Abstract
A device and a device synchronization method in D2D communication, so as to implement synchronization between devices in D2D communication is provided. The device includes: a receiving unit, configured to receive first D2D synchronization information sent by a first device in D2D communication, where the first D2D synchronization information includes a synchronization source identifier and a forwarding hop count. The device also includes a processing unit, configured to synchronize with a synchronization source corresponding to the synchronization source identifier in the first D2D synchronization information, and update the forwarding hop count in the first D2D synchronization information when determining that the forwarding hop count in the first D2D synchronization information is less than a set threshold, so as to obtain second D2D synchronization information. The device also includes a sending unit, configured to send the second D2D synchronization information.
