Disclosed are a method and a device for transmitting or receiving HARQ-ACK information in a wireless communication system. A method for transmitting HARQ-ACK information according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, first physical uplink control channel (PUCCH) configuration information related to an ACK/negative ACK (NACK)-based HARQ-ACK report for a multi-cast physical downlink shared channel (PDSCH) or second PUCCH configuration information related to an NACK-only-based HARQ-ACK report for the multi-cast PDSCH for each one or more uplink bandwidth parts (BWPs) configured for a terminal; receiving, from the base station, downlink control information (DCI) for scheduling of a first multi-cast PDSCH; receiving the first multi-cast PDSCH from the base station on the basis of the DCI; and transmitting, to the base station, first HARQ-ACK information for the first multi-cast PDSCH on a first PUCCH.
