receiving, from one or more second devices, one or more control channels;

receiving, from the one or more second devices, one or more shared channels related to the one or more control channels; and

performing one or more hybrid automatic repeat request (HARQ) processes related to the one or more shared channels with the one or more second devices,

wherein, based on a generation of a new sidelink packet while the one or more HARQ processes are maintained, a HARQ process among the one or more HARQ processes is terminated, and

wherein the HARQ process is a randomly selected HARQ process, a HARQ process with a fewest number of receptions, a HARQ process with a lowest priority, or a HARQ process with a lower priority than a priority related to the new sidelink packet.
