Key Takeaways
-
AI will make critical real-time decisions in 6G networks that affect everything from network resource allocation to autonomous vehicle safety, creating an urgent need for transparency in how these systems operate.
-
"Black-box" AI decision-making poses a control risk that explainable AI (XAI) can help address by making the reasoning behind automated decisions understandable to both designers and users, reducing the danger of losing oversight over high-speed, data-intensive systems.
-
XAI applications span multiple 6G domains, including intelligent radio systems and zero-touch network management, as well as emerging use cases like Industry 5.0, indicating that explainability will be essential across diverse 6G applications rather than isolated to specific sectors.
-
The paper identifies significant research challenges ahead in implementing XAI for 6G, suggesting that while explainable AI is promising for responsible deployment, practical solutions for making these systems transparent at scale remain unsolved.
-
6G's "human-centric" vision depends on explainability, as the paper frames XAI not as optional but as fundamental to achieving trustworthy AI systems that maintain human understanding and control in next-generation networks.
Abstract
When 5G began its commercialisation journey around 2020, the discussion on the vision of 6G also surfaced. Researchers expect 6G to have higher bandwidth, coverage, reliability, energy efficiency, lower latency, and an integrated "human-centric" network system powered by artificial intelligence (AI). Such a 6G network will lead to an excessive number of automated decisions made in real-time. These decisions can range widely, from network resource allocation to collision avoidance for self-driving cars. However, the risk of losing control over decision-making may increase due to high-speed, data-intensive AI decision-making beyond designers' and users' comprehension. The promising explainable AI (XAI) methods can mitigate such risks by enhancing the transparency of the black-box AI decision-making process. This paper surveys the application of XAI towards the upcoming 6G age in every aspect, including 6G technologies (e.g., intelligent radio, zero-touch network management) and 6G use cases (e.g., industry 5.0). Moreover, we summarised the lessons learned from the recent attempts and outlined important research challenges in applying XAI for 6G in the near future.
