Question: How does the gNB provide the UE with HARQ-ACK feedback timing in Asynchronous Incremental Redundancy Hybrid ARQ?
Option 1: Only dynamically in the DCI
Option 2: Only semi-statically in an RRC configuration
Option 3: Both dynamically in the DCI and semi-statically in an RRC configuration
Option 4: Through a separate HARQ-ACK feedback channel
Explanation: The gNB provides the UE with HARQ-ACK feedback timing either dynamically in the Downlink Control Information (DCI) or semi-statically in a Radio Resource Control (RRC) configuration, allowing for flexible and efficient HARQ-ACK feedback transmission.
