Kind Code:
A1
Abstract:
The present invention provides a method by which first vehicle-to-X (V2X) user equipment (UE) for supporting distance measurement transmits a ranging response signal in a wireless communication system, the method comprising: receiving a ranging request signal from second V2X UE; and transmitting, to the second V2X UE, the ranging response signal as a response to the ranging request signal on the basis of distance measurement parameter information, wherein the distance measurement parameter information includes information on a cyclic prefix (CP) length used for the ranging response signal, and the CP length used for the ranging response signal is different from a CP length to be used in V2X data channel transmission.
