摘要： Apparatuses, methods, and systems are disclosed for triggering HARQ-ACK feedback for a downlink slot set. An apparatus includes a receiver that receives a first downlink control information (“DCI”) format from a base unit for triggering hybrid automatic repeat request acknowledgement (“HARQ-ACK”) feedback for a plurality of downlink transmissions, the HARQ-ACK feedback for the plurality of downlink transmissions multiplexed in a HARQ-ACK codebook. An apparatus includes a processor that identifies the plurality of downlink transmissions and determines a slot for transmitting the HARQ-ACK codebook based on the first DCI format. An apparatus includes a transmitter that transmits the HARQ-ACK codebook to the base unit in the slot.

摘要： 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.
