Question: What is a prerequisite for a User Equipment (UE) to support HARQ feedback transmission for the first SPS PDSCH transmission after activation in coverage enhancement mode A?
Option 1: The UE must support only ntn-SemiStaticHarqDisableSPS-r18.
Option 2: The UE must operate exclusively in E-UTRA FDD mode.
Option 3: The UE's RRC connection must be established with a specific APN.
Option 4: The UE must also support ce-ModeA-r13 and ntn-Connectivity-EPC-r17.
Explanation: For a UE to support HARQ feedback transmission for the first SPS PDSCH transmission after activation in coverage enhancement mode A, it is technically mandatory that the UE also supports both coverage enhancement mode A (ce-ModeA-r13) and non-terrestrial network connectivity with EPC (ntn-Connectivity-EPC-r17). This ensures the UE can properly handle the enhanced coverage features while maintaining connectivity through non-terrestrial means if necessary, highlighting the interdependence of these features for effective operation in such scenarios.
