The present document identifies and studies the key issues and the potential solutions in defining Energy Efficiency Key Performance Indicators and the Energy Efficiency optimization operations in existing and future 3GPP networks.
The study includes:
identifying the 3GPP system wide high-level goals and feasible tasks including the definition of system-wide energy efficiency KPIs where it is applicable to systematically address energy efficiency aspects more effectively;
investigating feasible common approaches and methodology including the assessment of the relevance and the applicability of existing energy efficiency definitions and the related work to address and improve 3GPP system-wide energy efficiency.
Recommendations are provided applicable to EPS (taking into account backward compatibility to legacy UEs), and to 5G systems.
