摘 要:扩展现实是一种新兴的信息交互方式,相较于音视频等信息模态,为用户提供了更有沉浸感的体验。通过研究扩展现实的发展趋势,总结了相关应用及产业的通信需求和业务特点,为6G网络下的内生AI功能在扩展现实网络中的应用提供参考。首先从高宽带和低时延的需求出发,提出扩展现实网络和语义通信融合的趋势,并分析了语义通信的传输有效性,介绍其面向内容的系统模块与框架。然后基于扩展现实的业务需求,针对信息系统架构、安全接入要求和算力承载,分析了支撑具体场景的关键技术,明确语义驱动的扩展现实网络的优越性。最后总结了扩展现实网络提供的新机遇,为扩展现实网络与基于语义的内生AI融合架构及关键技术提供发展思路。Extended reality is an emerging information interaction mode with a more immersive user experience than the audio and video information modes.By studying the development trend of the extended reality,this paper summarizes the communication requirements and service characteristics of related applications and industries,providing a reference for the application of inherent AI functions in extended reality networks under 6G networks.Firstly,we propose the fusion trend of extended reality networks and semantic communication from the requirements of high bandwidth and low latency.We also analyze the transmission effectivness of semantic communications and introduce the content-oriented system modules and framework.Next,based on the service requirements of extended reality,we analyze the key technologies supporting specific scenarios regarding information system architecture,secure access requirements,and computing power bearing,and the superiority of semantic-driven extended reality networks is clarified Finally,we summarize the new opportunities provided by extended reality networks,providing development ideas for the fusion architecture and key technologies of extended reality networks and semantic-based endogenous AI.
