Question: For a multi-carrier Base Station transmitting both E-UTRA and UTRA carriers, where the outermost carriers have a bandwidth of ≥5 MHz, what determines the ACLR and Operating Band Unwanted Emission requirements?
Option 1: The type of modulation used across all transmitted carriers.
Option 2: The average transmission power of the combined carrier group.
Option 3: The bandwidth of the innermost carriers within the group.
Option 4: The Radio Access Technology (RAT) being used on each of the outermost carriers.
Explanation: This is because, according to specifications for multi-carrier Base Stations transmitting both E-UTRA and UTRA, the ACLR and Operating Band Unwanted Emission requirements are dictated by the Radio Access Technology (RAT) in use on the outermost carriers (those with a bandwidth of ≥5 MHz), ensuring each side meets its respective RAT's emissions standards.
