Question: In 3GPP-compliant FDD Base Stations (BS), what is the primary metric used to determine the performance requirement of Dedicated Channels (DCH) under birth/death propagation conditions?
Option 1: Received Signal Strength Indication (RSSI)
Option 2: Block Error Ratio (BLER) at a specified Eb/N0 limit
Option 3: User Equipment (UE) throughput measurement
Option 4: Handover Success Rate (HSR)
Explanation: The correct answer is Option 2 because, according to the telecom standards for Base Station conformance testing, the performance of Dedicated Channels (DCH) in varying propagation conditions is evaluated based on the Block Error Ratio (BLER) achieved at a specific Eb/N0 (Energy per bit to Noise power spectral density ratio) threshold. This metric directly reflects the channel's error resilience and quality under defined signal-to-noise conditions, making it crucial for assessing DCH performance in birth/death propagation scenarios.
