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: In a channel occupancy time (COT), a scheduling entity can transmit a first downlink (DL) transmission burst to a scheduled entity, and receive an uplink (UL) transmission burst from the scheduled entity. The scheduling entity can determine whether the scheduled entity performed a type 1 or type 2 channel access procedure for the UL transmission burst. A scheduled entity can use a first type of channel access procedure to initiate a first COT on a communication channel and request a network access node to perform a second type of channel access procedure in a next DL transmission burst. A network access node can receive a message from a scheduled entity, wherein the message comprises a control indication requesting the network access node to perform a first type of channel access procedure in a next DL transmission burst.

Abstract: Aspects relate to technologies and techniques for migrating a radio access network (RAN) node associated with a first donor node in a communications network. The first donor node may receive, via a first communications interface, such as an F1-C or resource control (RRC) interface, cell configuration data associated with one or more cells of the RAN node activated by the first donor node. The first donor node may process the cell configuration data and transit the cell configuration data, using a second communications interface, such as an Xn or X2 interface, to a second donor node for use in migrating the RAN node from the first donor node to the second donor node.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding conflicts of resources assigned to one or more signals with resources assigned to Random Access Channel (RACH) in an Integrated Access and Backhaul (TAB) network. Configurations for first and second sets of signals are obtained for a first and second base station (BS) respectively. Based on the obtained configurations, a RACH configuration is determined for the first BS for performing a RACH procedure with the second BS over a wireless backhaul link, wherein one or more Physical RACH (PRACH) occasions according to the determined RACH configuration do not conflict with resources used for at least one of the first or the second set of signals. The determined RACH configuration is communicated to the second BS, wherein the second BS transmits a RACH signal to the first BS based on the determined RACH configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive configuration information associated with configuring involvement of the repeater in an access procedure; receive a signal associated with the access procedure from a first wireless communication device; and forward the signal associated with the access procedure to a second wireless communication device based at least in part on the configuration information and other information, associated with the access procedure, received by the repeater. 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: 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; and 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). One example method generally includes determining, based on a priority level associated with each of a first wireless node, a second wireless node, or both, at least one configuration for communicating one or more synchronization signal blocks (SSBs) between the first wireless node and the second wireless node, each of the first wireless node and the second wireless node being configured to serve one or more child nodes, wherein the at least one configuration comprises information enabling the first wireless node or the second wireless node to manage interference to communications. In some aspects, the method may also include transmitting the at least one configuration to at least one of the first wireless node or the second wireless node.

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.
