1. A method performed by a first device in a wireless communication system, the method comprising:
obtaining configuration information related to a hybrid automatic repeat request (HARQ);
receiving, from a second device, first sidelink control information (SCI) for scheduling second SCI and a physical sidelink shared channel (PSSCH) on a physical sidelink control channel (PSCCH);
receiving, from the second device, the second SCI on the PSSCH;
transmitting, to the second device, a pre-emption message in a HARQ feedback resource based on the configuration information; and
transmitting, to the second device, the pre-emption message in a PSCCH resource after the HARQ feedback resource,
wherein the pre-emption message includes information related to a transmission of sidelink information by the first device.
