Question: For a multi-carrier E-UTRA Base Station (BS) transmitting carriers of varying channel bandwidths, what determines the ACLR and Operating band unwanted emission requirements for the overall transmission?
Option 1: The narrowest channel bandwidth among all carriers dictates the requirements.
Option 2: The channel bandwidth of the outermost carriers (those ≥5 MHz) sets the requirements, applied individually to each side of the transmitted carrier group.
Option 3: A weighted average of all channel bandwidths is used to determine a single set of requirements for the entire transmission.
Option 4: Only the widest channel bandwidth among all carriers influences these specific emission requirements.
Explanation: In multi-carrier E-UTRA Base Station scenarios with varying channel bandwidths, ACLR and Operating band unwanted emission requirements are crucial for minimizing interference. The correct approach is to consider the channel bandwidth of the outermost carriers (≥5 MHz) for these requirements, applying them to each side of the transmitted carrier group to manage emissions effectively across the entire transmission spectrum.
