The present invention is applicable to the field of communication technologies, and provides a user scheduling method, a master base station, a user equipment, and a heterogeneous network. The method includes: receiving, by a master base station, a downlink interference indicator DII forwarded by a serving slave base station serving a user equipment UE, where the DII is sent to the serving slave base station by the UE attached to the serving slave base station, and when the DII is greater than a preset threshold, the DII indicates that the UE is in a high DII region; determining, according to the DII, whether the UE is in a high DII region; and if the UE is in a high DII region, allocating, when performing scheduling, fewer resources that may interfere with the UE. In the present invention, after receiving the DII fed back by the UE, the slave base station forwards the DII to the master base station; and when the UE is in a high DII region, the master base station actively allocates, when performing scheduling, fewer resources that may interfere with the UE attached to the slave base station, thereby reducing interference received by the UE attached to the slave base station.
