Abstract

The invention provides a downlink transmitting method, and a control device, a base station and a heterogeneous system in a heterogeneous network. The method comprises the following steps of determining at least one of one or more micro-stations, which needs to be joined with a macro-station to transmit information to edge users through a control device when one or more micro-stations need to schedule the edge users on a quiet subframe ABS; and adopting the control device to instruct the macro-station and the micro-station needing to be joined with the macro-station to collectively transmit the information to the edge user to transmit the information to the edge user on the ABS. By adopting the downlink transmitting method, the performance of the micro-station edge user can be enhanced, the resource waste of the macro-station can be overcome, and the system performance can be enhanced.

Description

technical field

[0001] The present invention relates to communication technology, and in particular to a downlink transmission method and control equipment, a base station and a heterogeneous system in a heterogeneous network. Background technique

[0002] A typical wireless cellular network consists of base stations with the same level of transmission power and coverage, which can be classified as a homogeneous network. The same level of transmission power and coverage means that the transmission power and coverage are basically the same, or the transmission power The difference of and the difference of coverage are within the set range. In order to further improve the capacity and coverage performance, some low-power stations (Low Power Node, LPN) will be added within the deployment range of the macro station (Macro eNB), and the heterogeneous network (Heterogeneous network) will be formed by stations with different power. It can also be called a micro station. The purpo...
