A computer software module apparatus, a circuitry apparatus, an apparatus and a method for an improved monitoring of energy efficiency of a radio unit

A radio access network (RAN) baseband unit comprising:

• a controller, wherein the controller is configured to:
• receive a plurality of power measurements for one or more RAN radio units for a configuration utilized by the one or more RAN radio units;
• aggregate the plurality of power measurements into an aggregated power measurement report;
• and
• transmit the aggregated power measurement report to a RAN radio control unit.

A radio access network (RAN) radio unit comprising:

• a controller, wherein the controller is configured to:
• measure a plurality of power characteristics of the RAN radio unit during a time period;
• and
• transmit the plurality of power characteristics of the RAN radio unit as a measured power characteristics to a RAN baseband unit.

A method comprising:

• storing one or more configurations along with expected power characteristics for the one or more configurations;
• receiving a power measurement report indicating one configuration out of the one or more configurations and a corresponding measured power characteristics for a radio access network (RAN) radio unit;
• determining whether the measured power characteristics corresponds to the expected power characteristics of the indicated configuration, and if so
• verifying the configuration;
• and if not so
• issuing a warning.
