E2E 5GS Sustainability Enhancement: A Standardization Viewpoint

Driven by rising energy costs and growing environmental concerns, sustainability-aware network operations in 5G-Advanced research and standardization have gained increased attention. In this paper, we introduce a set of potential solutions with focus on energy efficiency and carbon emission reduction. These solutions are proposed to be studied and included in the 5G 3GPP standard. In particular, we focus on solutions aimed at the cross-domain energy optimization (encompassing Core Network (CN), Radio Access Network (RAN) and Edge), inter-operator optimizations and the service specific implications of these optimizations (e.g., energy-aware charging and analytics).
