END-TO-END D2D COMMUNICATION METHOD AND D2D COMMUNICATION DEVICE

摘要

The present invention provides a D2D communication method and a D2D communication device. The method includes: determining 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, the second time slot being after the first time slot; determining a third time slot for transmitting uplink control information in cellular communication according to the second time slot, the uplink control information being used for indicating an uplink radio resource in the second time slot of a cellular user equipment UE, and the third time slot being before the second time slot; demodulating the uplink control information in the third time slot to acquire the uplink radio resource in the second time slot of the cellular UE; multiplexing the uplink radio resource in the second time slot of the cellular UE to perform D2D communication with the D2D receiver. In the embodiments of the present invention, the D2D transmitter and the D2D receiver perform D2D communication by space division multiplexing the uplink radio resource of the cellular UE in the cellular communication, without control of a base station, so as to improve transmission efficiency and radio resource utilization.
