Claim of US Patent No. 10,117,277

1. A method for transmitting a Device-to-Device (D2D) signal by a first user equipment (UE) for D2D communication in a wireless communication system, the method comprising:selecting a resource set among a plurality of resource sets configured for the D2D communication; and
transmitting the D2D signal using at least one radio resource corresponding to the resource set,
wherein a reference cell for synchronization for transmitting the D2D signal is determined, among cells associated with the plurality of resource sets, based on whether the first UE is in a Radio Resource Control (RRC) IDLE state.
