摘　　要：作为未来6G网络的关键技术之一,通信感知计算一体化是实现扩展现实及视频传输的重要手段和方法。因此,首先介绍了通信感知计算一体化技术、扩展现实技术及其通信感知计算一体化技术支撑扩展现实业务实现;其次,探讨了基于通信感知计算一体化的扩展现实视频传输关键技术,如通信感知计算一体化波形设计、联合信源信道编码和边缘计算赋能的多径路由选择等;最后,分析了扩展现实用户体验质量评价建模实现方法,提出并设计了一种新的用户体验质量模型。As one of the key technologies of the future 6G network, integrated communication, sensing and computation(ICSC) is an important means to achieve extended reality(XR) and video transmission. Firstly, the technologies of ICSC and XR are respectively introduced, as well as the implementation of XR services supported by ICSC technology. Secondly, the key technologies of XR video transmission based on ICSC are explored, such as the ICSC waveform design, joint source-channel coding, and multi-path route selection enabled by edge computing. Finally, the implementation method of modeling the Qo E of XR users is analyzed, and a new user Qo E model is proposed.
