22.2.4 Inference, Monitoring and Management
For Network-side model, the CSI measurement and reporting is used to acquire input data for inference.
NOTE: For Network-side model, network side additional conditions are considered known via network implementation.
For Network-side model, the gNB is responsible for performance monitoring (i.e., calculates performance metrics). There are no additional impacts on the UE for monitoring and management, except for being configured to provide the required measurement/data. Additionally, the UE is not informed about any gNB-side management decision.
For UE-side model, the gNB initiates performance monitoring, and makes management decisions based on the performance monitoring results. The UE can be configured to send either the measurement reports or the calculated performance metrics.
