    based, determined by parameter reportType. For periodical reporting the 

    same parameters as in LTE and UMTS apply. For event based reporting, 

    parameter eventListForEventTriggeredMeasurement configures the event type, 

    namely ‘out of coverage’ or ‘L1 event’. In case ‘L1 event’ is selected as 

    namely "out of coverage" or "L1 event". In case "L1 event" is selected as 

    event type, the logging is performed according to parameter loggingInterval

    at regular intervals only when the conditions indicated by eventThresholdL1, 

    hysteresisL1, timeToTriggerL1 (defining the thresholds, hysteresis and time 

    to trigger) are met and if UE is ‘camped normally’ state (TS 38.331, TS 38.304).

    In case ‘out of coverage’ is selected as event type, the logging is performed 

    according to parameter loggingInterval at regular intervals only when the UE 

    is in ‘any cell selection’ state. Furthermore, logging is performed 

    immediately upon transition from the ‘any cell selection’ state to the 

    ‘camped normally’  state (TS 38.331, TS 38.304).";
