1. A method performed by a user equipment (UE) in a communication system, the method comprising:
receiving, via higher layer signaling, a time domain bundling configuration to enable bundling corresponding to a logical AND operation for a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook;
receiving, via the higher layer signaling, a time domain duplex (TDD) configuration;
receiving downlink control information (DCI) including information indicating a row including more than one starting and length values (SLIVs) of a time domain resource allocation (TDRA) table;
determining candidate physical downlink shared channel (PDSCH) reception occasions for the semi-static HARQ-ACK codebook;
determining a HARQ-ACK information bit in the semi-static HARQ-ACK codebook associated with a candidate PDSCH reception occasion based on performing the logical AND operation of HARQ-ACK information bits corresponding to a plurality of PDSCHs, wherein the plurality of PDSCHs, that do not overlap with an uplink (UL) symbol identified by the TDD configuration, are scheduled by the DCI; and
transmitting the semi-static HARQ-ACK codebook.
