Question: What is the primary purpose of E-UTRAN UE power headroom measurement in a telecommunication network?
Option 1: To evaluate the performance of downlink signal strength
Option 2: To analyze UE power distribution and troubleshoot coverage holes for uplink signals
Option 3: To measure the quality of service (QoS) for voice calls only
Option 4: To optimize the network's energy consumption for data transmission
Explanation: E-UTRAN UE power headroom measurement is crucial for analyzing UE power distribution, which helps in identifying whether the uplink signal strength can be increased or not. This information is vital for troubleshooting coverage holes and evaluating power control performance to ensure QoS while optimizing energy consumption.
