5G • 5G-Advanced (Rel-18)
Uplink XR Video Streaming
High-Bandwidth Low-Latency Uplink Transport for Tele-Presence Cameras
Enhances uplink scheduling and MIMO codebooks to support continuous 4K 60fps video uploads from wearable spatial cameras and streaming drones.
Technical Explanation
While consumer XR emphasizes downlink streaming, tele-presence and industrial remote inspections require multi-camera headsets to upload continuous high-resolution 3D video. Rel-18 enhances uplink radio protocols with multi-TRP combining, carrier aggregation, and robust 64-QAM uplink modulation, enabling reliable 50 Mbps+ sustained video uploads from battery-operated devices.
Key Functions
- Delivers sustained 50 Mbps to 100 Mbps uplink throughput per wearable camera user
- Maintains sub-15 ms latency bounds on dense multi-camera uplink video streams
- Employs multi-TRP uplink reception to overcome individual tower shadowing
- Enables remote expert tele-mentoring, emergency response, and drone inspection
