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.

Abstract: An electronic device is provided. The electronic device includes a wireless communication circuit, a memory for storing an EARFCN list, and a processor configured to identify whether the electronic device is in a designated mode, when the electronic device is in the designated mode, perform a scan sequentially on at least some channels from among a plurality of channels included in the EARFCN list, when a first channel satisfying a first condition is identified as a result of the scan, identify whether the first channel corresponds to a second condition by decoding a system information block (SIB) or a master information block (MIB) received through the first channel, when the first channel satisfies the second condition, select a cellular network regarding the first channel, and when the first channel does not satisfy the second condition, stop the scan and perform D2D communication during a designated time.

Abstract: An example electronic device may include a plurality of antennas; and at least one communication processor communicating with a first communication network or a second communication network through the plurality of antennas. The at least one communication processor may be configured to set up a call with an external electronic device through the first communication network, identify information related to call quality in a call connected state with the external electronic device, and perform an operation for reducing a number of antennas for reception among the plurality of antennas based on identifying that the information related to the call quality meets a designated condition.
