An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for HARQ-ACK transmission in an NR network, the processing circuitry is to decode DCI received via a PDSCH. The DCI includes resource assignments, a set index, and a reset indicator for a set of PDSCHs. Downlink data associated with the set index and received via the set of PDSCHs using the resource assignments is decoded. A PUCCH is encoded for transmission to a base station to include a HARQ-ACK of the decoded downlink data associated with the set index. The PUCCH is encoded to further include a second HARQ-ACK for a prior PDSCH reception, when the prior PDSCH reception includes PDSCHs associated with the set index and the reset indicator matches a reset indicator of the prior PDSCH reception.
