Question: In NG-RAN, what is the expected typical sequence of LPP (Location Services) procedures between a UE and an LMF, despite allowing flexibility in ordering?
Option 1: Location Information Transfer → Capability Transfer → Assistance Data Transfer
Option 2: Assistance Data Transfer → Location Information Transfer (without capability exchange)
Option 3: Capability Transfer & Assistance Data Transfer can be skipped if QoS is met directly with Location Information Transfer
Option 4: Capability Transfer → Assistance Data Transfer → Location Information Transfer (measurements and/or location estimate)
Explanation: This sequence makes logical sense in the context of positioning procedures. First, the UE informs the network about its Capability to understand its limitations and potential for location determination. Next, based on this, the network provides Assistance Data tailored to the UE's capabilities to aid in precise location measurement or estimation. Finally, with the assistance data utilized, the UE shares the resulting Location Information (measurements or a direct location estimate) back with the network, fulfilling the positioning request while aiming to meet the specified QoS (Quality of Service). This order ensures an efficient and effective use of resources for accurate positioning.
