摘要:

第六代(6G)网络预计会部署更大的多输入多输出(MIMO)阵列以支持大规模连接,这将增加物理层的开销和延迟。同时,新兴的6G需求,如沉浸式通信和环境感知,对传统信号处理提出了挑战。为解决这些问题,我们提出了"语义感知MIMO"范式,该范式利用专家模型和大模型来感知、利用和融合信道和源的内在语义以提高性能。此外,针对代表性的MIMO物理层任务,如随机接入活动检测、信道反馈和预编码,我们设计了专家模型,利用信道和源语义以获得更好的性能。此外,鉴于6G MIMO更加多样化功能,我们进一步探索大模型作为多任务语义感知MIMO的可扩展解决方案,并回顾了最近的进展及其优缺点。最后,我们讨论了专家模型和大模型赋能语义感知MIMO范式演变中的挑战、见解和前景。

英文摘要:

The sixth generation (6G) network is expected to deploy larger multiple-input multiple-output (MIMO) arrays to support massive connectivity, which will increase overhead and latency at the physical layer. Meanwhile, emerging 6G demands such as immersive communications and environmental sensing pose challenges to traditional signal processing. To address these issues, we propose the ``semantic-aware MIMO'' paradigm, which leverages specialist models and large models to perceive, utilize, and fuse the inherent semantics of channels and sources for improved performance. Moreover, for representative MIMO physical-layer tasks, e.g., random access activity detection, channel feedback, and precoding, we design specialist models that exploit channel and source semantics for better performance. Additionally, in view of the more diversified functions of 6G MIMO, we further explore large models as a scalable solution for multi-task semantic-aware MIMO and review recent advances along with their advantages and limitations. Finally, we discuss the challenges, insights, and prospects of the evolution of specialist models and large models empowered semantic-aware MIMO paradigms.
