16.20.3 Data Collection and Reporting

The following information can be configured to be reported by an NG-RAN node:

• Predicted resource status information, including predicted radio resource status per slice;
• UE performance feedback, including per-slice UE performance;
• Measured UE trajectory;
• Energy Cost (EC);
• Predicted slice available capacity.

The collection and reporting of the above information are configured through the Data Collection Reporting Initiation procedure, while the actual reporting is performed through the Data Collection Reporting procedure.

The collection of measured UE trajectory and UE performance feedback is triggered at successful Handover.

Cell-based UE trajectory prediction, which can be used, e.g., for the Mobility Optimization use case, is transferred to the target NG-RAN node via the Handover Preparation procedure to provide information for, e.g., subsequent mobility decisions. Cell-based UE trajectory prediction is limited to the first-hop target NG-RAN node.

An NG-RAN node may derive predicted CCO issues and the corresponding future coverage states for its affected cells and beams. The NG-RAN node may notify its neighbour NG-RAN nodes, via the NG-RAN Node Configuration Update procedure, about the future coverage state changes together with modification cause and time information. The NG-RAN node may also notify its neighbour NG-RAN nodes that previously notified coverage state changes together with the corresponding modification cause have been cancelled.

At any given point in time, for a list of predicted affected cells and beams, there is only one predicted CCO issue generated by a gNB.
