Section: 7.2 Remote Interference Management
Content: The Remote Interference Management function in non-split gNB case is specified in TS 38.300[ NR; NR and NG-RAN Overall description; Stage-2 ]  [2]. In case of split gNB architecture, in the victim set, a gNB-DU detects the remote interference. If remote interference is detected, the gNB-DU can send out the RIM-RS. In the aggressor set, if a gNB-DU detects the RIM-RS sent by the victim gNB(s), it sends to the gNB-CU the RIM-RS detection status and the victim Set ID. The gNB-CU acts as a coordinator on behalf of its affiliated gNB-DUs, where the gNB-CU merges the outgoing RIM information received from its gNB-DUs in the aggressor set and forwards the merged information to all the gNBs in the victim set. Similarly, in the victim set, the gNB-CU distributes the incoming RIM information to all the gNB-DUs in the set, as indicated in the RIM information received from the aggressor set. In addition, to facilitate consolidation of RIM information, the gNB-DU provides the associated aggressor set ID and the victim set ID of each serving cell to the gNB-CU.
