Abstract

A network element for configuring a Remote Interference Monitoring Reference Signal (RIM-RS) is disclosed. The network element transmits RIM-RS resource configuration and Information of Things (IoT) measurement and reporting configuration information to a base station. The base station conducts the IoT measurement and ducting phenomenon detection according to the received configuration, and transmits the results to the network element. The base station determines the number of repetition and/or near-far indication based on the received information and transmits the number of repetition and near-far indication to the base station. The base station then transmits the RIM-RS according to the received repetition and near-far indication.
