How iQIYI and Huawei Cut Edge Latency Below 10 ms with 5G MEC for VR & 8K Video

In June 2019 China issued its first 5G licences, sparking expectations that the new network would enable VR/AR experiences and 4K/8K ultra‑high‑definition video, but high compute costs, bulky hardware and insufficient bandwidth caused latency‑induced motion sickness that limited mass adoption.

Leveraging Huawei’s leading 5G MEC platform and iQIYI’s extensive CDN scheduling expertise, the two companies jointly designed and validated an edge‑acceleration solution in Huawei’s cLab innovation lab. The proof‑of‑concept demonstrated that end‑to‑end latency could be reduced from 60 ms to below 10 ms, dramatically lowering the computational burden of VR applications, eliminating motion‑sickness, and improving the quality of ultra‑HD video playback.

The pilot adopted a terminal‑edge‑cloud perception scheme that requires minimal changes to the existing network, offering strong universality and suitability for large‑scale deployment. Compared with other edge‑service scheduling approaches—such as outbound‑IP awareness, DNS‑based, HTTP‑based, or TCP‑based methods—this solution overcomes their technical limitations and facilitates faster commercial rollout of MEC services.

Beyond latency reduction, the approach increased download speeds for 1080p and 4K VR video by 400%, making seamless 4K/8K streaming feasible anywhere and opening a potential multi‑trillion‑yuan market for ultra‑high‑definition video content.

Looking ahead, iQIYI and Huawei plan to co‑develop MEC industry standards and explore further 5G‑driven video applications, including VR, AR, MR, and 4K/8K streaming, while continuing joint R&D labs with major carriers to accelerate commercial adoption.
