The processor 1401 is configured to if the quantity c of conflicts of the first UE is less than the threshold C0, the conflict time w of the first UE is less than the threshold W0, or the service priority Q of the first UE or the priority of the UE is lower than the threshold Q0, the processor 1401 determines preset duration T according to the preset parameter, and the transmitter 1403 randomly determines the Z resources from the S resources at an interval of the preset duration T. The transmitter 1403 is configured to send the data to the at least one second UE on the Z resources.
The transmitter 1403 is further configured to if the quantity c of conflicts of the first UE is not less than the threshold C0, the conflict time w of the first UE is not less than the threshold W0, or the service priority Q of the first UE or the priority of the UE is not lower than the threshold Q0, send the data to the at least one second UE on the Z resources.
