Abstract:
1. A frequency compensation device for a user equipment (UE) communicating with a first base station (BS), comprising: a receiving module, having an offset detection unit, and the offset detection unit is configured to perform steps of: receiving at least one first signal from the first BS at a first receiving frequency; reading a first transmitting frequency at which the first BS transmits the at least one first signal; and calculating a difference between the first transmitting frequency and the first receiving frequency, and using the difference as a frequency difference; and a transmitting module configured to perform steps of: obtaining a BS parameter corresponding to the first BS; calculating a frequency compensation value according to the BS parameter; compensating a second transmitting frequency according to the frequency compensation value corresponding to the first BS; and sending a second signal to the first BS at the second transmitting frequency which is compensated.
