【摘要】 沉浸式通信是6G的重要应用场景之一，目标是通过利用人的感官和认知，为用户营造仿佛身临其境的体验。首先讨论了6G沉浸式通信的典型应用场景，主要包括扩展现实、全息通信、触觉互联。其次，探讨了6G沉浸式通信对超大带宽、低时延、高可靠和多感官同步的服务质量需求与移动网络面临的挑战。然后，深入分析了能够为沉浸式通信提供支撑的智简空口技术，如联合信源信道编码技术、语义通信信道状态信息反馈技术、语义通信双工技术、语义知识库技术，以及语义多址接入技术。最后，对未来沉浸式通信的发展进行了总结与展望。更多还原

【Abstract】 Immersive communication is regarded as one of the key application scenarios of sixth-generation(6G) networks, aiming to create a lifelike experience for users by leveraging human perception and cognition. This paper first discusses the typical use cases of 6G immersive communication, including extended reality, holographic-type communication, and haptic interaction. It then explores the stringent quality-of-service requirements—such as ultra-wide bandwidth, low latency, high reliability, and multi-sensory synchronization—together with the challenges they impose on mobile networks. Subsequently, the paper provides an in-depth analysis of intellicise radio technologies that can support immersive communication, including joint source–channel coding, semantic communication-based channel state information feedback, semantic full-duplex techniques, semantic knowledge base construction, and semantic multiple access. Finally, future development prospects of immersive communication are summarized and discussed.更多还原
