1. A method performed by a child integrated access and backhaul (IAB) node including an IAB-mobile termination (MT) and an IAB-distributed unit (DU) in a wireless communication system including a parent IAB node and the child IAB node, the method comprising:
receiving, from the parent IAB node, information indicating a timing case to be applied for the child IAB node;
transmitting, to the parent IAB node, guard information associated with switching between timing cases including the indicated timing case;
setting an uplink transmission time of the IAB-MT to a transmission time of the IAB-DU in case that the indicated timing case is a first timing case; and
setting an uplink transmission time of the IAB-MT based on a timing advance (TA) applied for a user equipment (UE) in case that the indicated timing case is a second timing case.
