Recently, the China Institute of Communications commended the achievements of the 2023 China Institute of Communications Science and Technology Award. The "Research and Application of Key Technologies of "5G + Beidou" Communication and Conduction Integration" led by China Unicom Smart City Research Institute (hereinafter referred to as "China Unicom Intelligent Research Institute") won the second prize of Science and Technology AwardIt fully reflects China Unicom's excellent achievements in scientific and technological innovation and landing application in the field of "5G + Beidou" communication and guidance integration, and further enhances the industry influence in the field of time and space.
5G and Beidou are two indispensable underlying technologies for digitalization and intelligence in various industriesResearch and Application of Key Technologies of "5G + Beidou" Communication and Conduction IntegrationFocusing on the "5G + Beidou" communication and navigation integration direction, the innovative positioning method based on 5G Uplink Arrival Time Difference (UTDOA) and positioning optimization model, based on 5G large-scale antenna beam combined with RSU signal correction, effectively improves the 5G positioning accuracy under NLOS (non-direct diameter) conditions, reduces the overall cost by 20%, and shortens the delivery time by 40%.In view of the complex working conditions of ports and factories, a multi-source signal fusion pose measurement method based on high-precision phase measurement is developed, and the dynamic pose accuracy is better than 03°. The positioning accuracy reaches the centimeter level.
China Unicom Intelligent Research InstituteThe scientific research achievements in the field of time and space are closely combined with China Unicom's 5G capabilities to build a 5G + Beidou "Xuanji" space-time platform, which has six major spatio-temporal capabilities, including "outdoor high-precision positioning, indoor 5G fusion positioning, Beidou short message, remote sensing, spatio-temporal PaaS, and geographic information", and has developed more than 30 "space-time +" industry application products for smart cities, transportation and logistics, industrial Internet, ecological and environmental protection, cultural tourism and other industries, and has built a total of Sany Renewable Energy wind power equipment manufacturing, Nearly 60 commercial applications have been applied in Shandong small reservoir monitoring, Guoneng Huanghua Port automated port, unmanned operation of Hong Kong Airport, and Henan county smart city. The relevant achievements were selected as the top ten application cases of the 2023 World 5G Conference, and won the second prize of the 6th 5G Application Blooming Cup National Competition, the application gold medal of the China Satellite Navigation and Positioning Association and other awards.
Facing the future, China Unicom will continue to actively implement the national strategy, give full play to the advantages of operators' basic network resources and rich experience in industry empowerment, continue to adhere to the application-oriented, accelerate the "5G + Beidou" core technology research, product research and development and achievement promotion, and build a more comprehensive "space-time +" digital intelligence base, further promote the development of Beidou industrialization, empower industrial digitalization and intelligent transformation and upgrading, and help the implementation of the network power and digital China strategy.
