Abstract: An electronic device is provided. The electronic device includes a communication circuit, a memory, and a processor operatively connected to the communication circuit and the memory, wherein the processor may be configured to detect an event for transmission of a synchronization signal in a device-to-device (D2D) mode, start a first timer stored in the memory, transmit a synchronization signal at a specified first timing during a first time period during which the first timer operates, and attempt to receive a synchronization signal at a specified second timing during the first time period, sense that a synchronization signal and a valid data packet have not been received by the time that the first timer expires, and attempt to receive a synchronization signal at a timing corresponding to the designated first timing during the second time period after the first timer has expired.
