Claim 3:
4. A second user equipment (UE) in a wireless communication system, the second UE comprising:
a transceiver configured to receive, from a first UE, a sidelink-synchronization signal and physical broadcast channel block (S-SSB) including a sidelink-primary synchronization signal (S-PSS), a sidelink-secondary synchronization signal (S-SSS), a physical sidelink broadcast channel, PSBCH, and a demodulation reference signal (DMRS) for the PSBCH over a sidelink channel; and
a processor operably connected to the transceiver, the processor configured to:
identify, from the S-SSB, the S-PSS, the S-SSS, the PSBCH, and the DMRS for the PSBCH, wherein the S-PSS is defined based on a first sequence and the S-SSS is defined based on a second sequence;

wherein the S-SSB includes two symbols for the S-PSS and two symbols for the S-SSS,
wherein the first sequence for the S-PSS is defined by:, d_SSSS
