Question: What triggers an ng-eNB (Next Generation evolved Node B) to make measurements of radio signals for a target User Equipment (UE) in the context of UE positioning in NG-RAN?
Option 1: Periodic self-initiated scans by the ng-eNB
Option 2: Requests from the Location Management Function (LMF), which can be either on demand or periodic
Option 3: Direct requests from the target UE seeking to determine its own location
Option 4: Scheduled maintenance windows predetermined by the network operator
Explanation: In the NG-RAN architecture, the Location Management Function (LMF) plays a central role in managing positioning activities. The ng-eNB relies on instructions from the LMF to initiate measurements for UE positioning, ensuring coordinated and efficient use of network resources for location services.
