Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to a first integrated access and backhaul (IAB) donor central unit (CU), an indication of a first priority level associated with a first communication resource served by a distributed unit (DU) of the network node and a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level. The network node may receive, from the first IAB donor CU, a first resource configuration for the first communication resource based at least in part on the indication of the first priority level. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to an integrated access and backhaul (IAB) donor central unit (CU), information indicating a cell served by the network node and associated with another CU. The network node may receive, from the IAB donor CU, a distributed unit (DU) cell resource configuration for the cell. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (IAB) node. The IAB node receives one or more delay parameters from an IAB donor and determines an access PDB over an air link between the IAB node and a child node or a UE based in part on the one or more delay parameters received from the IAB donor.

Abstract: Aspects described herein relate to receiving, by a mobile termination (MT) function of an integrated access and backhaul (IAB) node, a first indication to migrate from a first IAB donor node associated with a first cell group and a first central unit (CU) to a second IAB donor node associated with a second cell group and a second CU, performing, by the IAB node and based at least in part on receiving the first indication, a first random access procedure to connect to the second cell group associated with the second IAB donor node, establishing, by the IAB node in addition to a first distributed unit (DU) function of the IAB node that serves a third cell group and based on performing the first random access procedure, a second DU function that serves a fourth cell group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive an indication of a plurality of sets of reference signal identifiers, wherein each set of reference signal identifiers of the plurality of sets of reference signal identifiers identifies reference signals of candidate neighbor nodes associated with the set, and wherein each candidate neighbor node associated with the set is in a same operating mode, and transmit a measurement report based at least in part on measuring one or more reference signals identified in the plurality of sets of reference signal identifiers. Numerous other aspects are provided.

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.

Abstract: Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless node may determine a configuration for interference measurement at the first wireless node, which may indicate a set of uplink resources for uplink reference signals and a beam sweeping configuration. Additionally, or alternatively, the configuration may indicate one or more resource sets configured for interference measurement. In some cases, the first wireless node may determine a set of transmission beams for the uplink reference signals based on the beam sweeping configuration, and the first wireless node may transmit the uplink reference signals via all of the transmission beams supported by the first wireless node.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on synchronization signal blocks (SSB) in a network (e.g., an Integrated Access and Backhaul (IAB) network. In some cases, a node determines resources used for periodic SSB transmissions by at least one parent node of the network, uses the determined resources to perform SSB-based interference measurements, and communicates with at least one of the parent node, a central unit (CU), or another node of the network based on the SSB-based interference measurements.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication by a mobile wireless node of a wireless backhaul communications network. In one aspect, the mobile wireless node determines a first set of communication resources for use by the mobile wireless node. The wireless node communicates with one or more wireless device, via one or multiple child links, using the first set of communication resources while the wireless backhaul communications network has a first topology and while the wireless backhaul communications network has a second topology.
