Question: What is a prerequisite for a User Equipment (UE) to support `ce-PDSCH-14HARQProcesses-Alt2` in FDD when operating in coverage enhancement mode A?
Option 1: The UE must operate exclusively in TDD mode.
Option 2: The UE needs to support only 12 DL HARQ processes.
Option 3: The UE has to be capable of only MIMO (Multiple Input Multiple Output) operations.
Option 4: The UE must also indicate support for `ce-PDSCH-14HARQProcesses`.
Explanation: For a UE to support the alternative HARQ-ACK delay solution for 14 DL HARQ processes in coverage enhancement mode A, it must also support the base 14 DL HARQ processes capability. This ensures backward compatibility and foundational support for enhanced capabilities.
