[0002] The power amplifier is a very important part of the base station. In the existing communication system architecture, the power amplifier cannot sense the changes in the traffic volume of the transmitted signal. When working under a constant power supply voltage, the power amplifier efficiency is low in low-load scenarios, and there is a large amount of power loss, resulting in high overall power consumption of the base station system under low load or normal dynamic load scenarios.

By providing an appropriate voltage to the power amplifier, power loss can be reduced to reduce the cost of communication transmission, thereby achieving the purpose of green energy saving.

[0066] In one embodiment, after the target voltage is determined, the target voltage is sent to the power module, the power module generates the target voltage, and gives the target voltage to the power amplifier, so that the power amplifier transmits the signal to be transmitted under the power supply of the target voltage. By providing the power amplifier with an appropriate voltage, the power loss can be reduced, so as to reduce the cost of communication transmission, thereby achieving the purpose of green energy saving.
