Abstract

本发明提供了一种基于干扰的上行链路分数功率控制的方法和装置。该方法包括：向该服务基站所服务的UE发送测量配置消息，该测量配置消息用于指示UE对该服务基站的参考信号接收功率(RSRP)和相邻基站的RSRP进行测量；从该相邻基站接收该相邻基站的下行链路发射功率和期望的IoT操作点；接收UE所测量的该服务基站的RSRP值和相邻基站的RSRP值；基于服务基站和相邻基站的下行链路发射功率和RSRP值，估计服务基站和相邻基站与该UE之间的路损，并选择路损最小的相邻基站作为最强相邻基站；基于所估计的路损和用于该UE的上行链路传输的服务小区特定的发射功率，确定UE对该最强相邻基站的干扰；以及基于所确定的干扰和该最强相邻基站的该期望的IoT操作点，确定用于该UE的上行链路传输的UE特定的发射功率偏移。
