摘要:
The present disclosure relates to a Doppler shift compensation scheme applicable in a high mobility communication system. In some examples, a Doppler shift compensation apparatus may include an angle measuring unit configured to measure Angle Of Arrival (AOA) information of a User Equipment (UE); a velocity calculating unit configured to calculate a velocity information of the UE based on the measured AOA information; a frequency shift estimating unit configured to estimate Doppler shift of the UE based on the measured AOA information and the calculated velocity of the UE; a frequency shift compensation triggering unit configured to trigger Doppler frequency shift compensation based on the estimated Doppler shift of the UE; and a frequency shift compensating unit configured to perform the Doppler frequency shift compensation based on a trigger instruction from the frequency shift compensation triggering unit. Doppler shift compensation methods are also described in some other examples of the present disclosure.
