Question: In E-UTRAN, which of the following statements is true regarding the applicability of requirements for Dual Active Protocol Stack (DAPS) handover from Frequency Division Duplexing (FDD) to Time Division Duplexing (TDD)?
Option 1: Applies only to UE supporting solely FDD.
Option 2: Applies exclusively to UE supporting solely TDD.
Option 3: Is not applicable if the UE supports both FDD and TDD.
Option 4: Applies to UE that support both FDD and TDD.
Explanation: This is correct because the requirements for E-UTRAN FDD – TDD handover apply to User Equipment (UE) that supports both Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD), ensuring seamless handovers between different duplex modes for devices capable of operating in both, enhancing network flexibility and user experience.
