1. A method for performing, by a first device, sidelink (SL) communication, the method comprising:
transmitting, to a second device, sidelink control information (SCI) based on a first physical sidelink control channel (PSCCH);
transmitting, to the second device, an aperiodic sidelink channel state information-reference signal (SL CSI-RS) based on a first physical sidelink shared channel (PSSCH) related to the first PSCCH; and
receiving, from the second device, channel state information obtained based on the aperiodic SL CSI-RS,
wherein the aperiodic SL CSI-RS is transmitted only in a resource used for the first PSSCH related to the first PSCCH.
