An inter-UE priority scheduling method is disclosed, where the method includes: generating an enhanced buffer status report BSR according to buffered data information of multiple benefitted user equipments B-UEs, and reporting the enhanced BSR to a base station eNB, where the enhanced BSR carries buffer data status information of the multiple B-UEs, so that the eNB determines, according to the buffer data status information, priorities of performing data transmission on the multiple B-UEs; receiving uplink scheduling information delivered by the eNB, where the uplink scheduling information carries the priorities of performing data transmission on the multiple B-UEs; and encapsulating some or all of currently buffered data of the multiple B-UEs into one MAC PDU according to the priorities of performing data transmission on the multiple B-UEs, and transmitting the MAC PDU to the eNB.
