Question: Upon receiving an sl-ReportConfigToAddModList with an existing sl-ReportConfigId, what action does the UE take regarding measurement reporting for each associated sl-MeasId in the VarMeasConfigSL?
Option 1: The UE initiates a new periodical reporting timer for this sl-MeasId.
Option 2: The UE updates the sl-TimeToTrigger value without stopping the existing timer.
Option 3: The UE removes the measurement reporting entry from VarMeasReportListSL and stops/reset the associated reporting timer.
Option 4: The UE ignores the received configuration for this specific sl-MeasId.
Explanation: When a UE receives an updated sidelink reporting configuration that matches an existing ID, it must reconfigure the entry and, for each associated measurement ID, ensure consistency by removing any existing measurement report entries from the list and stopping (then resetting) the periodic reporting timer to align with the new configuration.
