Abstract: Provided are a method and a device for a terminal transmitting sidelink control information (SCI) in a wireless communication system. The method enables generating an SCI format and transmitting the generated SCI format to another terminal, wherein the SCI format is transmitted after determining the number of bits to be actually used in a resource allocation field included in the SCI format, and after zero-padding bits other than the number of bits to be actually used in the resource allocation field.
