Abstract: The present specification provides a method for resource allocation for multiple traffic types in a wireless communication system supporting vehicle-to-everything (V2X) communication. The resource allocation method, which is performed by a base station, comprises the steps of: setting a specific resource pool including at least one resource for each traffic type, wherein each of the plurality of traffic types differs in at least one of a transmission period and transmission time interval (TTI) length; and transmitting the set specific resource pool to a terminal corresponding to each traffic type, wherein the specific resource pool is set on the basis of the number of the traffic types and the longest set TTI length. Accordingly, the resource allocation method proposed in the present specification can provide efficiency in use of resources.
