The present invention provides a data transmission method, a base station, and a user equipment. The method comprises: a first base station establishing a first packet data convergence protocol (PDCP) entity; the first base station sending first configuration information to a second communication node, and sending second configuration information to a user equipment, so as to establish a second radio bearer between the second communication node and the user equipment; the first base station sending fourth configuration information to the second communication node, so as to establish a third bearer between the first base station and the second communication node; and the first base station using the third bearer and the second radio bearer to transmit at least a part of data in service data between the first base station and the user equipment, wherein during the transmission process of the service data by the first base station, the first PDCP entity of the first base station and a second PDCP entity of the second communication node perform joint processing on at least a part of the data, and the first PDCP entity performs a serial number processing function on the service data. The present invention can improve throughput of a user equipment. |
