SYSTEMS AND METHODS FOR PROVIDING VOLTAGE BOOSTING TO A TIME DOMAIN DUPLEXING RADIO
Techniques are provided for diminishing power loss in electrical conductors used to provide electrical power to a radio configured to use time domain duplexing (TDD). Because the TDD radio typically transmits data during a downlink subframe, the TDD radio generally consumes more power, and thus draws more current through the electrical conductors, then during an uplink subframe when the TDD radio is configured to receive. Thus, during the downlink subframe, a DC voltage, output by a DC-DC voltage converter to the electrical conductors, is increased to lessen current drawn by the radio through the electrical conductors. As a result, power loss in the electrical conductors is reduced.
