Question: In UE-based mode utilizing Bluetooth Angle of Departure (AoD) for positioning in NG-RAN, what additional information should the User Equipment (UE) report alongside the estimated location coordinates?
Option 1: Only the signal strength of the Bluetooth signals used for positioning.
Option 2: An indication that Bluetooth method is used and possibly other positioning methods used to calculate the fix, as well as an estimate of the location uncertainty if available.
Option 3: The battery life of the UE and the timestamp of when the location was estimated.
Option 4: Details of nearby cellular towers for enhanced triangulation.
Explanation: In UE-based mode with Bluetooth AoD, accurately conveying the positioning method(s) used is crucial for the network to assess the location's reliability. Including an estimate of the location uncertainty, if available, provides valuable context about the precision of the reported coordinates. This information is vital for NG-RAN to effectively manage and potentially enhance the UE's positioning experience.
