Title: END-TO-END D2D COMMUNICATION METHOD AND D2D COMMUNICATION DEVICE
Abstract:
The present invention provides an end-to-end D2D communication method and a D2D communication device. The method comprises: according to a first time slot for sending D2D transmission signaling to a receiving end and a synchronization transmission relationship between the D2D transmission signaling and D2D data, determining a second time slot for transmitting the D2D data, the second time slot being after the first time slot; according to the second time slot, determining a third time slot for sending uplink control information in cellular communication, the uplink control information being used for indicating an uplink radio resource of a cellular UE in the second time slot, and the third time slot being before the second time slot; demodulating the uplink control information in the third time slot to obtain the uplink radio resource of the cellular UE in the second time slot; multiplexing the uplink radio resource of the cellular UE in the second time slot, and performing D2D communication with the receiving end. In an embodiment of the present invention, a sending end and the receiving end perform D2D communication through space division multiplexing of the uplink radio resource of the cellular UE in cellular communication, control by a base station is not demanded, and the transmission efficiency and the utilization rate of the radio resource can be improved.
