The embodiment of the invention discloses a power control method and device, belonging to the technical field of communication, the method comprises: a plurality of channels to obtain the initial power amplifier corresponding to the initial transmit power; when the plurality of channel transmit power and the power amplifier exceeds the maximum transmit power, transmission power is reduced the priority of multiple channels in the lowest at least one channel; if a channel to reduce the transmission power of other channel transmit power and a plurality of channels in the difference is greater than the preset threshold A, or if the channel in the lower transmission power channel transmission power and multiple channel spectral density difference B is larger than the preset threshold, it will close the channel. By adopting the technical scheme, the performance loss caused by the non-linearity of the power amplifier can be reduced, and the data transmission performance can be improved.
