Question: For a multi-carrier E-UTRA Base Station transmitting carriers of different E-UTRA channel bandwidths, what determines the ACLR and Operating band unwanted emission requirements for the outermost carriers with a bandwidth of ≥5 MHz?
Option 1: The average channel bandwidth of all transmitted carriers
Option 2: The smallest channel bandwidth among the group of carriers
Option 3: The channel bandwidth of each individual outermost carrier
Option 4: A fixed default bandwidth specified for multi-carrier operations
Explanation: In a multi-carrier E-UTRA Base Station scenario where carriers of different channel bandwidths (all ≥5 MHz) are transmitted, the ACLR and Operating band unwanted emission requirements are specifically tailored to each outermost carrier's unique channel bandwidth. This ensures that the emissions from each edge of the transmission group meet the standards for their respective bandwidths, preventing interference and ensuring compliance with regulatory requirements. Thus, the correct approach is to apply the corresponding requirements based on the channel bandwidth of each individual outermost carrier.
