Question: Which of the following statements accurately describes the current support for OTDOA (Observed Time Difference of Arrival) Positioning in NG-RAN as per the specified functional requirements?
Option 1: Both UE-assisted and UE-based OTDOA positioning are supported.
Option 2: Only UE-based OTDOA positioning is currently supported.
Option 3: OTDOA positioning support is exclusively for network-assisted modes.
Option 4: Currently, only UE-assisted OTDOA positioning is supported.
Explanation: This answer is correct because the specified functional requirements explicitly state that "only the UE-assisted OTDOA positioning is supported" in the current version of the specification. This indicates a clear limitation to UE-assisted mode, excluding other modes like UE-based or network-assisted modes from the current support scope. Understanding the distinction between UE-assisted and other positioning modes is crucial for implementing accurate location services in NG-RAN.
