Immersive Services over 5G and Beyond Mobile Systems

摘要

5G and beyond mobile systems target a plethora of emerging industrial and entertainment verticals that incur extra overhead to the network. These verticals are characterized by vigorous, continuous, and conflicting requirements that make the desired system's mission strenuous and more challenging. These verticals, such as autonomous driving, will accommodate immersive services, including virtual reality/augmented reality (VR/AR) and Holography services. Immersive services, in particular, have strict requirements for latency, throughput, and positioning. This article discusses VR-based remote services' potential, which occupies an important place among immersive services such as remote surgery, remote space control, and remote driving of Unmanned Aerial Vehicles (UAVs) or cars. Such services require an ultra-low Glass-to-Glass latency to avoid any failure and accidents when remotely controlling devices. We evaluate an immersive remote control service from the end-to-end communication perspectives using different camera devices that stream real-time 360 degrees videos to a VR Head Mounted Device (HMD). The obtained results demonstrate the challenges of such service and the need for more advanced and optimized techniques, devices, and protocols to achieve less than 20 ms of Glass-to-Glass latency.
