• Abstract: 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, 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.

• Pragmatic Goal-Oriented Communications under Semantic-Effectiveness Channel Errors [3.266331042379877]
  In forthcoming AI-assisted 6G networks, integrating semantic, pragmatic, and goal-oriented communication strategies becomes imperative. This paper proposes and details a novel mathematical modeling of errors stemming from language mismatches at both semantic and effectiveness levels. Our numerical results show the potential of the proposed mechanism to compensate for language mismatches, thereby enhancing the attainability of reliable communication under noisy communication environments.

  This paper explores opportunities and challenges of task (goal)-oriented and semantic communications for next-generation (NextG) networks through the integration of multi-task learning. We employ deep neural networks representing a dedicated encoder at the transmitter and multiple task-specific decoders at the receiver. We scrutinize potential vulnerabilities stemming from adversarial attacks during both training and testing phases.

  A novel implicit semantic-aware communication (iSAC) architecture is proposed for representing, communicating, and interpreting the implicit semantic meaning between source and destination users. A projection-based semantic encoder is proposed to convert the high-dimensional graphical representation of explicit semantics into a low-dimensional semantic constellation space for efficient physical channel transmission. A generative adversarial imitation learning-based solution, called G-RML, is proposed to enable the destination user to learn and imitate the implicit semantic reasoning process of source user.

  We present the first rigorous vision of a scalable end-to-end semantic communication network. We first discuss how the design of semantic communication networks requires a move from data-driven networks towards knowledge-driven ones. By using semantic representation and languages, we show that the traditional transmitter and receiver now become a teacher and apprentice.

  Despite its promising potential, semantic communications and semantic-aware networking are still at their infancy. We propose a novel reasoning-based implicit semantic-aware communication network architecture that allows multiple tiers of CDC and edge servers to collaborate. We introduce a new multi-layer representation of semantic information taking into consideration both the hierarchical structure of implicit semantics as well as the personalized inference preference of individual users.

A novel top-down framework that combines curriculum learning (CL) and reinforcement learning (RL) is proposed to solve this problem. Simulation results show that the proposed CL method outperforms traditional RL in terms of convergence time, task execution time, and transmission cost during training.
