Systems and methods for providing voltage boosting to a time domain duplexing radio

A non-transitory computer readable medium storing a program causing at least one processor to execute a process for diminishing power dissipation in electrical conductors providing direct current (DC) electrical power to a time division duplexing (TDD) radio, the process comprising:

• synchronizing timing of a DC-DC voltage converter with a time source external to the DC-DC voltage converter;
• receiving, from a component of a radio access network (RAN) external to the DC-DC voltage converter, (a) a TDD frame configuration or an indication of the TDD frame configuration and (b) a reference time;
• wherein the reference time is a time when a reference TDD frame commences in a past, a present, or a future, or another time from which such time can be derived;
• using at least one of the TDD frame configuration and the reference time, determining a start time and an end time of each downlink subframe in a TDD frame;
• using the start time of each downlink subframe in the TDD frame, during each downlink subframe, of the TDD frame, of the TDD radio, causing an increase of a DC voltage output by the DC-DC voltage converter;
• and
• using the end time of each downlink subframe in the TDD frame, on or after cessation of each downlink subframe in the TDD frame, causing a decrease of the DC voltage output by the DC-DC voltage converter.

An apparatus for diminishing power dissipation in electrical conductors providing direct current (DC) electrical power to a time division duplexing (TDD) radio, the apparatus comprising:

• DC-DC voltage converter circuitry configured to be electrically coupled, through the electrical conductors, to a DC power input of the TDD radio;
• and
• processing circuitry communicatively coupled to the DC-DC voltage converter circuitry, configured to be communicatively coupled to a time source external to the apparatus, and configured to:
• synchronize timing of a DC-DC voltage converter with the time source external to the DC-DC voltage converter;
• receive, from a component of a radio access network (RAN) external to the DC-DC voltage converter, (a) a TDD frame configuration or an indication of the TDD frame configuration and (b) a reference time;
• wherein the reference time is a time when a reference TDD frame commences in a past, a present, or a future, or another time from which such time can be derived;
• using at least one of the TDD frame configuration and the reference time, determine a start time and an end time of each downlink subframe in a TDD frame;
• using the start time of each downlink subframe in the TDD frame, during each downlink subframe, of the TDD frame, of the TDD radio, cause an increase of a DC voltage output by the DC-DC voltage converter circuitry;
• and
• using the end time of each downlink subframe in the TDD frame, on or after cessation of each downlink subframe in the TDD frame, cause a decrease of the DC voltage output by the DC-DC voltage converter circuitry.
