TL;DR
This paper proposes a context-aware semantic and task-oriented communication paradigm for V2X systems, enabling CAVs to transmit only relevant information, thereby doubling communication efficiency and enhancing scalability in future 6G networks.
Contribution
It introduces a novel semantic and task-oriented V2X communication framework that leverages contextual information to improve efficiency and scalability.
Findings
Two-fold improvement in communication efficiency.
Significant scalability benefits for V2X networks.
Quantitative evaluation demonstrating relevance-based transmission advantages.
Abstract
The design of communication systems has traditionally focused on the reliable and timely delivery of data. However, the scalability challenges faced by the evolution to a 6G-driven society demand new communication paradigms that carefully curate the content being transmitted. This paper envisions a joint semantic and task-oriented communication paradigm where Connected and Autonomous Vehicles (CAVs) transmit only the information necessary to convey the desired meaning that is relevant to the intended receivers based on the communication context. The V2X domain offers a unique environment for the development of the envisioned semantic and task-oriented communications paradigm, as CAVs are native semantic devices, and the V2X domain is rich in contextual information. This contextual information can be leveraged to estimate the relevance that information may have for the intended…
