Question: For a 1.28 Mcps TDD UE supporting HSDPA and E-DCH, what two probabilities determine the performance of E-HICH detection, according to 3GPP specifications for Release 7 and later releases?
Option 1: False ACK Probability and Missed Detection Probability
Option 2: Bit Error Rate (BER) and Frame Erasure Rate (FER)
Option 3: False NACK Probability and False ACK Probability
Option 4: Blocking Probability and Dropping Probability
Explanation: The correct answer, Option 3, is based on the understanding of E-HICH (Enhanced High-Speed Dedicated Physical Control Channel Indicator) detection performance metrics in the context of UTRA (UMTS Terrestrial Radio Access) TDD (Time Division Duplex) systems. - False NACK Probability refers to the likelihood of incorrectly detecting a Negative Acknowledgment (NACK) when an ACK (Acknowledgment) was actually sent. - False ACK Probability is the probability of mistakenly detecting an ACK when a NACK was sent. These two probabilities are crucial for assessing the reliability and efficiency of the E-HICH detection mechanism in HSDPA (High-Speed Downlink Packet Access) and E-DCH (Enhanced Dedicated Channel) supported UEs.
