1. A method performed by an integrated access and backhaul (IAB) node, comprising:
receiving indication information from a parent node of the IAB node via group common downlink control information (DCI) signaling, the indication information indicating at least one frequency domain resource of an operating band associated with one of a parent link between the IAB node and the parent node or a child link between the IAB node and a child node of the IAB node;
receiving, via radio resource control (RRC) signaling, a duration during which the indication information of the at least one frequency domain resource is applied; and
determining a set of frequency domain resources for the child link from the operating band at least based on the indication information.
