Question: In NG-RAN, which Barometric Pressure Sensor Positioning mode involves the UE calculating its vertical position without any assistance from the network, utilizing only its own measurements and potentially additional local sources?
Option 1: UE-Assisted Mode
Option 2: UE-Based Mode with Network Validation
Option 3: Hybrid Mode combining UE and Network Calculations
Option 4: Standalone Mode without Network Assistance
Explanation: The correct answer is Option 4 (Standalone Mode without Network Assistance) because, in NG-RAN's Barometric Pressure Sensor Positioning, the Standalone mode explicitly involves the UE performing its own calculations for determining the vertical component of its position, solely based on the UE's measurements and potentially other local sources, all without relying on any network assistance.
