Question: What is the primary reason for verifying that a User Equipment (UE)'s minimum transmit power in each carrier is below a certain threshold when operating with multiple carriers?
Option 1: To ensure consistent signal strength across all connected devices.
Option 2: To prevent overheating of UE hardware components during prolonged use.
Option 3: To maintain backward compatibility with older network infrastructure.
Option 4: To minimize interference to other channels and preserve system capacity.
Explanation: The correct answer highlights the key reason for regulating UE's minimum transmit power: to prevent increased interference to other channels, which helps maintain or increase overall system capacity, ensuring efficient spectrum use and minimizing disruptions to other network users.
