Question: In NG-RAN, what is the primary purpose of RTK Auxiliary Station Data provided to a GNSS receiver for UE positioning using the MAC N-RTK technique?
Option 1: To transmit absolute geodetic coordinates for direct location fixing.
Option 2: To offer real-time traffic updates for optimizing navigation routes.
Option 3: To provide atmospheric condition data for signal correction.
Option 4: To supply relative geodetic coordinates of Auxiliary Reference Stations, facilitating precise positioning.
Explanation: RTK Auxiliary Station Data is crucial for the MAC N-RTK technique in NG-RAN. It provides the GNSS receiver with the locations of all Auxiliary Reference Stations relative to a Master Reference Station, enabling the UE to accurately determine its location by leveraging the known positions of these reference stations.
