The invention provides an energy-saving method and device for a
radio frequency unit, equipment and a medium, and the method comprises the steps that the
radio frequency unit detects an IQ time-domain
signal of each
radio frequency channel in real time, and detects a zero sequence with the amplitude of the IQ time-domain
signal being zero; and when the zero sequence is detected, comparing the
duration time of the zero sequence with a preset time threshold value, and when the
duration time exceeds the preset time threshold value, controlling the radio frequency power
amplifier switch of the corresponding radio frequency channel to be in a turn-off state through the radio
frequency unit. The zero sequence and the duration of the
baseband IQ
time domain signal corresponding to each path of radio frequency power
amplifier are detected, and when the duration of the zero sequence exceeds the preset threshold duration, the radio frequency power
amplifier switch is controlled to be in the turn-off state through the radio
frequency unit, so that the method does not depend on a
base station topological structure, and the reliability of the radio frequency power amplifier switch is improved. Or the purpose of reducing the
energy consumption of the radio
frequency unit of the
base station can be quickly realized at low cost without depending on the
function optimization or control of the BBU side or the
baseband processor.
