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.

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: The present disclosure provides techniques for uplink resource management. For example, a method of wireless communication by a first communication device is provided including receiving, from a second communication device, a configuration allocating at least one uplink resource for use by the first communication device to transmit data on an uplink. The method further includes initiating preparing data for transmission on a first uplink resource of the at least one uplink resource prior to receiving an activation indication for the first uplink resource. The method further includes when the activation indication is received from the second communication device, transmitting uplink data on the first uplink resource to the second communication device. The method further includes when failing to receive the activation indication from the second communication device, refraining from transmitting uplink data on the first uplink resource.

Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a second wireless node, a cross-link interference (CLI) management configuration message including information identifying a time division duplexing configuration of a mobile terminal of a third wireless node; and communicate with one or more wireless nodes in accordance with the time division duplexing configuration of the mobile terminal based at least in part on transmitting the CLI management configuration message to the second wireless node. Numerous other aspects are provided.

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.

Abstract: Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.

Abstract: Aspects of the present disclosure provide techniques for handover in an Integrated Access and Backhaul (IAB) network or other type of network. One example method which may be performed by a source base station (BS) includes: determining to migrate a child node from a first logical IAB-distributed unit (DU) of an IAB-node to a second logical IAB-DU of the IAB-node, wherein the first logical IAB-DU is associated with the source BS, and wherein the second logical IAB-DU is associated with a target BS; sending, to the target BS, context information of the child node served by the first logical IAB-DU in response to the determination; and indicating, to the target BS, a traffic mapping configuration at the IAB-node associated with the context information and a backhaul connection of the IAB-node.

Abstract: Methods, systems, and devices for wireless communications are described. A mobile integrated access and backhaul (IAB) node may transmit, to an IAB supported network, an indication of IAB capability. The mobile IAB node may also indicate to the IAB supported network a mobility status associated with the mobile IAB node. The IAB supported network may conditionally determine authorization for the mobile IAB node based on the mobility status, a subscription status, or both. The IAB supported network may transmit, to the mobile IAB node, instruction to operate in an IAB mode and perform the IAB operation. The mobile IAB node may communicate with one or more devices based on the instruction.
