  • Downlink transmission method in heterogeneous network, control device, base station and heterogeneous system
    Patent number: 9949287
    Abstract: The present invention provides a downlink transmission method in a heterogeneous network, a control device, a base station, and a heterogeneous system. The method includes: when one or more micro base stations need to schedule an edge user in an almost blank subframe ABS, determining, by a control device, at least one micro base station that needs to transmit information to the edge user jointly with a macro base station from the one or more micro base stations; and instructing, by the control device, the macro base station and the micro base station that needs to transmit information to the edge user jointly with the macro base station, to transmit information to the edge user in the ABS. Embodiments of the present invention can avoid a resource waste of the macro base station, and enhance system performance.
