Abstract: An integrated access and backhaul (IAB) donor central unit (CU) may transmit, to an IAB-node, a plurality of messages for a child of the IAB-node, the plurality of messages including a first message being associated with a first condition, and a second message being associated with a second condition, and transmit an indication instructing the IAB to forward, to the child, the first message if a first condition is met or the second message if a second condition is met. The IAB-node may receive, from the IAB-donor-CU, the indication, determine that one condition among the first condition and the second condition has occurred, forward one of the first message or the second message to the child based on the occurrence of the one condition, and discard the other of the first message or the second message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit, to a second network node, a request for one or more intended time division duplex (TDD) configurations for one or more cells associated with at least one of the second network node or a third network node. Accordingly, the first network node may receive, from the second network node, an indication of the one or more intended TDD configurations. In some aspects, a first network node may receive, from a second network node, a request for one or more intended TDD configurations for one or more cells associated with at least one of the first network node or a third network node. Accordingly, the first network node may transmit, to the second network node, an indication of the one or more intended TDD configurations. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support delaying the application of reconfiguration messages. An integrated access and backhaul (IAB) node transmit or receive, along a first signaling path, a reconfiguration message indicating the first IAB node to postpone applying a reconfiguration message until a second signaling path becomes available. The first IAB node may send a reconfiguration complete message to a first IAB donor node along the first path and wait to perform a procedure with the first IAB donor node. When the second path becomes available, the first IAB node and the second IAB node may then perform the procedure. In some cases, delaying the reconfiguration may involve postponing the forwarding of messages received at the first IAB node.

Abstract: Present disclosure provides techniques for migrating integrated access and backhaul (IAB) nodes from the source centralized unit (CU) to a target IAB-donor-CU of a base station. Features of the present disclosure achieve such migration by configuring the IAB distributed unit (IAB-DU) to establish F1-connection (F1-C) with the target IAB-donor-CU via the source path before the user equipment (UE) context transfer occurs. To this end, the source IAB-donor-CU may initiate an F1-C establishment between IAB-node DU and target IAB-donor-CU. The source IAB-donor-CU may do so by acting or presenting as an IAB-node-DU proxy to the target IAB-donor-CU. At the same time, the source IAB-donor-CU may act or present as a target-IAB-donor-CU proxy to the IAB-node-DU. Thus, in some cases, the source IAB-donor-CU may present as both the IAB-node-DU proxy (to the target IAB-donor-CU) and as a target-IAB-donor-CU proxy (to the IAB-node-DU).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may configure an operation mode associated with releasing soft resources associated with an integrated access backhaul (IAB) network that supports implicit release of soft resources and explicit release of soft resources. The node may provide information that identifies the operation mode. Numerous other aspects are provided.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may determine a cell configuration of a distributed unit (DU) of the IAB node. The cell configuration may be associated with a second IAB donor. The DU may be one of a set of DUs of the IAB node. The IAB node may have a first signaling connection to a central unit (CU) of a first IAB donor. The IAB node may provide the cell configuration associated with the second TAB donor. Numerous other aspects are provided.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may send a request to a second BS to configure a backhaul routing path via the second BS to a third BS that has a signaling connection to the first BS. The apparatus may also communicate, with the second BS, a first backhaul adaptation protocol (BAP) configuration associated with the backhaul routing path. The apparatus may also transmit a second BAP configuration to the third BS in association with the communicated first BAP configuration.
