Frequency compensation device and frequency compensation method thereof

Abstract

A frequency compensation device, applicable to a user equipment (UE) communicating with a first base station (BS), includes a receiving module and a transmitting module. The receiving module has an offset detection unit for performing following steps. A first signal from the first BS at a first receiving frequency is received. A first transmitting frequency where the first BS transmits the at least one first signal is read. A difference between the first transmitting frequency and the first receiving frequency is calculated and used as a frequency difference. The transmitting module is for performing following steps. A BS parameter corresponding to the first BS is obtained. A frequency compensation value according to the BS parameter is calculated. A second transmitting frequency according to the frequency compensation value corresponding to the first BS is compensated. A second signal to the first BS at the compensated second transmitting frequency is sent.
