5 . The method of claim 1 , wherein the request comprises at least one of:

an indication to report the energy or power consumption status for at least one of a specified: bit, cell, beam, network node, network slice, channel, antenna site, transmitter, receiver, bearer type, or quality of service (QoS) parameter,

an indication to report a load corresponding to a reported energy or power consumption metric,

an indication for the second base station to measure and/or estimate the energy or power consumption status of the second base station for one or more load levels,

an indication of a time interval corresponding to a measurement for reporting the energy or power consumption status of the second base station,

an indication for the second base station to estimate and report the energy or power consumption status of the second base station as a result of one or more proposed actions,

an indication for the second base station to start, pause, resume, or stop reporting of the energy or power consumption status of the second base station.

6 . The method of claim 5 , wherein a proposed action of the one or more proposed actions comprises at least one of:

the first base station offloading an amount of network traffic to the second base station,

the second base station modifying a coverage of a radio cell currently being served by the second base station, or

the first base station modifying a coverage of a radio cell currently being served by the first base station.

7 . The method of claim 1 ,

wherein the first message is a resource status request message and the resource status request message comprises an indication to report the energy or power consumption status of the second base station, and

wherein the second message is a resource status update message, and the resource status update message comprising an energy or power consumption status metric.

8 . The method of claim 1 , wherein the first message is a first configuration transfer message and the second message is a second configuration transfer message.

9 . The method of claim 1 , further comprising:

the first base station determining, based on the response to the first message, an action that improves energy efficiency of the first base station and/or the second base station.

10 . The method of claim 9 , further comprising:

the first base station performing the action or transmitting a message to initiate the action.

11 . The method of claim 10 , further comprising:

the first base station generating a third message, the third message comprising a second request relating to an energy or power consumption status of the second base station;

the first base station transmitting the third message to the second base station;

the first base station receiving a fourth message transmitted by the second base station, the fourth message comprising a response to the third message;

comparing the response in the fourth message to the response in the second message; and

updating the machine learning model based on the comparison.

12 . The method of claim 9 , the method further comprising:

the first base station providing, to a machine learning model, input based on the response to the first message; and

the first base station obtaining an output generated by the machine learning model, the output comprising an indication of the action that improves energy efficiency of the first base station and/or the second base station.

13 . The method of claim 12 , wherein the machine learning model is implemented in the first base station.

14 . The method of claim 12 , wherein the machine learning model is implemented in a central node, and wherein:

the providing comprises the first base station transmitting the input towards the central node; and

the obtaining comprises receiving the output transmitted by the central node.

15 . The method of claim 9 , wherein the action comprises one or more of:

offloading one or more user equipment from the first base station or the second base station,

turning on or turning off cells, or

adjusting a configuration of the first base station or the second base station.

16 . The method of claim 9 , wherein the determining further comprises determining that the action satisfies a quality-of-service requirement.

17 . The method of claim 1 ,

wherein the transmitting the first message towards the second base station comprises transmitting the first message to a control node in communication with the second base station, and

wherein the receiving the second message comprises receiving the second message from the control node.

18 . A first base station in a radio access network comprising a processor coupled to a non-transitory computer readable medium, wherein the processor is configured to:

generate a first message, the first message comprising a request relating to an energy or power consumption status of a second base station;

transmit the first message towards the second base station; and

receive a second message transmitted by the second base station, the second message comprising a response to the first message, wherein the response comprises a measured energy consumption metric.

19 . A method performed by a second base station for reporting an energy metric to a first base station, the method comprising:

the second base station receiving a first message transmitted by the first base station, the first message comprising a request relating to an energy or power consumption status of the second base station; and

the second base station transmitting a second message towards the first base station, the second message comprising a response to the first message, wherein the response comprises a measured energy consumption metric.
