Abstract:
Exemplary embodiments provide a method and apparatus for transmitting a synchronization signal for Device-to-Device (D2D) communication in a wireless communication system. With respect to a D2D synchronization source to transmit a synchronization signal for D2D communication, the method includes: generating a D2D Synchronization Signal (D2DSS); and transmitting, by a synchronization source, the D2DSS to a D2D reception (Rx) UE, wherein the D2DSS includes a Primary D2D Synchronization Signal (PD2DSS) generated based on information associated with the synchronization source.

Claim (Index 1):
A first wireless communication device comprising:\n a receiver to receive a synchronization signal transmitted from a synchronization source; a processor to determine a root index based on the received synchronization signal, and to determine a synchronization timing reference based on the root index; and a transmitter to transmit, based on the determined synchronization timing reference, a synchronization signal for a direct communication between the first wireless communication device and a second wireless communication device, wherein determining, by the processor, the synchronization timing reference comprises:\n based on the root index, determining a category of the synchronization source; \n prioritizing the synchronization source based on determining whether the synchronization source is an evolved NodeB (eNodeB), a wireless communication device synchronized with an eNodeB, or a wireless communication device having a synchronization timing reference independent from an eNodeB; \n determining whether the synchronization source is a wireless communication device located in a coverage of an eNodeB or a wireless communication device located out of a coverage of an eNodeB, among wireless communication devices synchronized with an eNodeB; \n prioritizing the synchronization source further based on determining whether the synchronization source is a wireless communication device located in a coverage of an eNodeB or a wireless communication device located out of a coverage of an eNodeB; and \n determining the synchronization timing reference based on the prioritization.
