Abstract
Official abstract text for this publication.
The present invention relates to a power control method, including: 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; 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. In the whole process, a power of a previous timeslot does not need to be introduced, therefore, error accumulation can be avoided, thereby reducing a power control error and improving control precision.
