8. A V2X (vehicle to everything) device for V2X sidelink, the device comprising:
at least one processor; and
at least one memory for storing instructions and operably electrically connectable with the at least one processor, based on the instructions being operated by the at least one processor, performed operation comprising:
performing a synchronization for a V2X sidelink transmission based on a synchronization reference user equipment (SyncRefUE); and
performing the V2X sidelink transmission based on the synchronization,
wherein for the V2X sidelink transmission, a transmission timing error (Te) is to be less than or equal to a first value,
wherein the first value is predetermined based on a subcarrier spacing (SCS) of a sidelink signal which includes 15 kHz, 30 kHz and 60 kHz,
wherein based on that the SCS of the sidelink signal is 60 kHz, the first value is a value obtained from 5*64*Tc, and
wherein the Tc is a basic time unit.
