Abstract

Provided are a method by which a transmission terminal performs groupcast transmission in a wireless communication system, and a device. The method transmits a synchronization signal block (SSB) through an SSB beam, receives, from each of a plurality of terminals, a discovery message as a response to the SSB, determines a groupcast transmission timing for specific terminals from among the plurality of terminals on the basis of the discovery message, transmits, to the specific terminals, a group transmission/reception timing message indicating the groupcast transmission timing, and performs groupcast transmission for the specific terminals by using the SSB beam at the groupcast transmission timing.
