Extended Reality (XR) optimization: bounded latency, jitter control

XR Traffic Characteristics and QoS Requirements

Extended Reality applications — virtual reality, augmented reality, and mixed reality — present unique challenges for 5G networks. XR traffic is periodic with video frames generated at 60-120 fps, creating bursty patterns with strict per-frame deadlines. A VR headset requires 10-20 ms motion-to-photon latency to prevent motion sickness, translating to approximately 7-10 ms one-way air interface budget. Downlink data rates range from 50-200 Mbps for 4K stereoscopic rendering. Unlike traditional video streaming which uses buffering, XR cannot tolerate buffering delays — each frame must be…
