Abstract

Extended Reality (XR), an umbrella abbreviation for Cloud Gaming/Augmented Reality/Virtual Reality, is supposed to deliver the commercial outlook for 5G networks. This paper discusses the challenges incurred by this service due to its inherent stringent requirements from a data rate, reliability and latency perspective. To address the challenges, a novel priority-based adaptive preemption/cancellation strategy is proposed to guarantee the new radio quality of service under both the multi-streams XR service and XR in concurrent transmission with other services scenarios. Simulation results demonstrate that a scheduler devised based on the principle of the proposed strategy is quite useful from a capacity perspective. In the meantime, a synthesis of the industrial consideration and vision is provided featuring the ongoing the 3rd Group Partnership Project Release-17 XR study item.
迈向一个强大的新无线电兼容XR
扩展现实(XR)是云游戏/增强现实/虚拟现实的缩写,有望为5G网络提供商业前景。本文从数据速率、可靠性和延迟的角度讨论了该服务由于其固有的严格要求而带来的挑战。针对这一挑战,提出了一种基于优先级的自适应抢占/取消策略,以保证多流XR业务和XR与其他业务并发传输场景下新的无线电业务质量。仿真结果表明,从容量的角度来看,基于该策略设计的调度程序是非常有用的。与此同时,提供了一个综合的工业考虑和愿景,特色是正在进行的第三集团合作伙伴项目发布-17 XR研究项目。
