论文摘要
扩展现实（XR）是在5G/5G高级通信系统中引入的主要创新之一。增强现实，虚拟现实和混合现实的结合，补充了云游戏，重新审视了人类与计算机，网络和彼此之间的互动方式。但是，XR服务的有效支持对现有和未来的无线网络构成了新的挑战。本文介绍了将XR支持集成到3GPP新广播（NR）的教程，总结了在各种3GPP服务和系统方面（SA）和无线电访问网络（RAN）组中处理的一系列活动。该文章还提供了一项案例研究，评估了最先进的NR版本17中不同XR服务的性能。本文以进一步的增强愿景结论，以更好地支持XR，以在未来的NR版本中更好地支持XR，并在该领域概述了开放问题。
Extended Reality (XR) is one of the major innovations to be introduced in 5G/5G-Advanced communication systems. A combination of augmented reality, virtual reality, and mixed reality, supplemented by cloud gaming, revisits the way how humans interact with computers, networks, and each other. However, efficient support of XR services imposes new challenges for existing and future wireless networks. This article presents a tutorial on integrating support for the XR into the 3GPP New Radio (NR), summarizing a range of activities handled within various 3GPP Service and Systems Aspects (SA) and Radio Access Networks (RAN) groups. The article also delivers a case study evaluating the performance of different XR services in state-of-the-art NR Release 17. The paper concludes with a vision of further enhancements to better support XR in future NR releases and outlines open problems in this area.
