迄今为止的通信系统主要旨在可靠地传送比特序列。这种方法提供了高效的工程设计，这些设计对消息的含义或消息交换旨在实现的目标是不可知的。然而，下一代系统可以通过将消息语义和通信目标折叠到它们的设计中来潜在地丰富。此外，可以使这些系统认识到通信交换发生的上下文，从而为新颖的设计见解提供途径。本教程总结了迄今为止的努力，从早期的适应，语义感知和面向任务的通信开始，涵盖了基础，算法和潜在的实现。重点是利用信息理论提供基础的方法，以及学习在语义和任务感知通信中的重要作用。
Communication systems to date primarily aim at reliably communicating bit sequences. Such an approach provides efficient engineering designs that are agnostic to the meanings of the messages or to the goal that the message exchange aims to achieve. Next generation systems, however, can be potentially enriched by folding message semantics and goals of communication into their design. Further, these systems can be made cognizant of the context in which communication exchange takes place, thereby providing avenues for novel design insights. This tutorial summarizes the efforts to date, starting from its early adaptations, semantic-aware and task-oriented communications, covering the foundations, algorithms and potential implementations. The focus is on approaches that utilize information theory to provide the foundations, as well as the significant role of learning in semantics and task-aware communications.
