Extended reality (XR)-aided teleoperation has shown its potential in improving operating efficiency in mission-critical, information-rich, and complex scenarios. The multi-sensory XR devices introduce several new types of traffic with unique quality of service (QoS) requirements, which are usually defined by three measures: human perception, corresponding sensors, and present devices. To fulfill these requirements, cellular-sup-ported wireless connectivity can be a promising solution that can largely benefit robot-to-XR and XR-to-robot links. In this article, we present industrial and piloting use cases and identify the service bottleneck of each case. We then cover the QoS of robot-XR and XR-robot links by summarizing the sensors' parameters and processing procedures. To realize these use cases, we introduce potential solutions for each case with cellular connections. Finally, we build testbeds to investigate the effectiveness of supporting our proposed links using current wireless topologies.

XR辅助远程操作系统对5G / B5G的愿景

扩展现实（XR）辅助的远程操作已经显示出在关键任务，信息丰富和复杂的场景中提高操作效率的潜力。多传感器XR设备引入了几种具有独特服务质量（QoS）要求的新型流量，这些流量通常由以下三种方法定义：人类感知，相应的传感器和当前设备。为了满足这些要求，蜂窝支持的无线连接可以成为一种有前途的解决方案，它可以极大地受益于机器人到XR和XR到机器人的链接。在本文中，我们介绍了工业用例和试点用例，并确定了每种用例的服务瓶颈。然后，我们通过总结传感器的参数和处理过程来涵盖XR和XR机器人链接的QoS。为了实现这些用例，我们介绍了每种情况下蜂窝连接的潜在解决方案。最后，我们建立了测试平台，以研究使用当前的无线拓扑支持建议的链路的有效性。
