Question: In a UTRA TDD system, what is the primary objective of downlink power control from the UE receiver's perspective?
Option 1: To maximize the downlink transmission power for enhanced coverage
Option 2: To converge to the required link quality set by the network while minimizing downlink power usage
Option 3: To prioritize outer loop power control based on DCCH over DTCH
Option 4: To maintain a constant BLER target across both DCCH and DTCH
Explanation: The correct answer aligns with the principle of downlink power control, emphasizing the balance between achieving the required link quality (set by the network) and using the lowest possible power in the downlink. This approach is energy-efficient and helps manage interference within the network.
