1. A method of correcting, by a first device, a position based on a first antenna and a second antenna distributed at a predetermined distance in a wireless communication system supporting sidelink, the method comprising:
receiving a first signal on the first antenna and the second antenna, wherein the first signal comprises information on a position of a second device on a first coordinate axis and a second coordinate axis; and
correcting a position of the first device based on the first signal,
wherein the first device determines a specific time at which the position of the first device corresponds to the position of the second device, based on a difference in reception times at which the first signal is received by the first antenna and the second antenna, and
wherein the first device corrects the position of the first device at the specific time on one coordinate axis specified by the first signal among the first coordinate axis and the second coordinate axis.
