Abstract

The present invention provides a method for transmitting a radio frequency (RF) signal and a base station device. The method includes: controlling energy of a first RF input signal of a power amplifier (PA), transmitting a first RF output signal, and coupling part of the first RF output signal and feeding it back to a predistortion system, so as to control the energy increase of a second RF input signal inputted to the PA according to a preset energy increment. The method can realize adjustment for the interModulation Distortion (IMD) component in the RF output signal outputted from the PA in an initial phase (that is a startup phase), thereby improving linearity of the PA in the initial phase.
