摘要
Apparatuses, methods, and systems are disclosed for determining a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook. One apparatus includes a processor and a memory that stores code executable by the processor. The code, in various embodiments, determines a set of aggregated serving cells. The code groups the aggregated serving cells into a set of cell groups. In a further embodiment, the code determines, for an uplink subframe, a set of subframes for which a corresponding HARQ-ACK is to be transmitted in the uplink subframe. The code receives a cell-domain downlink assignment indicator and a cell-domain total assignment indicator in each downlink control information scheduling a physical downlink shared channel. The code additionally determines a HARQ-ACK codebook for each combination of a cell group and a subframe. The apparatus may include a transmitter that receives the downlink control information.
