Abstract
The present application relates to a method and apparatus for fallback operation for a semi static HARQ-ACK codebook determination. One embodiment of the present disclosure provides an apparatus including a receiver that receives at least one downlink (DL) transmission within a DL association set. The apparatus also includes a processor that determines whether to use a fallback hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission and a transmitter that transmits a first HARQ-ACK codebook on a first resource for the DL association set in response to the fallback HARQ-ACK transmission being used or a second HARQ-ACK codebook on a second resource for the DL association set in response to the fallback HARQ-ACK transmission being used.
