摘要： A WLAN coordinated data transmission method, system, and relevant device are disclosed. The WLAN coordinated data transmission method includes: detecting, by an offloading scheduling controller, whether the number of MAC SDUs buffered in a MAC SDU queue of a mobile communication module exceeds a preset threshold, and, if so, packing a part of the MAC SDUs into a MAC PDU, and sending the MAC PDU to a coordination mode management module through an interface of the mobile communication module; sending, by the coordination mode management module, the MAC PDU containing the packed part of the MAC SDUs through an LLC protocol layer to a WLAN module for transmission; and packing, by the offloading scheduling controller, a remaining part of the MAC SDUs buffered in the MAC SDU queue into a MAC PDU, and transmitting the MAC PDU through the mobile communication module. The present invention uses a WLAN to accelerate data transmission of a Femtocell and shorten the air interface transmission delay of a system.

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 。
