Question: For a User Equipment (UE) operating in Frequency Division Duplexing (FDD) mode, what is a prerequisite for supporting Downlink (DL) channel quality reporting for a non-anchor carrier in Msg3?
Option 1: The UE must support at least one of the LTE TDD bands.
Option 2: The UE's RRC protocol version must be updated to Release 15 or later.
Option 3: The UE must support any ue-Category-NB (Narrow Band) category.
Option 4: The UE has to be capable of transmitting on multiple carriers simultaneously.
Explanation: This is because the feature of DL channel quality reporting for a non-anchor carrier in Msg3 for FDD is only applicable if the User Equipment (UE) supports any ue-Category-NB, highlighting the importance of UE categories in determining device capabilities and features, especially in relation to narrowband operations.
