Question: In NG-RAN, which of the following is NOT a supported positioning mode for estimating UE position using Bluetooth beacons?
Option 1: Network-Based
Option 2: Standalone
Option 3: UE-assisted
Option 4: UE-based
Explanation: The three supported positioning modes for Bluetooth positioning in NG-RAN are: Standalone (UE handles measurements and location computation), UE-assisted (UE provides measurements to the Location Management Function for network-based computation), and UE-based (combines UE-performed measurements with network assistance). Network-Based is not among these modes.
