Question: In E-UTRAN, which metric reported by User Equipment (UE) is particularly useful for assessing RF signal quality and overall service quality in the context of Network (NW) planning?
Option 1: Timing Advance Measurements
Option 2: Channel Quality Indicator (CQI)
Option 3: Power Resource Utilization Percentage
Option 4: Uplink Interference Power
Explanation: The Channel Quality Indicator (CQI) is a metric reported by User Equipment (UE) that reflects the quality of the RF signal in the cell. It is specifically highlighted as useful for assessing both RF signal quality and overall service quality, making it particularly relevant for Network (NW) planning purposes. While Timing Advance Measurements provide insights into UE distance from the cell antenna, and Power Resource Utilization Percentage and Uplink Interference Power are important for other aspects of network optimization, CQI is directly linked to signal quality assessment.
