Evaluation of the energy consumption of dissimilar component, node, and network design options requires adequate performance metrics and such energy metrics are discussed in this report. Among the components a special focus is given to metrics suitable to assess the energy consumption of the transceiver system and the baseband, since it is these two units that dominate the energy consumption of a typical base station. In network level studies it is essential that both the quality of service as well as the energy consumption are properly measured. Finally, a utility based comparison framework is derived, which facilitates structured relative comparisons of different network solutions in which low energy consumption and high quality of service are conflicting requirements.
