1. A method of configuring hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for physical downlink shared channel (PDSCH) transmission in wireless communication, the method comprising:
receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure a one-shot HARQ-ACK feedback;
receiving, by the UE, a medium access control (MAC) control element (CE) indicating a list of activated serving cells;
receiving, by the UE, a downlink control information (DCI) comprising a one-shot request field with a positive value, wherein the DCI triggers a one-shot HARQ-ACK codebook determined by the UE according to the list of activated serving cells indicated by the MAC CE; and
transmitting, by the UE, a one-shot HARQ-ACK feedback for the list of activated serving cells,
wherein, in response to that the UE has previously transmitted HARQ-ACK information for a transport block (TB) t for a HARQ process number h on a serving cell c, and has not been scheduled for reception of another PDSCH corresponding to the TB t for the HARQ process number h on the serving cell c since a previous HARQ-ACK report, the UE does not report HARQ-ACK information for the HARQ process number h on the serving cell c in the one-shot HARQ-ACK codebook.
