Abstract

The present invention relates to a method and apparatus for SL PRS transmission for SL positioning. An operation method of a first device 100 in a wireless communication system is proposed. The method can include generating a SL PRS for positioning of the first device 100, spreading the first SL PRS into a plurality of first sub-SL PRSs, transmitting the plurality of first sub-SL PRSs based on a plurality of SL resources different from each other, and performing positioning of the first device 100 based on the plurality of first sub-SL PRSs.
