Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.

Abstract: An integrated access and backhaul (IAB) node receives, from a parent IAB node, a time difference parameter for over-the-air (OTA) synchronization in an IAB network. The IAB node adjusts transmission or reception of the IAB node based on the time difference parameter for one of multiple types of IAB node alignment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for inter-donor topology discovery in an Integrated Access and Backhaul (IAB) network during migration of an IAB-node. A method that may be performed by a first IAB-donor includes establishing a first signaling connection with an IAB-node, receiving an indication that the IAB-node has a second signaling connection with a second IAB-donor, and in response to receiving the indication: transferring, to the second IAB-donor, information related to the IAB-node, re-establishing traffic between the first IAB-donor and the IAB-node via a topology of the second IAB-donor, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive at least part of a resource pattern of a child IAB node associated with the IAB node. The resource pattern may indicate one or more configurations of one or more resources of the child IAB node. The IAB node may communicate with the child IAB node based on the at least part of the resource pattern. Numerous other aspects are provided.

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 network node may transmit, to first central unit (CU) that corresponds to an integrated access and backhaul (IAB) donor, an indication of a first resource configuration for communications corresponding to a cell served by the network node and associated with a second CU that corresponds to a base station. The network node may receive, from the first CU, a second resource configuration comprising a distributed unit (DU) cell resource configuration for the cell. 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 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: Aspects of the present disclosure may provide an apparatus, which may include a first node that may receive an indication of a one-hop radio link control (RLC) channel packet delay budget (PDB) for an RLC channel between the first node and a second node. The PDB is across a full protocol stack or a partial protocol stack. The first node may then schedule communications with the second node based on the one-hop RLC channel PDB. In some cases, an IAB node may report a capability of its stack processing time to an IAB donor node and/or a parent IAB node (directly or indirectly).

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (TAB) node. The TAB node receives a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission. The TAB node performs a discard decision for the packet based on the first delay parameter associated or schedules the packet for transmission to a second TAB node or a user equipment (UE) using a second delay parameter associated with the packet. A central unit (CU) of an TAB network may indicate, to an TAB node, the second delay parameter for scheduling a packet and the first delay parameter for determining whether to discard the packet.
