Energy Performance of 6G Radio Access Networks

This white paper discusses the energy performance of 6G radio access networks, emphasizing the importance of minimizing energy consumption while meeting performance requirements such as user throughput, capacity, and latency. It outlines the challenges faced by the telecommunications industry in reducing energy consumption, particularly in the radio access network (RAN), which accounts for a significant portion of energy usage. The paper highlights advancements made in energy performance with the introduction of lean design principles in 5G NR and proposes further enhancements for 6G. Key areas for standardization are presented to facilitate increased energy savings in 6G compared to 5G NR. The document also examines traffic characteristics and the need for energy-efficient network designs that can adapt to varying load conditions. By addressing the energy costs associated with cellular networks, particularly during idle modes, the paper aims to provide a framework for developing more sustainable 6G technologies.
