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 from a central unit (CU) of a base station via a F1 application protocol (F1AP) interface, configuration information on a symbol of the IAB DU, wherein the symbol for a resource block (RB) set is configured as one of hard, soft, or unavailable; and
in case that a first RB set is configured as soft based on the configuration information, performing, by the IAB DU, a transmission or a reception on the first RB set, and performing, by the IAB MT, a transmission or a reception on the first RB set,
wherein the transmission or the reception by the IAB MT is not changed due to use of the first RB set by the IAB DU.
