Harq rtt timer adjustment for multi-tb scheduling

A method of operating a wireless device in a communication network, the method comprising:

• receiving a scheduling message including a Downlink Control Indication, DCI, that includes a schedule identifying a plurality of transmission blocks, TBs;
• determining a quantity of the plurality of TBs that are identified in the DCI;
• determining a quantity of Hybrid Automatic Repeat Request Acknowledgement, HARQ ACKs in an ACK bundle identified in the DCI;
• and
• dynamically generating an acknowledgement timer value that corresponds to the quantity of the plurality of TBs and the quantity of HARQ ACKs in the ACK bundle, characterized in that the acknowledgement timer value comprises a Hybrid Automatic Repeat Request Round Trip Time, HARQ RTT, timer value that is generated as 7+N*m in which N is a Physical Uplink Control Channel, PUCCH, repetition factor, and m is the number of HARQ ACK bundles identified in the scheduling message.

A wireless device adapted to perform the following steps:

• receiving a scheduling message including a Downlink Control Indication, DCI, that includes a schedule identifying a plurality of transmission blocks, TBs;
• determining a quantity of the plurality of TBs that are identified in the DCI;
• determining a quantity of Hybrid Automatic Repeat Request Acknowledgement, HARQ ACKs in an ACK bundle identified in the DCI;
• and
• dynamically generating an acknowledgement timer value that corresponds to the quantity of the plurality of TBs and the quantity of HARQ ACKs in the ACK bundle, characterized in that the acknowledgement timer value comprises a Hybrid Automatic Repeat Request Round Trip Time, HARQ RTT, timer value that is generated as 7+N*m in which N is a Physical Uplink Control Channel, PUCCH, repetition factor, and m is the number of HARQ ACK bundles identified in the scheduling message.

A method in a communication network system, comprising a radio access network, RAN, node and a wireless device, the method comprising:

• sending, by the RAN node to the wireless device, a scheduling message including a Downlink Control Indication, DCI, that includes a schedule identifying a plurality of transmission blocks, TBs;
• receiving, by the wireless device from the RAN node, the scheduling message including the DCI;
• determining, by the wireless device, a quantity of the plurality of TBs that are identified in the DCI;
• determining, by the wireless device, a quantity of Hybrid Automatic Repeat Request Acknowledgement, HARQ ACKs in an ACK bundle identified in the DCI;
• and
• dynamically generating, by the wireless device, an acknowledgement timer value that corresponds to the quantity of the plurality of TBs and the quantity of HARQ ACKs in the ACK bundle,
• characterized in that the acknowledgement timer value comprises a Hybrid Automatic Repeat Request Round Trip Time, HARQ RTT, timer value that is generated as 7+N*m in which N is a Physical Uplink Control Channel, PUCCH, repetition factor, and m is the number of HARQ ACK bundles identified in the DCI.
