Question: What type of measurements, excluding GNSS, can be utilized by the E-SMLC or UE to determine or validate a location estimate in an E-UTRAN?
Option 1: Downlink positioning measurements, path loss, and signal strength related measurements
Option 2: Uplink transmission power and neighboring cell broadcast information
Option 3: Handover success rates and inter-cell interference metrics
Option 4: UE's battery life and current network congestion levels
Explanation: In E-UTRAN, to enhance location services, additional non-GNSS measurements can be leveraged. These include downlink positioning measurements, which involve signals sent from the network to the UE, as well as path loss and signal strength related measurements, which provide insights into the signal's attenuation and power upon arrival at the UE. These metrics are crucial for triangulating or estimating the UE's location accurately.
