The method includes transmitting a resource set associated with an SSB within a subframe or slot, and the SSB includes a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and 0 to 1 physical sidelink broadcast channel (PSBCH) between the S-PSS and S-SSS. ## Claims ### Claim 1 A user equipment for transmitting a synchronization signal block (SSB), comprising: a memory; a transceiver; and a processor coupled to the memory and the transceiver; wherein the processor is configured to control the transceiver to transmit an SSB by using a resource set within a subframe or slot, wherein the SSB comprises a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH), and the resource set comprises two orthogonal frequency division multiplexing (OFDM) symbols used for the S-PSS, two OFDM symbols used for the S-SSS, more than 1 OFDM symbol used for the PSBCH, and 0 to 1 OFDM symbol within the OFDM symbols used for the PSBCH is between the OFDM symbols for the S-PSS and the S-SSS, and positions of the OFDM symbols used for the S-PSS are in front of positions of the OFDM symbols used for the S-SSS. ### Claim 2 (depends on 1) The user equipment of claim 1, wherein the two OFDM symbols used for the S-PSS are adjacent OFDM symbols. ### Claim 3 (depends on 1) The user equipment of claim 1, wherein the two OFDM symbols used for the S-SSS are adjacent OFDM symbols. ### Claim 4 (depends on 1) The user equipment of claim 1, wherein a first OFDM symbol used for the PSBCH after the OFDM symbol used for the S-PSS comprises resources used for DMRS which is configured to decode the PSBCH. ### Claim 5 (depends on 1) The user equipment of claim 1, wherein a symbol in front of the S-PSS is mapped with the PSBCH. ### Claim 6 (depends on 1) The user equipment of claim 1, wherein the SSB further comprises an automatic gain control (AGC) symbol positioned in front of the S-PSS. ### Claim 7 (depends on 6) The user equipment of claim 6, wherein the AGC symbol is mapped with the PSBCH or configured to pad bits. ### Claim 8 (depends on 1) The user equipment of claim 1, wherein the SSB is located at a frequency center of a carrier or a frequency location of the SSB is pre-configured or configured by a network. ### Claim 9 (depends on 1) The user equipment of claim 1, wherein a position of the SSB in a time domain is pre-configured or configured by a network. ### Claim 10 (depends on 1) The user equipment of claim 1, wherein a periodicity of the SSB is pre-configured or configured by a network. ### Claim 11 (depends on 1) The user equipment of claim 1, wherein frequency resources of the S-PSS and the S-SSS are same. ### Claim 12 A method for transmitting a synchronization signal block (SSB) of a user equipment, comprising: transmitting an SSB by using a resource set within a subframe or slot, wherein the SSB comprises a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH), and the resource set comprises two orthogonal frequency division multiplexing (OFDM) symbols used for the S-PSS, two OFDM symbols used for the S-SSS, more than 1 OFDM symbol used for the PSBCH, and 0 to 1 OFDM symbol within the OFDM symbols used for the PSBCH is between the OFDM symbols for the S-PSS and the S-SSS, and positions of the OFDM symbols used for the S-PSS are in front of positions of the OFDM symbols used for the S-SSS. ### Claim 13 (depends on 12) The method of claim 12, wherein the two OFDM symbols used for the S-PSS are adjacent OFDM symbols. ### Claim 14 (depends on 12) The method of claim 12, wherein the two OFDM symbols used for the S-SSS are adjacent OFDM symbols. ### Claim 15 (depends on 12) The method of claim 12, wherein a first OFDM symbol used for the PSBCH after the OFDM symbol used for the S-PSS comprises resources used for DMRS which is configured to decode the PSBCH. ### Claim 16 (depends on 12) The method of claim 12, wherein a symbol in front of the S-PSS is mapped with the PSBCH. ### Claim 17 (depends on 12) The method of claim 12, wherein the SSB further comprises an automatic gain control (AGC) symbol positioned in front of the S-PSS. ### Claim 18 (depends on 17) The method of claim 17, wherein the AGC symbol is mapped with the PSBCH or configured to pad bits. ### Claim 19 (depends on 12) The method of claim 12, wherein the SSB is located at a frequency center of a carrier or a frequency location of the SSB is pre-configured or configured by a network. ### Claim 20 (depends on 12) The method of claim 12, wherein a position of the SSB in a time domain is pre-configured or configured by a network. ### Claim 21 (depends on 12) The method of claim 12, wherein a periodicity of the SSB is pre-configured or configured by a network. ### Claim 22 (depends on 12) The method of claim 12, wherein frequency resources of the S-PSS and the S-SSS are same.
