Abstract: A method and apparatus for performing a scheduling request for transmitting uplink data in a wireless communication system are provided. Specifically, a terminal receives allocation information for a first SR resource that is semi-statically allocated from a base station. The terminal receives allocation information for a second SR resource dynamically allocated from the base station. The second SR resource is additionally allocated in addition to the first SR resource for a buffer status report (BSR). At this time, the allocation information for the first SR resource comprises: mapping information between the first and second SR resources and buffer size information. The terminal transmits an SR to the base station through the first SR resource or the second SR resource.

Abstract: The present invention relates to a Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.
