FREQUENCY COMPENSATION DEVICE AND FREQUENCY COMPENSATION METHOD THEREOF |
摘要 |
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. |

1. A frequency compensation device, applicable to 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; andcalculating 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; andsending a second signal to the first BS at the second transmitting frequency which is compensated. |
