The present invention relates to a power control method and apparatus, where the method includes: respectively determining, by a base station, error vector magnitude EVM indicator adjustment parameters of n terminals according to terminal types of the n terminals that are currently scheduled; processing, according to the EVM indicator adjustment parameters of the n terminals, to-be-transmitted signals of the n terminals to obtain an output signal, and determining a change of total power of the output signal relative to the to-be-transmitted signals; and dynamically controlling a supply voltage of a power amplifier according to the change of the total power of the output signal relative to the to-be-transmitted signals. According to the power control method and apparatus provided in embodiments of the present invention, different processing is performed on signals of different terminals, so that a balance among total power, EVM, and power amplifier efficiency in an OFDM system is considered, and system performance of the OFDM system is improved. |
