摘要： 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.

摘要翻译： 本发明可应用于通信技术领域，提供用户调度方法，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，则当执行调度时，分配可能干扰UE的更少的资源。 在本发明中，在接收到由UE反馈的DII之后，从基站将DII转发给主基站; 并且当UE处于高DII区域时，主基站在执行调度时主动分配较少的资源，这些资源可能会干扰附属于从基站的UE，从而减少由附属到从基站的UE接收到的干扰 。

摘要： Embodiments of the present invention provide a precoding information obtaining method and a device. The method includes: separately precoding, by a network device by using N sub-codebooks, a pilot group including K pilots to obtain N precoded pilot groups, where the sub-codebooks are subsets of a precoding codebook, the precoding codebook includes M precoding vectors, each sub-codebook includes K precoding vectors; sending, by the network device, a precoded pilot group to a terminal device in each of W RB groups; and receiving, by the network device, precoding information fed back by the terminal device for any one of W precoded pilot groups. According to the precoding information obtaining method and the device, the network device divides a precoding codebook into multiple sub-codebooks, and a quantity of precoding vectors in each sub-codebook is relatively small. Therefore, a quantity of pilot signals sent by the network device in each RB group is reduced, and pilot overheads in each RB group are reduced.
