Proposed is a signal transmission method performed in a wireless communication system by an integrated access and backhaul (IAB) node, the method being characterized by comprising: receiving first information about a first timing and second information about a second timing; and transmitting a first signal and a second signal to a parent node of the IAB node, wherein the first signal is transmitted on a first resource, and the second signal is transmitted on a second resource. The first resource is a time resource to which the first timing is applied, and the second resource is a time resource to which the second timing is applied.
