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.

Abstract: Embodiments of the present disclosure provide a method, device, radio network controller and chip for improving network quality. A signal of a user in a serving cell, detected by the same-frequency cell adjacent to the serving cell, is combined with a signal detected by the serving cell using a MCJD technology, so as to improve the signal quality of the user in the serving cell. The method of the present disclosure comprises: obtaining a first signal which belongs to a user terminal of a first cell and is detected by a base station of at least one second cell; combining the first signal with a second signal of the user terminal detected by a base station of the first cell to obtain a third signal; sending the third signal to a radio network controller. Therefore, the signal quality of the user in the first cell can be improved.

Abstract: A coordinated scheduling method and a related apparatus are disclosed. The embodiments of this application may be applied to multi-frequency ultra-dense networking. The method includes: A base station first determines one or more frequencies corresponding to cells at a capacity layer and one or more frequencies corresponding to cells at a coverage layer. Some cells at the coverage layer are obtained by combining at least two cells having co-channel interference, and cells at the capacity layer are all cells that are not combined. In addition, the base station further obtains network information of the first terminal on at least one carrier set, and optimizes the current network based on the network information.
