Claim:
1. A device-to-device (D2D) communication method, comprising: determining, by a D2D transmitter, a second time slot for transmitting D2D data according to a first time slot for transmitting D2D signaling to a D2D receiver and a synchronous transmission relationship between the D2D signaling and the D2D data; determining, by the D2D transmitter, a third time slot for transmitting uplink control information in cellular communication according to the second time slot, wherein the uplink control information is used for indicating an uplink radio resource and timing advance (TA) in the second time slot of a cellular UE; demodulating, by the D2D transmitter, the uplink control information in the third time slot to acquire the uplink radio resource in the second time slot of the cellular UE; selecting a first cellular UE, from the cellular UEs, having minimal interference to the D2D transmitter by selecting the first cellular UE, from the cellular UEs, so as to maximize the difference between the TA of the first cellular UE, and a TA of the D2D transmitter; and multiplexing the uplink radio resource in the second time slot of the first cellular UE to perform D2D communication with the D2D receiver.
