Question: What is a prerequisite for a User Equipment (UE) to support handover from E-UTRA/5GC to NR FDD FR2, as per the latest specifications?
Option 1: The UE must support only NR FDD FR2 and not any other frequency range.
Option 2: The UE must support the associated Radio Access Technologies (RATs) and eutra-5GC-r15.
Option 3: The UE needs to have a specific minimum bandwidth capability for both E-UTRA and NR.
Option 4: Handover support is optional for all UEs, regardless of RAT or feature support.
Explanation: For a UE to be capable of handing over from E-UTRA/5GC to NR FDD FR2, it fundamentally needs to understand and work with both the originating (E-UTRA/5GC) and target (NR FDD FR2) radio access technologies. Additionally, since this feature is tied to specifications outlined in eutra-5GC-r15, support for this specific feature set is also a necessity.
