Question: In a UMTS FDD downlink compressed mode scenario, what is a key aspect of UE behavior being verified when receiving a Dedicated Physical Channel (DPCH) with sufficiently low Downlink (DL) power?
Option 1: The UE's ability to maintain a target Block Error Rate (BLER) while applying signaled Delta Signal-to-Interference Ratio (SIR) values in its outer loop power control.
Option 2: The UE's capability to switch to a higher transmission power to compensate for the compressed mode.
Option 3: The UE's efficiency in reducing battery consumption during compressed mode operations.
Option 4: The UE's handling of simultaneous voice and data transmissions in compressed mode.
Explanation: In UMTS FDD downlink compressed mode, maintaining link quality is crucial. The correct answer focuses on the UE preserving a target BLER with low DL power and incorporating network-signaled Delta SIR values into its outer loop power control algorithm to ensure effective transmission power adjustments for reliable communication.
