论文摘要
蜂窝连接的无线连接为虚拟现实（VR）提供了新的机会，可以随时随地提供无缝的用户体验。要实现这一愿景，需要仔细定义无线VR的服务质量（QoS），以反映人类的感知要求。在本文中，我们首先就应用程序和用例来确定VR系统的主要驱动因素。然后，我们将人类的感知要求映射到VR技术开发四个阶段的相应QoS要求。为了阐明如何为VR服务提供短/远程移动性，我们进一步列出了四个主要用例，用于蜂窝连接的无线VR，并确定其独特的研究挑战，以及他们在5G系统及其他地区的相应启用技术和解决方案。最后但并非最不重要的一点是，我们提出了一个案例研究，以证明我们提出的解决方案的有效性以及与蜂窝网络中传统视频服务相比，VR传输的独特QoS性能要求。
Cellular-connected wireless connectivity provides new opportunities for virtual reality(VR) to offer seamless user experience from anywhere at anytime. To realize this vision, the quality-of-service (QoS) for wireless VR needs to be carefully defined to reflect human perception requirements. In this paper, we first identify the primary drivers of VR systems, in terms of applications and use cases. We then map the human perception requirements to corresponding QoS requirements for four phases of VR technology development. To shed light on how to provide short/long-range mobility for VR services, we further list four main use cases for cellular-connected wireless VR and identify their unique research challenges along with their corresponding enabling technologies and solutions in 5G systems and beyond. Last but not least, we present a case study to demonstrate the effectiveness of our proposed solution and the unique QoS performance requirements of VR transmission compared with that of traditional video service in cellular networks.
