Abstract: The present invention provides a method and apparatus for supporting device-to-device (D2D) communication in a wireless communication system. The present invention obtains information on time and resources required for signal transmission of corresponding user equipment (UE), estimates transmission time of the signal transmission by using the information on time and resources, and checks propagation delay by comparing the estimated transmission time with reception time of a signal transmitted from an actual corresponding UE. The present invention compares the checked propagation delay with predetermined reference values for converting to D2D communication and determines whether to perform D2D communication. Also, the determining D2D communication may include determining conversion to D2D communication by taking account of a channel state of a received signal.
