Question: What is a prerequisite for a User Equipment (UE) to support multiple TB scheduling in the uplink for FDD, specifically for npusch-MultiTB-r16?
Option 1: The UE must support at least one HARQ process.
Option 2: The UE must also indicate support of twoHARQ-Processes.
Option 3: The UE needs to be capable of only TDD operations.
Option 4: The UE has to be categorized as NB1 or higher.
Explanation: To ensure efficient handling of multiple TB scheduling, a UE supporting npusch-MultiTB-r16 must also be capable of managing increased complexity, which is facilitated by having at least two HARQ processes, hence the requirement for twoHARQ-Processes support. This directly impacts the UE's ability to handle concurrent transmissions and retransmissions efficiently in uplink scenarios.
