Question: What action does a User Equipment (UE) take when it estimates that a specific Transport Format Combination (TFC) would exceed its maximum transmit power in a UTRA FDD network?
Option 1: The UE automatically switches to a different radio access technology (RAT) to accommodate the TFC.
Option 2: The UE increases its maximum transmit power to support the estimated TFC requirement.
Option 3: The UE notifies the network, which then adjusts the TFC to match the UE's maximum transmit power.
Option 4: The UE limits the usage of transport format combinations for the assigned transport format set.
Explanation: This action prevents the UE from exceeding its maximum transmit power, helping network operators maximize coverage. By limiting certain transport format combinations, the UE operates within its power constraints, optimizing network performance and user experience.
