Question: What is a prerequisite for a User Equipment (UE) to support `loggedMeasIdleEventOutOfCoverage-r17` in RRC_IDLE state, as per 3GPP specifications?
Option 1: The UE must also support `loggedMeasurementsIdle`.
Option 2: The UE needs to be in RRC_CONNECTED state initially.
Option 3: The network must have previously logged measurements for the UE's current cell.
Option 4: The UE should have a minimum of two active bearers.
Explanation: According to the specifications, for a UE to support `loggedMeasIdleEventOutOfCoverage-r17` (event-triggered logged measurements for being out of coverage in RRC_IDLE state upon network request), it is mandatory that the UE also supports `loggedMeasurementsIdle`. This ensures the UE can perform and log measurements even when in an idle state, aligning with the requirements for out-of-coverage event reporting.
