Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems include configuring one or more resources to allocate time-domain or frequency domain availability/utilization. Configurations of resources can be aligned between one or more nodes such that resource availability of a first node can be coupled to resources of a second node. Allocated resources can include uplink, downlink, and flexible resources. Allocated resources can be indicated as not available, hard, or soft resource types. A configuration pattern can indicate a sequence of time-domain resource or frequency domain resource availability of a DU in the IAB network.
