3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [1] apply.
Immediate MDT: MDT functionality involving measurements performed by the UE in CONNECTED state and reporting of the measurements to RAN available at the time of reporting condition as well as measurements by the network for MDT purposes.
Logged MDT: MDT functionality involving measurement logging by UE in IDLE mode, INACTIVE state, CELL_PCH, URA_PCH states and CELL_FACH state when second DRX cycle is used (when UE is in UTRA) for reporting to eNB/RNC/gNB at a later point in time, and logging of MBSFN measurements by E-UTRA UE in IDLE and CONNECTED modes.
Management Based MDT PLMN List: MDT PLMN List applicable to management based MDT.
MDT measurements: Measurements determined for MDT.
MDT PLMN List: A list of PLMNs where MDT is allowed for a user. It is a subset of the EPLMN list and RPLMN at the time when MDT is initiated.
Signalling Based MDT PLMN List: MDT PLMN List applicable to signalling based MDT.
