1. A method for performing wireless communication by a first device, the method comprising:
receiving information related to a first symbol for transmission of a channel state information-reference signal (CSI-RS);
determining whether to transmit the CSI-RS on the first symbol, based on the information related to the first symbol and information related to a second symbol for transmission of a physical sidelink shared channel (PSSCH);
transmitting, to a second device, first sidelink control information (SCI) based on a resource related to a physical sidelink control channel (PSCCH); and
transmitting, to the second device, second SCI including information related to a channel state information (CSI) request based on a resource related to the PSSCH.
