Question: What is the primary criterion for determining the occupied bandwidth in a UTRA (Universal Terrestrial Radio Access) transmission?
Option 1: The frequency range where signal power is at its maximum
Option 2: The bandwidth containing 50% of the total integrated power, centered on the assigned channel frequency
Option 3: The bandwidth containing 99% of the total integrated power, centered on the assigned channel frequency
Option 4: The minimum bandwidth required for successful signal decoding by the User Equipment (UE)
Explanation: This option is correct because occupied bandwidth is defined as the measure of the bandwidth that contains 99% of the total integrated power for the transmitted spectrum, ensuring the vast majority of the signal's energy is accounted for within this bandwidth, crucial for efficient UTRA transmission and reception.
