Classification: CPC H | IPC H

Claim 7:
8. An apparatus, comprising:
a processor configured to cause a user equipment device (UE) to:
receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot of a plurality of slots, the PDSCH further scheduled on a current component carrier (CC) of a plurality of CCs, wherein the plurality of CCs comprises different sub-carrier spacings, wherein the PDCCH comprises a downlink control information (DCI) that comprises:
a total downlink assignment index (DAI) for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback, wherein the total DAI is updated from scheduling instance to scheduling instance, and the total DAI indicates a number of scheduling instances up to a current scheduling instance in which PDSCH transmission(s) associated with PDCCH or PDCCH indicating that a downlink (DL) semi-persistent scheduling (SPS) release is present; and
a counter DAI based on an accumulative number of scheduling instances up to the current scheduling instance in which PDSCH transmission(s) associated with PDCCH or PDCCH indicating that a DL SPS release is present; and

transmit the HARQ-ACK feedback, wherein the HARQ-ACK feedback is formed in accordance with the total DAI and the counter DAI.
