Embodiments of the present invention provide a synchronization signal carrying method and an apparatus. The synchronization signal carrying method in the present invention includes: determining, by first user equipment, a priority parameter of a synchronization signal; determining, by the first user equipment according to the priority parameter, a resource for carrying the synchronization signal, where a configuration of the resource indicates the priority parameter; and sending, by the first user equipment, the synchronization signal to second user equipment by using the resource, so that the second user equipment determines a synchronization signal for the second user equipment. The embodiments of the present invention enable a more flexible synchronization signal determining manner in a D2D communications system.
