At present, sustainable development is a long-term commitment for all people in the world. This means not only development but also innovation. People should do their best to handle the resource shortage and environment deterioration. Therefore, how to improve the power efficiency and realize the power saving becomes a significant issue.

In the telecom area, most mobile network operators aim at decreasing the power consumption without too much impact on their network. In this case, the greenhouse emissions are reduced, while the OPEX of operators is saved.

Thus, the power efficiency in the infrastructure and terminal becomes an essential part of the cost-related requirements in network, and there is a strong need to investigate possible network energy saving solutions.

The present document is the technical report for the study item Study on Energy Saving Enhancement for E-UTRAN [RP-122035] which was approved at TSG RAN#58. The objectives of this study item are to identify potential solutions for energy saving scenarios for the LTE coverage layer scenario and the overlaid scenario and to perform their initial evaluation so that a subset of them can be used as the basis for further investigation and standardization.
