(Reporter Zhang Yingjie) As an important engine for promoting the digital transformation of the economy and society, 5G is empowering thousands of industries to move from vision to reality. China Telecom recently joined hands with and Huawei to jointly release the key 5G deterministic network wireless technology - "Super Time-Frequency Folding" to accelerate the deep integration of 5G into core production links and fully empower the digital upgrade of the industry.
Super Time and Frequency Folding Joint Release Ceremony
Super Time and Frequency Folding is another innovation by Telecom and Huawei to provide gigabit capabilities to industry scenarios. Super time-frequency folding folds the TDD carrier, and uses dual-carrier uplink and downlink time domain complementation to simulate the FDD full time slot uplink and downlink air interface. At the same time, through three-domain collaboration and cross-layer service scheduling in the time domain, frequency domain, and air domain, it finally achieves end-to-end The terminal delay is within 4ms, the delay is reduced by more than 60%, the uplink and downlink equivalent bandwidth is 100MHz, and the reliability is the highest deterministic network capability of 6 9s. It is suitable for all classic 5G TDD frequency bands and better matches the determinism of core production links. Network needs can meet about 80% of production links.
It is reported that China has more than 10,000 5G innovative application cases, continuing to lead the world in accelerating 5G development and giving birth to a new ecosystem of integration and mutual promotion. In 2019, China Telecom and China Unicom opened the innovative path of "5G co-construction and sharing" and continued to lead in technology, operations, business and other aspects. China Telecom launched three types of 5G customized networks: "Zhiyuan, Linlin and Ruyi" , has covered all 30 key vertical industries such as mining, ports, electric power, and industrial manufacturing. Deep integration of 5G with vertical industries and comprehensive empowerment of industry digitalization are important ways to unleash the huge potential of 5G.
Liu Guiqing, deputy general manager of China Telecom, pointed out that from ToC to ToB, 5G customized networks not only serve the auxiliary production links of the industry, but also enter the core production links of the industry. They need to break through the traditional network's "best effort" ability and have end-to-end capabilities. Deterministic network capabilities to “walk the talk” on the end. China Telecom is willing to join hands with all parties in the industry to continue to promote technology and model innovation, jointly explore and research 5G deterministic network wireless key technologies, and build 5G deterministic network atomic capabilities, 5G deterministic basic capabilities, and 5G deterministic common business flow capabilities. , deeply integrating core production links and empowering thousands of industries!
