Question: What is a prerequisite for a User Equipment (UE) to support npdsch-MultiTB-r16 for multiple TB scheduling in the downlink for FDD?
Option 1: The UE must support Category M1.
Option 2: The UE must also indicate support of twoHARQ-Processes-r14.
Option 3: The UE needs to be capable of TDD (Time Division Duplex) mode only.
Option 4: The UE has to support a minimum of four Rx antennas.
Explanation: According to the specifications, for a UE to support npdsch-MultiTB-r16, it must also indicate support for twoHARQ-Processes-r14. This ensures the UE can handle the increased complexity of multiple TB scheduling efficiently.
