1. A method of performing sidelink communications by a transmitting terminal, the method comprising:
receiving sidelink synchronization signal block (S-SSB) configuration information for sidelink communications; and
receiving an S-SSB in an S-SSB monitoring slot in accordance with the S-SSB configuration information,
wherein the S-SSB is comprised of a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH), and the S-PSS, the S-SSS, and the PSBCH are allocated to N number of consecutive symbols in the S-SSB monitoring slot,
wherein the S-SSB comprises two S-PSS symbols, two S-SSS symbols, and N−4 number of PSBCH symbols,
wherein, when the S-SSB monitoring slot is a normal cyclic prefix, the N is 13, and when S-SSB monitoring slot is an extended cyclic prefix, the N is 11, and the S-SSB is comprised of 132 subcarriers, and
wherein the S-SSB is configured such that the PSBCH is allocated to symbol index 0 in the S-SSB monitoring slot, the S-PSS is allocated to symbol indices 1 and 2 in the S-SSB monitoring slot, the S-SSS is allocated to symbol indices 3 and 4 in the S-SSB monitoring slot, and the PSBCH is allocated to symbol indices 5 to N−1 in the S-SSB monitoring slot.
