    • Systems and methods can be implemented on a user device and eNBs to manage uplink interference. A user device associated with a serving base station may detect downlink interference from one or more interfering base stations that are different from the serving base station. The user device that detects downlink interference can determine an uplink radio resource set from a plurality of predefined uplink radio resource sets based, at least in part, on the detected downlink interference. The user device can then transmit to the serving base station a radio resource indication identifying the determined uplink radio resource set to facilitate uplink interference management.
    • 可以在用户设备和eNB上实现系统和方法来管理上行链路干扰。 与服务基站相关联的用户设备可以检测来自与服务基站不同的一个或多个干扰基站的下行链路干扰。 检测下行链路干扰的用户装置可以至少部分地基于检测到的下行链路干扰来确定从多个预定义的上行链路无线电资源集合中的上行链路无线电资源集合。 然后,用户设备可以向服务基站发送标识所确定的上行链路无线电资源集合的无线电资源指示,以便于上行链路干扰管理。
