Question: In a UTRA FDD network, what metric determines the receive characteristic of a Dedicated Channel (DCH) when it operates in open loop transmit diversity mode?
Option 1: Signal-to-Noise Ratio (SNR)
Option 2: Frame Erasure Rate (FER)
Option 3: Block Error Ratio (BLER)
Option 4: Carrier-to-Interference Ratio (C/I)
Explanation: In UTRA FDD networks, a Dedicated Channel's receive characteristic in open loop transmit diversity mode is evaluated based on Block Error Ratio (BLER), measuring the ratio of incorrectly received blocks to total blocks sent, crucial for assessing channel reliability and error resilience.
