5 GHz band has brought the whole industry one step closer to 5G commercialization by 2020,” commented Takehiro Nakamura, DoCoMo’s VP and 5G Laboratory managing director.
“DoCoMo and Huawei have been expanding their collaboration on 5G from R&D to international spectrum harmonization initiatives for 5G since December 2014. Together with Huawei, we will continue to promote 5G both from technical and ecosystem perspective.”
