Abstract: Aspects of the present disclosure provide techniques for packet delay budget (PDB) coordination between two integrated access and backhaul (TAB) nodes for a radio link control (RLC) channel in an TAB network. An TAB node may dynamically adjust its configured one-hop RLC channel PDB based on channel conditions or buffer loading associated with the TAB node. The TAB node may then indicate bonus PDB at a next-hop node or request additional PDB from the next-hop node.

Abstract: An integrated access and backhaul (IAB) apparatus transmits a set of values to a child IAB node corresponding to a transition type for the child IAB node, determines that the child IAB node will perform a transition at a transition time with a symbol adjacent to the transmission time having a flexible resource type, and provides a number of guard symbols at the transition time based on determining that the symbol has the flexible resource type.

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: Methods, systems, and devices for wireless communications are described. A base station (e.g., a central unit (CU) function of the base station) may select, from a set of distributed units (DUs) associated with the CU, a DU of an integrated access and backhaul (IAB) node to control sidelink communications for a user equipment (UE). The base station may determine a configuration of sidelink parameters for the sidelink communications with the UE, the sidelink parameters comprising an identification of the selected DU. The base station may transmit, to the TAB node performing sidelink communications with the UE, an indication of the configuration of sidelink parameters for the sidelink communications.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node in a wireless multi-hop network may identify a power supply category of the node based at least in part on a manner in which the node is supplied with power, wherein the power supply category indicates whether the node is supplied with power from an alternating current power supply or a battery power supply. The node may transmit a power status report to another node in the wireless multi-hop network, wherein the power status report indicates the power supply category of the node. Numerous other aspects are provided.

Abstract: An apparatus receives an indication of a Physical Cell Identifier (PCI) change for a serving integrated access and backhaul (IAB) node and uses the new PCI value for receiving communication from the serving IAB node based on the indication of the PCI change. The apparatus may comprise a user equipment (UE) or a mobile termination (MT) of a child IAB node that is served by the IAB node.

Abstract: In some aspects, a network node may determine a connection identifier associated with transmitting data to a decoder node via multiple paths, wherein the connection identifier is associated with a single radio bearer of a user equipment (UE); encode a first portion of data into first packets and second packets; transmit the first packets and the connection identifier to the decoder node via a first path; transmit the second packets and the connection identifier to the decoder node via a second path; receive a response from the decoder node, wherein the response includes the connection identifier; and transmit, to the decoder node and based at least in part on the response, one of: third packets, encoded from the first portion of data, and the connection identifier, or one or more sets of packets, encoded from a second portion of data, and the connection identifier.

Abstract: A central entity determines a physical cell identifier (PCI) change of an integrated access and backhaul (IAB) node from a first PCI to a second PCI and sends the second PCI to the IAB node. In response to receiving the second PCI from the central entity, the IAB node changes from using the first PCI to using the second PCI for the IAB node.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications in a network. A method includes receiving, from a first user equipment, a first uplink trigger message in a receive direction while in a first energy mode, wherein while in the first energy mode, the network entity is configured to: deactivate any synchronization signal blocks (SSBs) in the receive direction; monitor for uplink trigger messages during one or more configured uplink trigger occasions; and transitioning from the first energy mode to a second energy mode based at least in part on the first uplink trigger message, wherein while in the second energy mode, the network entity is configured to: activate one or more SSBs in the receive direction; and monitor for uplink trigger messages during the one or more configured uplink trigger occasions.
