1. A method performed by an integrated access and backhaul (IAB) node including an IAB distributed unit (DU) and an IAB mobile terminal (MT) in a wireless communication system, the method comprising:
receiving, by the IAB DU, configuration information on a symbol of the IAB DU via a F1 application protocol (F1AP) interface, from a central unit (CU) of a base station, wherein the symbol is configured as one of a hard, a soft, or unavailable; and
in case that a first resource block (RB) set is configured as a soft based on the configuration information, performing at least one of a transmission or a reception of a first signaling by the IAB DU on the first soft RB set,
wherein a transmission or a reception of a second signaling by the IAB MT on the first soft RB set is performed and not changed due to use of the first soft RB set by the IAB DU.
