Summary

Supplement 36 to the ITU-T L-series Recommendations analyses the energy efficiency issues for future 5G systems. 5G systems are the object of standardization in 3GPP and ITU and is planned to be available from 2018 in various countries. The focus of this Supplement is on methods and metrics to measure energy efficiency in 5G systems, with a consideration of the degree of the stability of the systems known so far and the experience of the legacy systems as well as related measurement procedures for evaluating future standardization evolutions.
