Abstract: An embodiment of the present invention relates to a method for a vehicle-to-everything (V2X) terminal selecting resources and transmitting a physical sidelink shared channel (PSSCH) in a wireless communication system. The method, for transmitting a PSSCH, comprises the steps of: selecting a resource set, for transmission of a PSSCH, from a maximum transmission opportunity in a set and a resource reservation interval; and transmitting the PSSCH by means of the selected resource set. A resource set for retransmission of the PSSCH is selected from a time domain distance and the selected resource set. A maximum value of the time domain distance is variously configured for each TDD configuration configured to a V2X terminal.
