1. A method performed by a user equipment (UE), the method comprising:
receiving first downlink control information (DCI) scheduling one or more physical downlink shared channels (PDSCHs), wherein the first DCI includes a PDSCH group index and a hybrid automatic repeat and request (HARQ) feedback timing indicator;
identifying a value of the HARQ feedback timing indicator included in the received first DCI, wherein a slot for HARQ feedback transmission is determined based on the value of the HARQ feedback timing indicator and a slot where a last PDSCH among the one or more PDSCHs is transmitted; and
in case that the value is identified as −1, transmitting HARQ feedback information for the one or more PDSCHs on a slot indicated based on a value of a HARQ feedback timing indicator included in a second DCI in which a PDSCH group index is equal to the PDSCH group index of the first DCI.
