Question: Which of the following NBAP functions enables the CRNC to adjust the downlink power level of one or more Radio Links to prevent power drifting issues, specifically applicable to Frequency Division Duplexing (FDD) mode?
Option 1: DL Power Drifting Correction [FDD]
Option 2: DL Power Timeslot Correction [TDD]
Option 3: Radio Link Management
Option 4: Cell Configuration Management
Explanation: This answer is correct because it specifically addresses downlink power drifting between Radio Links in FDD mode. In contrast, Option 2 is TDD-specific and focuses on UE interference-based timeslot adjustments. Options 3 and 4 are broader management functions not focused on FDD downlink power adjustments.
