Method and device for transmitting or receiving hybrid automatic repeat request acknowledgment information in wireless communication system

A terminal in a wireless communication system, the terminal comprising:

• at least one transceiver;
• and
• at least one processor connected to the at least one transceiver,
• wherein the at least one processor is configured to:
• generate N (N>1) hybrid automatic repeat and request-acknowledgement (HARQ-ACK) information bits related to a second HARQ-ACK report mode;
• and
• transmit, through the at least one transceiver to a network, HARQ-ACK information, in one physical uplink control channel (PUCCH) with applying one of a first scheme according to a first HARQ-ACK report mode, or a second scheme by selecting one PUCCH resource among PUCCH resource sets based on values of the N HARQ-ACK information bits,
• wherein one of the first scheme or the second scheme is applied based on a configuration by the network.

A base station in a wireless communication system, the base station comprising:

• at least one transceiver;
• and
• at least one processor connected to the at least one transceiver,
• wherein the at least one processor is configured to:
• transmit, through the at least one transceiver, to a terminal, at least one of at least one multicast DCI format or at least one multicast physical downlink shared channel (PDSCH);
• and
• for N (N>1) hybrid automatic repeat and request-acknowledgement (HARQ-ACK) information bits related to a second HARQ-ACK report mode generated based on at least one of the at least one DCI format or the at least one multicast PDSCH, receive, through the at least one transceiver, from the terminal, in one physical uplink control channel (PUCCH), HARQ-ACK information to which one of a first scheme according to a first HARQ-ACK report mode, or a second scheme by selecting one PUCCH resource among PUCCH resource sets based on values of the N HARQ-ACK information bits is applied,
• wherein one of the first scheme or the second scheme is applied based on a configuration by the network.
