1. A method for performing wireless communication by a first device, the method comprising:
mapping, by the first device, a first sidelink control information (SCI) to a resource related to a physical sidelink control channel (PSCCH);
mapping, by the first device, based on a remainder obtained by dividing a part of cyclic redundancy check (CRC) on the PSCCH by frequency density (KPT-RS) related to phase tracking-reference signal (PT-RS) mapping, a PT-RS to a resource related to a physical sidelink shared channel (PSSCH);
mapping, by the first device, a second SCI to a resource not used for transmission of the PT-RS among the resource related to the PSSCH; and
transmitting, by the first device, the first SCI, the second SCI, and the PT-RS to a second device.
