Question: In E-UTRAN Standalone mode for UE positioning, what additional information is the UE expected to report alongside its geographical coordinates (latitude, longitude, and possibly altitude)?
Option 1: An indication of the TBS method usage and potentially other utilized positioning methods.
Option 2: The exact timing of when the location was last updated.
Option 3: A list of nearby cell towers for further triangulation.
Option 4: The UE's current battery level to assess report reliability.
Explanation: In E-UTRAN Standalone mode, for accurate positioning and to understand the basis of the location fix, the UE is expected to provide not just its geographical coordinates but also insights into how this fix was determined. Reporting the use of the TBS method and possibly other methods used, helps in assessing the accuracy and reliability of the reported location, given that different methods may have varying levels of precision and uncertainty.
