Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) for a wireless communication system. The UE determines at least one sidelink primary synchronization signal (S-PSS) sequence of at least one S-PSS signal. The at least one S-PSS sequence is different from a primary synchronization signal (PSS) sequence. The EE also determines at least one sidelink secondary synchronization signal (S-SSS) sequence of at least one S-SSS signal. The EE determines a plurality of S-PSS symbols and a plurality of S-SSS symbols corresponding to a sub carrier spacing (SCS). The EE transmits to another EE the determined plurality of S-SSS symbols after the determined plurality of S-PSS symbols. The SCS may be associated with a physical resource block (PRB) allocation size. A maximum of 11 PRBs for a sidelink synchronization signal block (S-SSB) may be set based on the SCS.
