Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may receive, from a wireless node, a status report of an unlicensed band associated with an unlicensed channel access of the wireless node, wherein the status report indicates listen-before-talk (LBT) failures during the unlicensed channel access of the wireless node. The control node may transmit, to the wireless node, an updated configuration for unlicensed channel access based at least in part on the status report of the unlicensed band. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node. The apparatus may receive communication from one or more of a parent IAB node or a child IAB node using a first frequency carrier of a paired spectrum comprising the first frequency carrier and a second frequency carrier. The apparatus may transmit communication to the one or more of the parent IAB node or the child IAB node using the second frequency carrier in the paired spectrum. At least one of the first frequency carrier or the second frequency carrier in the paired spectrum carries both uplink and downlink communication.

Abstract: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.

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.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus of a first network node are provided. The first network node may send quality of service (QoS) information and a request to a second network node to configure, based on the QoS information, a backhaul routing path for traffic between the first network node and a third network node via the second network node, the third network node having a signaling connection with the first network node. The first network node may communicate, with the second network node in response to the request, QoS mapping information. The first network node may configure an Internet protocol (IP) header of an IP packet based on the communicated QoS mapping information. The first network node may send the IP packet with the configured header to the second network node for routing through the backhaul routing path.

Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. A central unit (CU) transmits over a backhaul link a message to a distributed unit (DU) including a resource configuration for a DU cell and a child cell corresponding to a child node served by the DU cell. The DU determines that the message misidentifies the child cell using an ID of a different cell. In response to that determination, the DU communicates with the child node based on the resource configuration specific to the misidentified child cell. Using this coordinated technique enables the CU to provide the DU with a child-node specific resource configuration to enable the DU to use this configuration for communicating with the child node. This maximizes efficiency in multi-node communications between one or more child nodes and cells while adding minimal, if any, signaling overhead.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may generate an intended time division duplexing (TDD) downlink-uplink (DL-UL) configuration, wherein the network node is associated with a first central unit (CU) and a second CU, and wherein the intended TDD DL-UL configuration is for a cell that is served by the network node and associated with the second CU. The network node may transmit the intended TDD DL-UL configuration for the cell to the first CU. Numerous other aspects are described.

Abstract: A first control node may communicate with a user equipment (UE) using an integrated access and backhaul (IAB) network, and a second control node may manage a configuration of the IAB network. The second control node may not have the information needed to configure the IAB network, such as quality of service (QoS) information associated with a data radio bearer (DRB) used for communications between the first control node and the UE, and thus may not be able to configure a user plane interface tunnel and/or a radio link control (RLC) channel to assist with satisfying the QoS level. Some techniques and apparatuses described herein enable the second control node to receive QoS information associated with setting up a user plane interface tunnel between the first control node and an IAB node that serves a UE for which the user plane interface tunnel is being set up.

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.
