摘要
Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.
