Disclosed are a D2D communication method, a user equipment, and a base station, for use in avoiding a resource allocation conflict of a D2D distributed network. The method in an embodiment of the present invention comprises: in a process of establishing a D2D multi-hop connection, a UE first acquires time-frequency resources for channel measurement; the UE measures a channel where in the time-frequency resources are located to determine whether the channel is idle; if the channel is idle, the UE pre-occupies the channel; and when a time point for establishing a D2D connection arrives, the UE establishes the D2D connection by means of the channel. By pre-occupying an idle channel, the UE prevents another UE to occupy the channel, thereby avoiding a resource allocation conflict in a D2D multi-hop data transmission scenario, and preventing interference between links. |
