1. A method, comprising:
receiving, by an integrated access and backhaul (IAB) node including a distributed unit (DU) and a mobile terminal (MT), first configuration information for configuring a resource for an operation of the MT;
receiving, by the IAB node, second configuration information for configuring a resource for an operation of the DU; and
identifying, by the IAB node, a specific resource supporting simultaneous operation of the MT and the DU based on the first configuration information and the second configuration information,
wherein based on a type of a first signal that the MT intends to communicate in the specific resource and a type of a second signal that the DU intends to communicate in the specific resource, a multiplexing type to be applied to the specific resource is determined,
wherein based on a signal related to a physical random access channel (PRACH) transmitted by the MT or a sounding reference signal (SRS) being included as the type of the first signal, the multiplexing type to be applied to the specific resource is i) a first multiplexing type operating with time division multiplexing (TDM) for all transmission/reception combinations of the MT and the DU or ii) a second multiplexing type operating with TDM for transmission of the MT,
wherein based on a synchronization signal or a channel state information reference signal (CSI-RS) received by the MT being included as the type of the first signal, the multiplexing type to be applied to the specific resource is i) the first multiplexing type or ii) a third multiplexing type operating with TDM for reception of the MT; and
wherein a multiplexing type to be applied to the specific resource and a multiplexing type to be applied to another resource located after the specific resource are different from each other.
