Beijing (Gasgoo)- China Unicom announced on December 9 that the company and Huawei recently co-established China's first 5G-A V2X innovation base in Beijing Economic-Technological Development Area. The initiative marks a significant milestone in the in-depth application of 5G-A technology for integrated vehicle-road-cloud systems.
The collaboration between China Unicom and Huawei focuses on advanced 5G-A features, AI-powered perception, and automotive-grade RedCap terminals. The project is driving innovations in intelligent driving and smart parking applications, particularly in beyond-line-of-sight scenarios.
The innovation base is equipped with six roadside sensing systems, six 5G-A pole stations, four multimodal fusion engines, and a unified sensing-communication base station. Key technologies such as multi-carrier aggregation, supplemental uplink, and deterministic low-latency transmission have been validated. Additionally, Huawei's multimodal fusion engine integrates seamlessly with China Unicom's intelligent vehicle-road collaboration platform, enabling real-time data fusion.
The base has established a robust 5G-A network across Beijing, leveraging China Unicom's commercial 3.5GHz and 2.1GHz frequency bands. It achieves sub-20 ms latency and uplink speeds exceeding 20 Mbps, laying a solid foundation for large-scale 5G V2X adoption.
In practical applications, 5G-A enables real-time data exchange and intelligent coordination between vehicles, roads, and the cloud. Verification scenarios, such as oncoming vehicle alerts and secondary collision avoidance, demonstrate sub-10 ms end-to-end latency, achieving comprehensive, real-time road perception.
The base also advances RedCap terminal ecosystem development, with tests conducted in cities like Foshan and Beijing. The integration of commercial RedCap terminals into vehicles is expected to enhance connectivity performance and accelerate 5G adoption in the automotive sector.
