Question: For which UE categories does the connModeMeasInterFreq-r17 field apply, regarding support for inter-frequency neighbor cell measurements in RRC_CONNECTED mode?
Option 1: UEs of any ue-Category-NB
Option 2: UEs of Category 1 and above (ue-Category-MBB)
Option 3: UEs specifically categorized for low-bandwidth operations (ue-Category-LB)
Option 4: All UE categories supporting RRC_CONNECTED mode
Explanation: The correct answer is Option 1 because the connModeMeasInterFreq-r17 field is applicable only for UEs of any ue-Category-NB, implying support for inter-frequency neighbor cell measurements in RRC_CONNECTED mode is particularly relevant or limited to Narrowband (NB) IoT related UE categories.
