Method and apparatus for transmitting hybrid automatic repeat and request information in a wireless communication system

A method performed by a base station in a communication system, the method comprising:

• transmitting, to a terminal, a configuration including first physical downlink shared channel (PDSCH) time resources associated with first type downlink control information (DCI) and second PDSCH time resources associated with second type DCI;
• and
• receiving, from the terminal, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information in an HARQ-ACK occasion,
• wherein the HARQ-ACK information is generated based on PDSCH reception occasions, which is determined based on removing a PDSCH time resource including an uplink symbol from the PDSCH reception occasion candidates, and
• wherein the PDSCH reception occasion candidates are associated with union of the first PDSCH time resources and the second PDSCH time resources.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, a configuration including first physical downlink shared channel (PDSCH) time resources associated with first type downlink control information (DCI) and second PDSCH time resources associated with second type DCI,
• identify PDSCH reception occasion candidates based on union of the first PDSCH time resources and the second PDSCH time resources,
• generate hybrid automatic repeat request-acknowledgement (HARQ-ACK) information based on PDSCH reception occasions, which is determined based on removing a PDSCH time resource including an uplink symbol from the PDSCH reception occasion candidates, and
• transmit, to the base station, the HARQ-ACK information.
