Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a first integrated access and backhaul (IAB) donor central unit (CU), information indicating a first resource configuration used by an IAB node that has a first connection with a first parent IAB node that is a child of the first IAB donor CU. The first network node may transmit, to a second parent IAB node that is a child of the first network node, the information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node in an integrated access and backhaul (IAB) network may transmit, to an IAB node having a mobile termination function (IAB-MT) and a distributed unit (IAB-DU), signaling indicating a set of restricted IAB-DU beams and associating the set of restricted IAB-DU beams with one or more IAB-MT beams, the set of restricted IAB-DU beams determined based on measurements related to interference caused by the IAB-DU and the IAB-MT performing a simultaneous operation in one or more simultaneous multiplexing modes. Additionally or alternatively, the parent node may perform scheduling for the IAB-MT based on signaling received from the IAB node that indicates beam-specific parameters related to a multiplexing capability for a beam pair that includes an IAB-MT beam and an IAB-DU beam associated with the IAB-MT beam. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive, from a distributed unit (DU), a first DU configuration. The CU may transmit to the DU, a second DU configuration to change a DU configuration from the first DU configuration to the second DU configuration, the first DU configuration being different from the second DU configuration. The DU may override the first DU configuration to communicate in accordance with the second DU configuration. Numerous other aspects are provided.

Abstract: Aspects generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive a configuration that indicates multiple resource patterns for one or more slots, wherein each resource pattern corresponds to a different set of one or more resource block (RB) sets within the one or more slots, and wherein each resource pattern includes at least one of: a resource availability pattern that indicates at least one of hard resources, soft resources, or not available resources for one or more RB sets corresponding to that resource pattern, or a resource directionality pattern that indicates at least one of uplink resources, downlink resources, or flexible resources for the one or more RB sets corresponding to that resource pattern. The IAB node may apply a resource pattern, of the multiple resource patterns, based at least in part on the configuration. Numerous other aspects are described.

Abstract: A first base station may establish a first connection with an IAB node and transmit, to a second base station, a request for the second base station to establish a second connection with the IAB node. The first base station may indicate to the second base station, based on the second connection being established with the IAB node, that at least one of a first base station or the second base station is to serve as an IAB donor for the IAB node. The second base station may accept or reject the indication received from the first base station that the at least one of the first base station or the second base station is to serve as the IAB donor for the IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source integrated access and backhaul (IAB) donor central unit (CU) may transmit, to an IAB node having a first signaling connection with the source IAB donor CU, a trigger to establish a second signaling connection between the IAB node and a target IAB donor CU. The source integrated access may transmit, to the IAB node, transport network layer address information associated with the target IAB donor CU to enable the IAB node to establish the second signaling connection with the target IAB donor CU. The IAB node may transmit, to the target IAB donor CU, a request to establish the second signaling connection with the target IAB donor CU based at least in part on the trigger. Numerous other aspects are provided.

Abstract: In an IAB network, a third network node sends QoS mapping information to a first network node to configure an IP header for a packet based on a traffic type and to transmit the packet. The third network node sends a mapping configuration to a second network node to map information in the IP header for the packet received in a first routing path from the first network node to a second routing path. The first network node receives the QoS mapping information and generates a packet associated with the traffic type and including an IP header, which is configured based on the received QoS mapping information. The first network node transmits the packet for routing to the second network node.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus of a network node are provided. The network node may receive, from a second network node, a routing configuration that maps a packet to a routing identifier (ID) based on a first header in the packet. The network node may receive a packet from a pre-hop node, the packet including the first header with a first address and a second header with a second address. The network node may determine that the second address matches an address of the first network node and that the first address mismatches an Internet protocol (IP) address of the first network node. The network node may replace, based on the received routing configuration and based on the address match and address mismatch determination, the second header with a third header, the third header including the routing ID.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a node or a base station. In one aspect, the apparatus may receive, via a first set of resources, communication including at least one data packet, the first set of resources allocated for a reception entity of the node. The apparatus may also decode, at the reception entity, the at least one data packet during a decoding period, the decoding period including a decoding start time and a decoding completion time. Additionally, the apparatus may transmit, via a second set of resources, the communication including the at least one data packet to a next hop node, the second set of resources allocated for a forwarding entity of the node, at least one first resource overlapping with at least one second resource.
