This TR is for investigating deployment aspects that relate to energy efficiency, including potential
system enhancements that support energy efficient deployments. System enhancements may be anticipated in the area
of functions that have major influence on deployment like functions that support pools of CN nodes or functions that enable multiple CN nodes to serve the same or overlapping areas.
The initial focus is on PS domain. This study should avoid any overlap with the work by RAN/CT/SA5 by taking into account the work that has been and is going on in these WGs. Proposals have to be well justified to be considered in this document.
