Today is the third anniversary of China’s 5G licensing. The 5G network speed currently in operation has hit 1Gbps. Now Huawei, China Mobile, and other companies have jointly released an enhanced version of 5G. This is the 5.5G network with up to 10Gbps downlink speed. Recall that the 5.5G name is in Huawei’s proposal sometime last year.
According to reports, China Mobile, Huawei, and other companies jointly released the “5G-Advanced (5G Expansion and Enhancement, hereinafter referred to as “5G-A”) New Capability and Industrial Development White Paper”, emphasizing that 5G-A “excellent network”, “Intelligent Health, Smart Simplicity”, “Low-Carbon Efficiency” and ten key technologies.
Through these key technologies, 5G-A will support a downlink 10Gbps peak rate as well as an uplink peak rate of 1Gbps. This technology also supports millisecond-level latency, low-cost 100 billion IoT, and capabilities beyond connection such as perception and high-precision positioning.
In April 2021, the 46th PCG (Project Cooperation Group) meeting was held. In that meeting, 3GPP officially identified the name of 5G evolution as 5G-Advanced. At the same time, the meeting decided that 5G-A will start from R18. Furthermore, the R18 version will be approved by the end of the year.
3GPP-approved 5G-A is the same as Huawei’s 5.5G
5G-A will define new goals and new capabilities for the development of 5G after 2025. Through comprehensive evolution and enhancement, 5G can generate greater social and economic value. 5G-A is the same as the 5.5G proposed by Huawei. Last year, Wang Tao, Huawei’s executive director and president of ICT products and solutions, said in his speech that 5.5G requires spectrum reconstruction, uplink enhancement, all-scenario IoT, and synaesthesia. The company will continue to innovate in six directions, including integration, an L4 autonomous driving network, and green and low carbon. It needs to achieve tenfold improvement in capacity. Furthermore, Huawei needs to build new network capabilities to achieve an excellent network.
Huawei releases “5G super time-frequency”
Huawei and China Telecom held a joint innovation conference in Beijing and officially released the key wireless technology for 5G deterministic networks – “Super Time-Frequency Folding”. Gan Bin, vice president of the wireless network product line of Huawei Technologies Co., Ltd., believes that the super time-frequency folding is another innovation of telecommunications> Furthermore, Huawei will provide gigabit capabilities to industry scenarios.
The joint laboratory verification shows that the super time-frequency folding can improve the uplink experience to more than 1Gbps. It can also reduce the delay to less than 4ms, and improve the reliability to 6 9s. It effectively supports 5G into the core production link.
