Abstract: The present invention 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.
Abstract translation: 本发明提供了一种用户调度方法，主基站，用户设备和异构网络。 该方法包括：由主基站接收由服务于用户设备UE的服务从基站转发的下行干扰指示符DII，其中，DII由附属于服务从基站的UE发送到服务从基站 并且当DII大于预设阈值时，DII指示UE处于高DII区域; 根据DII确定UE是否处于高DII区域; 并且如果UE处于高DII区域，则在执行调度时分配较少的可能与UE干扰的资源。
