Setting HARQ timing for PDSCH with pending PDSCH-to-HARQ-timing-indicator

A method, performed by a base station, the method comprising:

• determining a Physical Downlink Shared Channel, PDSCH-to-Hybrid Automatic Repeat Request, HARQ-timing for an upcoming Downlink, DL, data transmission to a User Equipment, UE;
• determining that HARQ feedback for the upcoming DL data transmission should be delayed by the UE until further notification from the base station;
• transmitting, to the UE, a first Downlink Control Information, DCI, associated with the upcoming DL data transmission, the first DCI comprising a first PDSCH-to-HARQ-timing-indicator value for indicating to the UE that the HARQ feedback for the upcoming DL data transmission should be delayed until further notification from the base station;
• and
• transmitting, to the UE, a second DCI as the further notification, the second DCI being associated with a second DL data transmission and comprising a numerical PDSCH-to-HARQ-timing-indicator.

A wireless device comprising processing circuitry configured to:

• receive a first Downlink Control Information, DCI, associated with a first Downlink, DL, data transmission, the first DCI comprising a Physical Downlink Shared Channel, PDSCH-to-Hybrid Automatic Repeat Request, HARQ-timing-indicator having a first value indicating that HARQ feedback for the first DL data transmission is to occur once the wireless device has received a DCI comprising a numerical PDSCH-to-HARQ-timing-indicator having a value different from the first value;
• receive the first DL data transmission;
• receive a second DCI associated with a second DL data transmission, the second DCI comprising a numerical PDSCH-to-HARQ-timing-indicator indicating a location in time for HARQ feedback associated with the second DL data transmission;
• and
• transmit a HARQ feedback associated with the first DL data transmission at the same location in time as that of HARQ feedback associated with the second DL data transmission.
