    Abstract: A network management function of a relay network may identify relay node support of multi-mobile terminal (MT) operation, and may coordinate configuration of multiple backhaul links supported by the relay node via the multi-MT functionality of the relay node. In some cases, a relay node may transmit MT capabilities to the management function over a first established backhaul link, and the management function may configure a second backhaul link using a second MT function of the relay node. In other cases, the relay node may autonomously establish multi-MT connectivity based on preconfigured parent-selection policies, and the network management function may identify the relay node is dual-connected to the network management function. In either case, the network management function may configure backhaul routes (e.g., backhaul links) and resource configuration across the redundant topology.

    Abstract: Aspects relate to an integrated access backhaul (IAB)-Distributed Unit (DU) resource configuration framework for paired (e.g., frequency division duplex (FDD)) spectrum. Two DU resource configurations per cell may be supported for paired spectrum, including one for a first spectrum band (e.g., a downlink frequency band) and another for a second spectrum band (e.g., an uplink frequency band) of the paired spectrum. Each DU resource configuration may include a respective symbol pattern of symbol types (e.g., downlink (DL), uplink (UL), flexible) for a plurality of slots, as well as a corresponding availability attribute for each symbol type (e.g., hard, soft, or not available). A DU of an IAB node in an IAB network may receive the two DU resource configurations for the paired spectrum from a central unit (CU) of an IAB donor node in the IAB network.
