Abstract: A method of wireless communication by an integrated access and backhaul network (IAB) donor transmits a configuration message on a source path to a first IAB node via a first distributed unit of the IAB donor. The method also instructs the first IAB node to delay delivery of the configuration message to a second node. The method migrates at least part of communications to the first IAB node from the source path to a target path via a second distributed unit. Another method of wireless communication is executed by a first integrated access and backhaul network (IAB) node. The method receives a first configuration message over a source path to a first IAB donor via a first distributed unit of the first IAB donor. The method also delays delivery of the first configuration message to a second node until a trigger occurs.

Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node in a wireless multi-hop network may determine a change in multiplexing capability relating to communications on one or more radio link control (RLC) channels, and transmit information to a central unit that enables the central unit to cause modification of at least one of routing or RLC channel mapping in the wireless multi-hop network based at least in part on the change in multiplexing capability. Numerous other aspects are provided.

Abstract: A wireless node in a wireless multi-hop network may transmit, based at least in part on a change in multiplexing capability relating to communications on one or more radio link control (RLC) channels, information to at least one of a parent node or a child node that enables the at least one of the parent node or the child node to prioritize communications with the wireless node. The wireless node may transmit or receive communications prioritized according to the information with the at least one of the parent node or the child node.

Abstract: An integrated access and backhaul (IAB) node may receive a parent knowledge message, the parent knowledge message indicating whether a parent IAB node of the child IAB node has received an optional signaling message, determining to transition between first resources and second resources at a transition time, the first resources being associated with use of a mobile termination of the child IAB node, the second resources being associated with use of the distributed unit of the child IAB node, and determine a number of guard symbols provided by the parent IAB node at the transition time based on whether the parent knowledge message indicates that the parent IAB node has received the optional signaling message.

Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. In an example, the aspects include determining, by a central unit (CU), a configuration of not-available (NA) resources for a parent node, wherein the NA resources of the parent node correspond to a set of one or more resources configured at the parent distributed unit (DU) as being unavailable for uplink and downlink communications between the parent DU and a child node; determining, by the CU, a first child DU resource configuration, wherein the child DU resource configuration corresponds to a set of one or more resources configured at the child DU for uplink or downlink communications between the child node and at least one child of the child node; modifying, by the CU, the first child DU resource configuration to create a modified child DU resource configuration.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). Certain aspects provide a method for wireless communications. The method generally includes determining, at a first wireless node, a priority value associated with the first wireless node configured to serve one or more child nodes, determining occurrence of interference to communications of the first wireless node and/or a second wireless node, and taking one or more actions in response to the determination of the interference based on the priority value.

Abstract: Aspects described herein relate to quasi co-location (QCL) indications in an integrated access and backhaul (IAB) system. In an example, an IAB node may determine a spatial relation between a first communication of a DU entity and a second communication of one of the DU entity or a co-located MT entity. The IAB node may further configure a beam of at least one of the MT or the DU based on the determined spatial relation. The IAB node may further communicate using the beam with at least one entity.

Abstract: Aspects of the present disclosure provide techniques for beam and cell selection based on power configuration of a wireless node (e.g., an Integrated Access and Backhaul (IAB) node). In some cases, the node monitors synchronization signal block (SSB) transmissions from one or more network entities, and selects a beam or cell based on the monitoring and one or more metrics designed to limit potential interference caused by uplink transmissions from the first node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity in an integrated access and backhaul (IAB) network may determine that a trigger condition for updating transport network layer information of an IAB node in the IAB network is satisfied, based at least in part on at least one of: a change of a donor distributed unit associated with the IAB node, a central entity change associated with the IAB node, or an establishment, release, or modification of a route including the IAB node; and provide, to the IAB node, updated transport network layer information, based at least in part on the trigger condition being satisfied. Numerous other aspects are described.
