Systems and methods of HARQ codebook determination for multiple PUCCH

A method performed by a wireless device for enabling feedback for multiple Physical Downlink Shared Channel, PDSCH, transmissions, the method comprising:

• receiving, from a base station, a semi-static Hybrid Automatic Repeat Request, HARQ, codebook for each of multiple Physical Uplink Control Channel, PUCCH, resources in an uplink slot, each of the multiple PUCCH resources carrying HARQ feedback for Physical Downlink Shared Channel, PDSCH, transmissions within a certain downlink time interval, wherein each semi-static HARQ codebook is constructed based on remaining entries in a pruned sub-Time Domain Resource Allocation, TDRA, table, the sub-TDRA table being determined for one of the downlink time intervals to comprise entries of a TDRA table with a TDRA ending in the downlink time interval, the TDRA table being configured for the wireless device;
• and the pruned sub-TDRA table being pruned to remove entries with overlapping TDRAs;
• and
• transmitting, to the base station, feedback for multiple PDSCH transmissions based on the received semi-static HARQ codebooks.

A base station for constructing, for a wireless device, a semi-static Hybrid Automatic Repeat Request, HARQ, codebook for each of multiple Physical Uplink Control Channel, PUCCH, resources in an uplink slot, each of the multiple PUCCH resources carrying HARQ feedback for Physical Downlink Shared Channel, PDSCH, transmissions within a certain downlink time interval, the base station comprising:

• one or more processors;
• and
• memory comprising instructions to cause the base station to:
• based on a Time Domain Resource Allocation, TDRA, table comprising a list of TDRA entries configured for the wireless device, determine a sub-TDRA table for each downlink time interval comprising entries of the TDRA table with a TDRA ending in the downlink time interval;
• prune each sub-TDRA table to remove entries with overlapping TDRAs;
• construct a semi-static HARQ codebook for each pruned sub-TDRA table based on the remaining entries in the pruned sub-TDRA tables;
• and
• transmit the semi-static HARQ codebooks to the wireless device.

A wireless device for enabling feedback for multiple Physical Downlink Shared Channel, PDSCH, channels, the wireless device comprising:

• one or more processors;
• and
• memory storing instructions executable by the one or more processors, whereby the wireless device is operable to:
• receive, from a base station, a semi-static Hybrid Automatic Repeat Request, HARQ, codebook for each of multiple Physical Uplink Control Channel, PUCCH, resources in an uplink slot, each of the multiple PUCCH resources carrying HARQ feedback for Physical Downlink Shared Channel, PDSCH, transmissions within a certain downlink time interval;
• where each semi-static HARQ codebook is constructed based on remaining entries in a pruned sub-Time Domain Resource Allocation, TDRA, table, the sub-TDRA table being determined for one of the downlink time intervals to comprise entries of a TDRA table with a TDRA ending in the downlink time interval, the TDRA table being configured for the wireless device;
• and the pruned sub-TDRA table being pruned to remove entries with overlapping TDRAs;
• and
• transmit, to the base station, feedback for multiple data channels based on the semi-static HARQ codebook.
