Question: For a 7.68 Mcps TDD UE supporting HSDPA and E-DCH, what two probabilities determine the performance of E-HICH detection?
Option 1: False ACK Probability & Missed Detection Probability
Option 2: False NACK Probability & False ACK Probability
Option 3: Error Rate Probability & Throughput Reduction Probability
Option 4: Handover Failure Probability & Packet Loss Probability
Explanation: The correct answer is based on E-HICH detection performance metrics in UTRA for TDD mode. False NACK Probability refers to incorrectly detecting a Negative Acknowledgment (NACK) when an ACK was sent. False ACK Probability is the probability of mistakenly detecting an ACK when a NACK was sent, crucial for assessing E-HICH detection reliability and efficiency in HSDPA and E-DCH supported UEs.
