Question: In a multi-carrier Base Station (BS) scenario, as per 3GPP specifications, which of the following channel bandwidth scenarios for the outermost carrier is currently excluded from the unwanted emission requirements consideration?
Option 1: Channel bandwidth of the outermost carrier greater than or equal to 5 MHz
Option 2: Channel bandwidth of the outermost carrier less than 5 MHz
Option 3: Channel bandwidth of the outermost carrier exactly equal to 10 MHz
Option 4: Channel bandwidth of the outermost carrier greater than 20 MHz
Explanation: According to the specifications, all scenarios for channel bandwidths of the outermost carrier less than 5 MHz are set aside for further study, implying that the current considerations and requirements do not fully encompass this specific scenario. This exclusion is crucial for understanding the scope of the unwanted emission requirements in multi-carrier BS setups.
