5G Energy Performance Design Principles

High energy performance targeting reduced network energy consumption is a critical requirement of 5G. It enables reduced total cost of ownership, facilitates the extension of network connectivity to remote areas, and provides network access in a sustainable and more resource-efficient way. Key technologies to achieve this include ultra-lean design, advanced beamforming techniques, and separation of user-data and system-control planes on the radio interface, as well as virtualized network functionality and cloud technologies. This paper also defines two design principles on which 5G systems with high energy performance should be built.
