An embodiment of the present invention relates to the technical field of communications and discloses a data transmission method and device applicable to a cooperative network of macro and micro base stations. The method comprises: respectively establishing, by a node, a connection with a macro base station and a small base station, wherein, the node, the macro base station and the small base station are in the same access network, and the connection is an X2 connection or a self-defined logical connection; scheduling, by the node, cooperative data, the cooperative data being the data the macro base station and the small base station cooperatively transmitted for a user equipment. By increasing nodes deployed in the access network and using the nodes to schedule the cooperative data in the macro/micro cooperation process, the present invention addresses a problem in the related art in which a long transmission time delay between the macro base station and the small base station under a transmission mode of the macro/micro cooperation affects the performance of the macro/micro cooperation, so as to shorten a transmission time delay between the macro base station and the small base station, improving the performance of the macro/micro cooperation. |
