Abstract:
This application discloses a frequency compensation method and apparatus, to improve performance of frequency compensation. The method includes: determining a change rate of a Doppler frequency shift value based on a weighted change rate of a change rate of a timing advance TA, determining the Doppler frequency shift value based on the change rate of the Doppler frequency shift value, and performing frequency compensation based on the determined Doppler frequency shift value; or determining a frequency offset value based on the Doppler frequency shift value with reference to pre-compensation and based on a reference signal, to further determine a frequency offset value, and performing frequency compensation based on the frequency offset value.
