Abstract:
1. A power control method, comprising: obtaining a current main carrier power of a main carrier and a current supplementary carrier power of a supplementary carrier; selecting a reference carrier from the main carrier and the supplementary carrier; calculating a difference between the main carrier power and the supplementary carrier power to obtain a first difference; determining a quantized value corresponding to the first difference by querying a preset configuration parameter table according to the first difference, wherein the configuration parameter table comprises a mapping relationship between the first difference and a second difference, the second difference is a difference between a preset total power of the main carrier and the supplementary carrier and a greater carrier power in the main carrier power and the supplementary carrier power, and the quantized value is a fixed value obtained by quantization of the second difference corresponding to the first difference; and determining, according to the power of the reference carrier and the quantized value, a total transmit power for transmitting the main carrier and the supplementary carrier.
