A method of transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) information by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a network, a first physical downlink shared channel (PDSCH) based on a first HARQ-ACK reporting mode; receiving, from the network, a second PDSCH based on a second HARQ-ACK reporting mode; and transmitting, to the network, the HARQ-ACK information based on a sequence in which a first bit corresponds to the first HARQ-ACK reporting mode and a second bit corresponds to the second HARQ-ACK reporting mode. ## Claims ### Claim 1 A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a network, a physical downlink control channel (PDCCH) on a first bandwidth part (BWP) based on a first group-radio network temporary identifier (G-RNTI) or a second G-RNTI; and receiving, from the network, a group common physical downlink shared channel (PDSCH) based on the PDCCH, wherein the first G-RNTI is configured for a multicast group common scheduling, and the second G-RNTI is configured for a broadcast group common scheduling, and wherein a BWP-inactivity timer is started or restarted based on the PDCCH addressed to the first G-RNTI configured for the multicast group common scheduling. ### Claim 2 (depends on 1) The method of claim 1, wherein: a BWP switching to a second BWP is performed based on an expiry of the BWP- inactivity timer. ### Claim 3 (depends on 2) The method of claim 2, wherein: the first BWP is an active BWP, and the second BWP is an initial BWP or a default BWP. ### Claim 4 (depends on 1) The method of claim 1, wherein: a data-inactivity timer is started or restarted based on a medium access control service data unit (MAC SDU) related to the multicast group common scheduling. ### Claim 5 (depends on 4) The method of claim 4, wherein: based on an expiry of the data-inactivity timer in an radio resource control (RRC) connected state, an action upon going to an RRC idle state is performed. ### Claim 6 (depends on 1) The method of claim 1, wherein: the PDCCH corresponds to a first type downlink control information (DCI) format or a second type DCI format, the first type DCI format is cyclic redundancy check (CRC) scrambled by the first G-RNTI configured for the multicast group common scheduling, and schedules the PDSCH reception, and the second type DCI format is CRC scrambled by the second G RNTI configured for the broadcast group common scheduling, and schedules the PDSCH reception. ### Claim 7 (depends on 1) The method of claim 1, wherein: the BWP-inactivity timer is not started and not restarted based on the PDCCH addressed to a-the second G-RNTI configured for the broadcast group common scheduling. ### Claim 8 (depends on 4) The method of claim 4, wherein: the data-inactivity timer is not started and not restarted based on a MAC SDU related to the broadcast group common scheduling. ### Claim 9 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: receive, from a network through the at least one transceiver, a physical downlink control channel (PDCCH) on a first bandwidth part (BWP) based on a first group-radio network temporary identifier (G-RNTI) or a second G-RNTI; and receive, from the network through the at least one transceiver, a group common physical downlink shared channel (PDSCH) based on the PDCCH, wherein the first G-RNTI is configured for a multicast group common scheduling, and the second G-RNTI is configured for a broadcast group common scheduling, and wherein a BWP-inactivity timer is started or restarted based on the PDCCH addressed to the first G-RNTI configured for the multicast group common scheduling. ### Claim 10 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, to at least one terminal through the at least one transceiver, a physical downlink control channel (PDCCH) on a first bandwidth part (BWP) based on a first group-radio network temporary identifier (G-RNTI) or a second G-RNTI; and transmit, to the at least one terminal through the at least one transceiver, a group common physical downlink shared channel (PDSCH) based on the PDCCH, wherein the first G-RNTI is configured for a multicast group common scheduling, and the second G-RNTI is configured for a broadcast group common scheduling, and wherein a BWP-inactivity timer is started or restarted based on the PDCCH addressed to the first G-RNTI configured for the multicast group common scheduling.
