Abstract

Lately, energy efficiency (EE) in mobile communications is receiving growing attention as its increasing energy consumption raises concern over climate effects. As a stepping stone to improve the situation, we provide some analytical tools for optimising the EE of a base station through power control, focusing on elastic traffic in the downlink scenario. Under certain assumptions, the problem is formulated such that any rate maximisation algorithm can be incorporated to achieve the optimum EE. Furthermore, when formulated as a function of one sum power variable, optimality is illustrated graphically and Pareto optimality is discussed. Finally, an EE function for a base station in a cellular network is proposed that captures essential factors of power consumption.
