Abstract

The present disclosure provides a device to device (D2D) synchronization method that is applicable to a user equipment and a user equipment (UE) using the same method. In one of the exemplary embodiments, the D2D synchronization method includes receiving detected signals from a receiver, obtaining from the detected signals a first signal having a first timing information and a second signal having a second timing information, determining whether to forward the first timing information or the second timing information based on an upper bound power restriction of the first signal and the second signal and a power difference between the first signal and the second signal, and determining whether to transmit a third timing information that is inherent of the UE based on whether the first signal and the second signal are below power thresholds.
