The 6G-GOALS project comes at a pivotal moment in communications. Data traffic is soaring, driven by applications needing ultra-reliable, real-time connectivity. Autonomous vehicles must exchange data in milliseconds, collaborative robots require constant coordination, immersive extended reality demands seamless interaction, and mission-critical IoT relies on precise, timely exchanges. Current networks are content-blind, transmitting all data equally, even when redundant. This wastes energy and spectrum, strains infrastructures, and undermines sustainable, human-centric digitalisation. The challenge is not sending “more data faster,” but communicating smarter, transmitting only what matters.
6G-GOALS addresses this by shifting from throughput- and latency-based systems to semantic- and goal-oriented communication. Information is treated as meaningful content tied to outcomes. For humans, this means context-aware messages like augmented-reality guidance; for machines, task-relevant features such as compressed semantic maps. By embedding AI, machine learning, and semantic information theory into network design, the project enables communication that is intelligent, efficient, and task driven. It develops semantic representation and compression, time- and relevance-aware protocols, and orchestration that jointly optimises communication, computation, and energy. These innovations converge into a network of intelligence, where devices exchange only contextual, timely, sustainable information.
The impacts are significant. Scientifically, 6G-GOALS pioneers new semantic information models and metrics such as value of information, semantic fidelity, and task success rate. Economically, it enables efficient applications and strengthens Europe’s role in 6G standardisation through 3GPP, ETSI, and O-RAN. Societally, it supports sustainability by reducing data flows, energy use, and electromagnetic exposure, while enabling services in healthcare, mobility, and industry. In sum, 6G-GOALS redefines communication for the next decade. By replacing data-heavy models with semantic, goal-driven systems, it paves the way for connectivity that is intelligent, sustainable, and impactful.
