The present document specifies concepts, use cases, requirements and solutions for the energy efficiency assessment and optimization for energy saving of 5G networks.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Candidate cell:
cell which can provide coverage when the original cell goes into energySaving state.
energySaving state:
state in which a cell or network function is powered-down for energy saving purposes.
notEnergySaving state:
state when no energy saving is in progress.
ES activation:
procedure to power down a cell or network function for energy saving purposes.
ES deactivation:
procedure to power up a cell or network function.
ES Probing procedure:
procedure executed by an ES probing capable cell triggered by Cell Activation procedure or ES deactivation procedure.
compensatingForEnergySaving state:
in an off-peak traffic situation, a cell is remaining powered on, e.g. taking over the coverage areas of neighbor cell in energySaving state.
ES compensation:
the procedure to change a cell's configuration to remain powered on for compensating energy saving activation on other cells, e.g. by increasing a cell's coverage area. As a result, the cell is in compensatingForEnergySaving state.
Energy Efficiency (EE):
ratio between performance and energy consumption.
Energy Consumption (EC): integral of power consumption over time.
For the purposes of the present document, the abbreviations given in TR 21.905 and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905.
