Question: What is a prerequisite for a User Equipment (UE) to support location-based conditional handover for an earth moving cell, specifically CondEvent D1, in an E-UTRA network?
Option 1: The UE must only support cho-r10.
Option 2: The UE needs to indicate support for either cho-r16 or ntn-Connectivity-EPC-r17.
Option 3: The UE has no additional feature support requirements beyond CondEvent D1.
Option 4: The UE must also indicate support for both cho-r16 and ntn-Connectivity-EPC-r17.
Explanation: For a UE to support location-based conditional handover for an earth moving cell (CondEvent D1), it is not just about supporting the event itself but also ensuring seamless integration with other network capabilities. Thus, indicating support for both cho-r16 (which relates to handover enhancements in Release 16) and ntn-Connectivity-EPC-r17 (which pertains to connectivity aspects in the Evolved Packet Core for non-terrestrial networks in Release 17) is crucial. This dual support ensures that the UE can effectively utilize location-based conditional handovers without disrupting network continuity or functionality, highlighting the importance of coordinated feature support in telecom networks.
