In 5G trials in Beijing, Huawei achieved data rates greater than 20 Gbps using 200 MHz bandwidth at 4.9 GHz. The test used a 5G new radio (NR) architecture with massive MIMO and polar code, according to the company.
China has proposed using C-Band spectrum — 3.3 to 3.6 and 4.8 to 5.0 GHz — for 5G services, with the 3.5 GHz band limited to indoor use.
The 4.9 GHz trial was conducted as part of China’s 5G Technology Research and Development Trial, organized by the IMT-2020 (5G) Promotion Group. Earlier this year, Huawei tested three scenarios at 3.5 GHz, and this latest trial provides data on performance at the higher band.
To support large-scale field tests, Huawei has thirty 5G terminals deployed at seven sites in the Huairou District of Beijing.
