Patent ID: 11489635

Abstract:
The present disclosure is related to a method and apparatus for determining a dynamic hybrid automatic repeat request-acknowledge (HARQ-ACK) codebook. A method for determining a dynamic HARQ-ACK codebook for includes receiving a plurality of downlink (DL) transmissions, wherein each DL transmission has an associated first signal indicating whether the DL transmission is a last transmission of the plurality of DL transmissions. The method further includes transmitting a HARQ-ACK codebook corresponding to the plurality of DL transmissions, wherein, based on the first signal, HARQ-ACK feedback for the last transmission of the plurality of DL transmissions is arranged at the end of the HARQ-ACK codebook. The present disclosure reduces signaling overhead for a dynamic HARQ-ACK codebook and avoids misunderstanding between a base unit and a remote unit when determining the dynamic HARQ-ACK codebook.
