Question: For a User Equipment (UE) to support NSSS-Based RRM measurements for Frequency Division Duplexing (FDD), which of the following conditions must be met?
Option 1: The UE must support at least one of the FDD bands specified in cellular standards for FDD operations.
Option 2: The UE must support any ue-Category-NB.
Option 3: The UE must have a minimum of two transmitting antennas for diversity.
Option 4: The UE must be capable of advanced transmission modes typically used for enhanced RRM capabilities.
Explanation: NSSS-Based RRM measurements for FDD are applicable if the User Equipment (UE) supports any ue-Category-NB, highlighting a direct dependency on this category for the feature's applicability, emphasizing UE categories' importance in determining device capabilities and RRM functionalities.
