Energy-Aware 6G Network Design: A Survey
🤖 AI Summary
6G networks face severe energy-efficiency and sustainability challenges due to massive connectivity and data-intensive applications. This paper systematically surveys energy-aware design methodologies for 6G, covering energy harvesting, fine-grained energy modeling, renewable energy integration, and AI/ML-driven dynamic energy-saving optimization. It proposes a novel end-to-end energy-aware architecture integrating real-time energy-information monitoring, user-authorized energy management, and network-intelligent decision-making. The work unifies standardization efforts from 3GPP, ITU, and IEEE, and establishes a multi-dimensional energy-efficiency evaluation framework. Key open problems in the performance–energy trade-off are identified, including energy-information exposure mechanisms, privacy-preserving energy-coordinated scheduling, and cross-layer energy-efficiency optimization. The study provides theoretical foundations and technical pathways toward sustainable 6G networks.

📝 Abstract
6th Generation (6G) mobile networks are envisioned to support several new capabilities and data-centric applications for unprecedented number of users, potentially raising significant energy efficiency and sustainability concerns. This brings focus on sustainability as one of the key objectives in the their design. To move towards sustainable solution, research and standardization community is focusing on several key issues like energy information monitoring and exposure, use of renewable energy, and use of Artificial Intelligence/Machine Learning (AI/ML) for improving the energy efficiency in 6G networks. The goal is to build energy-aware solutions that takes into account the energy information resulting in energy efficient networks. Design of energy-aware 6G networks brings in new challenges like increased overheads in gathering and exposing of energy related information, and the associated user consent management. The aim of this paper is to provide a comprehensive survey of methods used for design of energy efficient 6G networks, like energy harvesting, energy models and parameters, classification of energy-aware services, and AI/ML-based solutions. The survey also includes few use cases that demonstrate the benefits of incorporating energy awareness into network decisions. Several ongoing standardization efforts in 3GPP, ITU, and IEEE are included to provide insights into the ongoing work and highlight the opportunities for new contributions. We conclude this survey with open research problems and challenges that can be explored to make energy-aware design feasible and ensure optimality regarding performance and energy goals for 6G networks.
