    摘要: A method and a device for supporting multicast transmission are disclosed. A terminal operating method comprises the steps of: receiving, from a base station, an RRC message indicating the activation of HARQ-ACK feedback; receiving, from the base station, a first DCI including information indicating deactivation of the HARQ-ACK feedback; receiving, from the base station, a first multicast PDSCH on the basis of first scheduling information included in the first DCI; generating a first HARQ-ACK bit for the first multicast PDSCH even if the first DCI indicates deactivation of the HARQ-ACK feedback; generating a HARQ codebook including the first HARQ-ACK bit; and transmitting, to the base station, the HARQ codebook through an uplink channel.

    摘要: A method for reporting sidelink HARQ response information, performed by a terminal, comprises the steps of: receiving, from a base station, information on allocation of a PSSCH resource for PSSCH transmission; determining a PSFCH resource for PSFCH reception corresponding to the PSSCH transmission; determining a transmission time point of HARQ response information corresponding to the PSSCH transmission; and transmitting the HARQ response information, corresponding to the PSSCH transmission, to the base station at the determined time point, wherein the transmission time point of the HARQ response information is expressed as a time offset, L, from a time point of the PSFCH resource, and information on the transmission time point of the HARQ response information may be transmitted from the base station to the terminal.
