Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A first user equipment (UE) in a wireless communication system, the first UE comprising:
a processor configured to:
identify a sidelink-primary synchronization signal (S-PSS) and a sidelink-secondary synchronization signal (S-SSS), wherein the S-PSS is defined based on a first sequence and the S-SSS is defined based on a second sequence, and
identify a physical sidelink broadcast channel (PSBCH) and a demodulation reference signal (DMRS) for the PSBCH; and

a transceiver operably coupled to the processor, the transceiver configured to transmit, to a second UE, a sidelink-synchronization signal and physical broadcast channel block (S-SSB) including the S-PSS, the S-SSS, the PSBCH, and the DMRS for the PSBCH,
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_SPSS(n)=1−2*x(m), m=(n+43*N_GID{circumflex over ( )}SL+22) mod 127, 0 n<127,
wherein N_GID{circumflex over ( )}SL is a sidelink synchronization identity and N_GID{circumflex over ( )}SL is 1 or 0,
wherein a length of the first sequence is 127, and
wherein a length of the second sequence is 127.
