Abstract
Embodiments of this application disclose a data transmission method that includes sending, by a base station, first scheduling information to first UE. The first scheduling information instructs the first UE to send data to second UE based on the first scheduling information. The method includes receiving, by the base station, first feedback information sent by the first UE. The method includes sending, by the base station, second scheduling information to the first UE if the first feedback information indicates that the second UE fails to receive the data. Embodiments of this application further provide a base station, UE, and a data transmission system. In embodiments of this application, the first UE may perceive a data receiving status of the second UE by receiving the first feedback information, so that a corresponding resource can be assigned again for data retransmission.
