Downlink transmission method, control apparatus, base station, and heterogeneous system in heterogeneous network

摘要

The present invention provides a downlink transmission method, control apparatus, base station, and heterogeneous system in a heterogeneous network. When one or more micro base stations need to schedule an edge user in a substantially empty subframe (ABS), a macro unit can select a macro from among the one or more micro base stations. Determining at least one micro base station that needs to transmit information to the edge user in cooperation with a base station, and transmitting the information to the edge user by the ABS by the control device. And instructing the micro base station that needs to transmit information to the edge user in cooperation with the macro base station. According to the embodiments of the present invention, the performance of edge users of a micro base station can be improved, the resource consumption of the macro base station can be avoided, and the system function can be expanded.
