User equipments and communication methods

A user equipment (UE), comprising:

• control unit configured to set a sidelink (SL) bandwidth part (BWP) configuration, the SL BWP configuration indicating a subcarrier spacing (SCS) to be used for a SL BWP;
• the control unit is further configured to determine a SCS for a SL-synchronization signals/physical sidelink broadcast channel (S-SS/PSBCH) block, wherein
• in a case that the SCS of the SL BWP is 15 kHz, the SCS for the S-SS/PSBCH block is determined as a first value,
• in a case that the SCS of the SL BWP is 30 kHz or 60 kHz, the SCS for the S-SS/PSBCH block is determined to be same as the SCS of the SL BWP;
• and
• reception unit configured to receive, from another UE, the S-SS/PSBCH block by using the determined SCS.

A communication method performed by a user equipment (UE), comprising:

• in a case that the SCS of the SL BWP is 30 kHz or 60 kHz, the SCS of the S-SS/PSBCH block is determined to be same as the SCS of the SL BWP;
• and
• transmitting, to another UE, the S-SS/PSBCH block by using the determined SCS in the SL BWP.
