Abstract

With sub-millisecond latency, connectivity of up to 10 million devices per square kilometre, and terabit-per-second data rates, sixth-generation (6G) wireless networks promise revolutionary performance. However, the accompanying surge in energy consumption presents a major challenge to sustainability and global carbon neutrality goals. Consequently, power optimization has become a core design requirement for 6G systems.

This comprehensive review synthesizes and critically evaluates recent research on AI-driven power optimization in 6G networks, positioning artificial intelligence as the primary enabler of intelligent, adaptive, and autonomous energy management. The methodology is based on a systematic analysis of more than 130 research articles, surveys, and standards documents published between 2019 and 2025.

Key AI techniques—including Deep Learning (DL), Reinforcement Learning (RL), Federated Learning (FL), and Graph Neural Networks (GNNs)—are categorized and analyzed alongside emerging concepts such as AI-native network slicing, reconfigurable intelligent surface (RIS) optimization, and dynamic resource allocation. Reported results indicate that AI-based approaches can consistently reduce energy consumption by 20–40% while maintaining QoS requirements, with some studies demonstrating savings up to 60% and spectral efficiency gains of 29%.

In addition to achievements, this paper examines performance trade-offs, including computational complexity, privacy–accuracy balance in distributed learning, and scalability in ultra-dense network environments. Persistent challenges such as data scarcity, model interoperability, security risks, and the environmental impact of AI training are also discussed. Finally, the paper outlines future research directions encompassing smart energy grid integration, digital-twin-based evaluation, explainable AI (XAI), quantum-assisted optimization, and deep cross-layer intelligence. This work serves as a strategic roadmap for developing sustainable, high-performance, and truly intelligent 6G networks.
