Disclosed are a method and an apparatus for transmitting D2D signals, wherein the method comprises: detecting a synchronization signal and/or a D2D signal, and determining a synchronization reference for sending or receiving other D2D signals based on the synchronization signal and/or the D2D signal; based on information carried in the detected synchronization signal and/or the D2D signal, determining a D2D resource configuration; and based on the determined synchronization reference for sending or receiving the other D2D signals and the determined D2D resource configuration, determining a resource position used for transmitting D2D signals, and sending or receiving the other D2D signals in the resource position. By enabling a UE to learn the D2D resource configuration based on the synchronization signal and/or the D2D signal, the present application prevents the UE from always using fixed resources when transmitting D2D signals, thus reducing mutual interference and improving transmission efficiency and quality.
