Question: For a UTRA FDD UE (Release 8 and later) in CELL_FACH state, what is the primary factor determining the receiver characteristics of the E-DCH Acquisition Indicator (E-AI)?
Option 1: Transmission Power of the E-AI signature
Option 2: Type of UTRA Technology Used
Option 3: State of the UE (e.g., Idle, Connected)
Option 4: Probability of Correct Detection (Pde) of the E-AI Signature
Explanation: The correct answer is Option 4 because the receiver characteristics of the E-DCH Acquisition Indicator (E-AI) are directly determined by the Probability of Correct Detection (Pde), measuring the likelihood of correctly detecting the E-AI signature if transmitted and received, emphasizing detection accuracy for reliable Enhanced Uplink communication in the CELL_FACH state.
