摘　　要：内生智能技术通过网络架构与人工智能技术的深度融合,全面提升网络的智能化水平。作为6G内生智能网络的核心技术之一,语义通信基于人工智能技术对信源数据进行语义信息的提取与压缩,大幅减小传输带宽消耗,提升通信的可靠性。然而语义通信技术的应用需要大量计算资源,提出了一个算力网络驱动的语义通信系统,涵盖了云边端协同计算驱动的语义采样与语义-信道联合编码、语义感知的资源分配和优化等基于云边端协同计算的关键语义通信技术,旨在为语义处理和传输提供足够的计算资源,实现内生计算能力与通信的深度融合。最后通过实验仿真证明了所提出的算力网络驱动的语义通信系统的优势。Endogenous intelligence technology enhances network intelligence through the deep integration of network architecture andartificial intelligence technologies. As a core technology of 6G endogenous intelligent networks, semantic communicationleverages AI to extract and compress semantic information from source data, significantly reducing transmission bandwidthconsumption and improving communication reliability. However, the application of semantic communication requiressubstantial computation resources. This paper proposes a computing network-driven semantic communication system,which encompasses key technologies such as semantic sampling and semantic-channel joint coding driven by cloud-edgedevicecollaborative computing, as well as semantic-aware resource allocation and optimization. The system aims to providesufficient computation resources for semantic processing and transmission, achieving deep integration of endogenouscomputing capability and communication. Experimental simulations demonstrate the advantages of the proposed computingnetwork-driven semantic communication system.
