Question: In UTRA TDD, what is the primary metric used to determine the performance requirement of a Dedicated Channel (DCH) in static propagation conditions for each individual data rate?
Option 1: Signal-to-Noise Ratio (SNR)
Option 2: Frame Error Rate (FER)
Option 3: Throughput
Option 4: Block Error Ratio (BLER)
Explanation: In UTRA TDD, the performance of a Dedicated Channel (DCH) under static propagation conditions is crucial for reliable data transmission. Block Error Ratio (BLER) is the key performance indicator because it directly reflects the error rate in data blocks, vital for assessing the quality of service for each supported data rate on the DCH, impacting the overall user experience.
