Systems and methods for reliable mac ce ack/nack confirmation

A method performed by a wireless device for transmitting feedback, the method comprising one or more of:

• being configured by a network node with at least one feedback enabled Hybrid Automatic Repeat Request, HARQ, process while remaining HARQ processes of the wireless device have the feedback disabled;
• receiving an indication of a number of slots, X, as part of a System Information Block, SIB, wherein X is specific to a delay associated with HARQ Acknowledgement/Negative Acknowledgement, ACK/NACK, feedback;
• receiving, from the network node, a first Physical Downlink Shared Channel, PDSCH, carrying a Medium Access Control, MAC, Control Element, CE, activation/deactivation command requiring a HARQ ACK/NACK feedback on a Physical Uplink Control Channel, PUCCH, using the at least one feedback enabled HARQ process;
• transmitting the HARQ ACK/NACK feedback on the PUCCH in a slot n corresponding to the first PDSCH on the PUCCH;
• determining a delay term via multiplying X by a number of slots per subframe for a subcarrier spacing, SCS, µ associated with the PUCCH;
• and
• assuming that the information related to the MAC CE activation/deactivation command is applied at the wireless device from a slot n′ where the slot n′ is after a delay given by the determined delay term from the slot n.
