Question: In a handover scenario from UTRAN FDD to E-UTRAN TDD, what is the primary purpose of verifying E-UTRAN TDD RSRP measurement accuracy in CELL_DCH state for a UE requiring compressed mode?
Option 1: To optimize E-UTRAN TDD uplink transmission power
Option 2: To evaluate UTRAN FDD downlink signal strength
Option 3: To ensure accurate handover decision-making based on RSRP measurements
Option 4: To test UE's compressed mode functionality under stress conditions
Explanation: Accurate RSRP (Reference Signal Received Power) measurements are crucial for the network to make informed handover decisions, ensuring seamless connectivity and maintaining service quality. By verifying the measurement accuracy in CELL_DCH state for UEs needing compressed mode for E-UTRAN TDD measurements, the test ensures that handovers from UTRAN FDD to E-UTRAN TDD are based on reliable RSRP values, directly impacting the efficiency of the handover process.
