1. A method comprising:
receiving, by a terminal from a network, at least one physical downlink shared channel (PDSCH); and
transmitting, by the terminal to the network, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information,
wherein, for the HARQ-ACK information associated only with a second HARQ-ACK reporting mode and for more than one HARQ-ACK information bit;
a physical uplink control channel (PUCCH) resource is determined from a first PUCCH configuration information for multicast related to a first HARQ-ACK reporting mode, based on the first PUCCH configuration information being provided,
the second HARQ-ACK reporting mode corresponds to a reporting mode that HARQ-ACK information including only ACK values is not transmitted and HARQ-ACK information including a non-acknowledgement (NACK) value is transmitted, and
the first HARQ-ACK reporting mode corresponds to a reporting mode that an ACK value or a NACK value based on whether a transport block of the at least one PDSCH being successfully decoded or not is generated.
