Question: In WLAN positioning within an NG-RAN, what is the primary purpose of collecting UE's WLAN receiver measurements (e.g., RSSI, RTT) in relation to geographical coordinates of reference WLAN access points?
Option 1: To optimize WLAN Access Point deployment for enhanced coverage.
Option 2: To authenticate UE identity for secure network access.
Option 3: To estimate the UE's position using a location determination algorithm.
Option 4: To adjust WLAN transmission power for reduced interference.
Explanation: The correct answer highlights the core function of collecting measurements in WLAN positioning - to apply a location determination algorithm that utilizes databases of reference points' geographical coordinates to estimate the UE's position, fundamental for determining the User Equipment's location within the NG-RAN using WLAN positioning methods.
