Abstract
A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE obtains a first timing advance (TA) value of a source BS, and receives a radio resource control (RRC) connection reconfiguration message for a handover from the source BS to a target BS. The UE calculates a receiving time difference between a receiving time of two synchronization signals respectively transmitted by the source BS and the target BS, and calculates a reference time difference according to first reference time information of the source BS and second reference time information of the target BS. The UE calculates a second TA value of the target BS based on the first TA value, the receiving time difference and the reference time difference.
