Tong Wen, Chief Scientist of Huawei 5G: 5.5G is the only way to evolve from 5G to 6G

With the continuous development of 5G, the 5G industry is becoming more and more perfect. At the 2022 Huawei Win-Win Innovation Week held on July 18 this year, Huawei put forward the concept of " moving towards the 5.5G era in an all-round way ", hoping to further improve the user network experience.

According to Huawei's official report, on September 8, at the 8th IC&E Summit held by NGMN (Next Generation Mobile Network), Huawei Fellow and Huawei Wireless CTO and 5G Chief Scientist Dr. Tong Wen made the theme "Bridging 5G to 6G". " speech. He said that 5.5G is the only way for the evolution from 5G to 6G.

Tong Wen said that 5G is booming around the world, with a maximum of 40 5G sites per 10,000 population. In China, 5G has been applied to more than 30 vertical industries, and the total economic volume directly driven by 5G will reach 1.3 trillion US dollars in 2021. In order to meet the new requirements for 5G from to C new services and to B industry applications, 5G will continue to innovate towards 5.5G and achieve continuous enhancement of eMBB / URLLC / mMTC capabilities.

In order to realize the 5.5G network of "downlink 10Gbps and uplink 1Gbps", on the one hand, on the basis of the existing nearly 100MHz FDD frequency band and nearly 100MHz TDD frequency band, introduce a larger bandwidth 6GHz to provide 200MHz-400MHz spectrum, and introduce millimeter wave to provide 800MHz spectrum, making it possible to experience 10Gbps anytime, anywhere. On the other hand, it is necessary to make full use of the existing FDD spectrum, define the full uplink spectrum, realize multi-frequency fusion through uplink and downlink decoupling, and provide a 1Gbps uplink rate.

Wang Tao, Huawei's executive director and director of the ICT Infrastructure Business Management Committee, said in July this year that the 10Gbps network access rate will gradually become popular in the future. In addition, Xu Wenwei, director of Huawei and dean of the Strategic Research Institute, also pointed out that 5.5G is the next step in the wireless communication industry. 5.5G comes from 5G and needs to be compatible with all 5G devices.
