A method of more efficiently operating a multiphase direct current (DC) voltage converter configured to provide DC power to a radio, the method comprising:
- synchronizing time, kept by the multiphase DC voltage converter, with a network comprising the radio;
- determining with a model, or receiving, at least one indicium of DC power consumption of the radio for a time period in a future;
- determining, for the time period, at least one of (a) a first number of at least one phase of the multiphase DC voltage converter to enable, and (b) a second number of at least one phase of the multiphase DC voltage converter to disable;
- and
- at least one of (a) enabling the first number of the at least one phase at one of:
- (i) a first time epoch before a commencement of the time period and (ii) at a commencement of the time period, and (b) disabling the second number of the at least one phase at one of:
- (x) a second time epoch after the commencement of the time period and (y) at the commencement of the time period;
- wherein determining with the model the at least one indicium of DC power consumption comprises:
- receiving (a) a number of resource elements to be transmitted by the radio at the time period, and (b) the time period;
- and
- determining the at least one indicium of DC radio power consumption for the time period by transforming, with the model, the received number of resource elements into the at least one indicium of DC radio power consumption.

- wherein determining with the model the at least one indicium of DC power consumption comprises:
- receiving (a) a number of resource elements to be transmitted by the radio at the time period, and (b) the time period;
- and
- determining the at least one indicium of DC radio power consumption for the time period by transforming, with the model, the received number of resource elements into the at least one indicium of DC radio power consumption.
