Enhanced energy efficiency information for network energy saving

An apparatus, comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to at least perform receiving, from a neighboring radio access network node or an operations and maintenance function, indication of at least one of energy cost for extra load or energy saving for removed load based on cell capability of the neighboring radio access network node;
• determining to perform onloading of cell traffic to or offloading of cell traffic from the neighboring radio access network, based on the indication of the at least one of the energy cost for extra load or the energy saving for removed load;
• and
• handling cell traffic based on the determination.

A method, comprising:

• identifying own cell capability comprising at least one of an own cell capability to carry extra load with no extra energy consumption, an own cell capability to carry extra load with extra energy consumption, or an own cell capability to reduce load with an energy saving gain;
• indicating to a neighboring radio access network node or an operations and maintenance function at least one of energy cost for extra load or energy saving for removed load based on the own cell capability;
• and
• receiving onloading of cell traffic or offloading of cell traffic, based on the indication of the at least one of the energy cost for extra load or the energy saving for removed load.
