Question: What is a prerequisite for a User Equipment (UE) that supports handover from E-UTRA/5GC to NR TDD FR2-2 in terms of additional UE capabilities?
Option 1: Support for eutra-5GC-r15 and RRM measurements for FR2-2
Option 2: Only support for eutra-5GC-r15, with RRM measurements for FR2-2 being optional
Option 3: Capability for handover to NR FDD bands as well as TDD
Option 4: UE category higher than a specified threshold (e.g., Cat 18 or above)
Explanation: For a UE to support handover from E-UTRA/5GC to NR TDD FR2-2, it must have two key capabilities: Support for eutra-5GC-r15, indicating compatibility with earlier specified 5G core network standards, and RRM measurements for FR2-2, crucial for managing radio resources efficiently during handovers in the FR2-2 frequency range.
