Question: What is a mandatory additional capability for a UE that supports autonomous GNSS position fix in RRC_CONNECTED, as per E-UTRA specifications?
Option 1: eMBB (Enhanced Mobile Broadband) support
Option 2: ntn-Connectivity-EPC-r17 support
Option 3: Multi-antenna transmission capability
Option 4: Voice over LTE (VoLTE) capability
Explanation: According to E-UTRA specifications, if a UE indicates support for autonomous GNSS position fix in RRC_CONNECTED, it is also required to support ntn-Connectivity-EPC-r17. This ensures seamless integration of autonomous GNSS fixes with the Evolved Packet Core (EPC) network for efficient location services and other enhancements like reporting GNSS validity duration.
