1. A method, performed by a user equipment (UE), in a wireless communication system, the method comprising:
receiving, from a first transmit/receive point (TRP), downlink control information (DCI) in a physical downlink control channel (PDCCH), for a first physical downlink shared channel (PDSCH) and a second PDSCH, wherein the DCI is associated with the first TRP and a second TRP;
based on the DCI from the first TRP, determining a first physical uplink control channel (PUCCH) resource and a second PUCCH resource;
determining whether symbol-level overlapping exists between the first PUCCH resource and the second PUCCH resource;
in case that at least one symbol in a slot allocated to the first PUCCH resource does not overlap with at least one symbol in a slot allocated to the second PUCCH resource, generating a first HARQ-ACK codebook and a second HARQ-ACK codebook associated with the PDCCH;
transmitting, to the first TRP, the first HARQ-ACK codebook on the first PUCCH resource indicated by the DCI in the PDCCH; and
transmitting, to the second TRP, the second HARQ-ACK codebook on the second PUCCH resource indicated by the DCI in the PDCCH.
