Question: In UE-assisted mode for User Equipment (UE) positioning in Next Generation Radio Access Network (NG-RAN), what additional measurement may the Global Navigation Satellite System (GNSS) receiver report, if requested and supported?
Option 1: Signal Strength Indicators of nearby base stations
Option 2: Round-Trip Time (RTT) measurements for cellular signals
Option 3: UE's battery life and storage capacity
Option 4: Carrier Phase measurements (also known as Accumulated Delta Range), along with associated quality measurements
Explanation: In the context of UE-assisted mode for positioning in NG-RAN, the GNSS receiver can provide detailed measurements to enhance location accuracy. Among the options provided, only Carrier Phase measurements (Accumulated Delta Range) are directly relevant to enhancing the precision of GNSS-based location calculations, as mentioned in the context of UE-assisted mode capabilities. This is particularly useful for fine-tuning the UE's location, leveraging the strengths of both GNSS and NG-RAN infrastructure.
