Question: In a UTRAN with Downlink maximum power limited, what is the expected behavior of the Downlink Power Control in a User Equipment supporting DCH Enhancement for UMTS after the limitation is released?
Option 1: The UE's DL power control should immediately revert to its pre-limitation gain setting.
Option 2: The UE must enter a low-power state for a brief period before resuming normal operation.
Option 3: The required DL power in the UE should not exhibit a 'wind up effect', meaning no increase during the limitation period.
Option 4: The UE's DL power control will automatically adjust to a higher gain setting to compensate for the previous limitation.
Explanation: This is correct because the question references preventing a 'wind up effect' in downlink power control after a maximum power limitation release. A 'wind up effect' implies an undesirable increase in required DL power during the limitation period. Option 3 accurately reflects the expected behavior, ensuring the UE's downlink power requirements do not unnecessarily increase following a limitation release.
