Enhanced Scheduling Strategy and Energy Efficiency for Extended Reality in 5G Advanced

Extended Reality, aka XR, is a promising technology which is expected to usher in an era of digital twin and meta-universe. 5G Advanced is directed to provide a communication framework to support XR applications and which, in turn, requires significant enhancements on the resource scheduling front to simultaneously fulfil low latency, high reliability and high data-rate requirements for XR. This paper provides a new scheduling strategy which effectively integrates frame-integrity and energy-efficiency awareness as prime factors in the XR scheduler design framework. With simulations we demonstrate the proposed approach outperforms traditional packet based scheduling approaches used in cellular communication networks, and achieves significant gains in terms of capacity enhancement and power saving performance.
