Abstract: The present disclosure provides a synchronization processing method and a UE, so as to improve synchronization accuracy between the UE outside a coverage area and a UE within the coverage area. The synchronization processing method includes steps of: determining, by the UE outside the coverage area, a synchronization resource starting position of the UE within the coverage area after the UE outside the coverage area has detected a synchronization signal from the UE within the coverage area; determining, by the UE outside the coverage area, its own synchronization resource starting position in accordance with the synchronization resource starting position of the UE within the coverage area; and transmitting, by the UE outside the coverage area, a synchronization signal in accordance with its own synchronization resource starting position and its own synchronization resource period. According to the present disclosure, upon receiving the synchronization signal from the UE within the coverage area, the UE outside the coverage area transmits the synchronization signal continuously in accordance with the received synchronization signal. In addition, according to the present disclosure, it is able to improve the synchronization accuracy between the UE outside the coverage area and the UE within the coverage area.
