Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may receive a resource management indication from a network node to identify a resource utilization with communications of the network node; determine, based at least in part on the resource management indication, a collision management configuration for the network node; and transmit information associated with the collision management configuration based at least in part on the determination of the collision management configuration. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may determine a mobility state. The network node may determine a communication configuration, selected from a plurality of communication configurations associated with a plurality of mobility states, based at least in part on the mobility state. The network node may perform a communication procedure using the selected communication configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques of allocating time resources (or slots) based on a flexible pattern that allows allocation of a set of non-continuous time slots resources in an integrated access and backhaul (IAB) system. In one example, the aggregation pattern may be indicated via a single downlink control information (DCI) message that carries explicit information regarding non-continuous time slot allocation. Features of the present disclosure may also include techniques to allow for early termination of transmission between the first node and the second node when the receiver (e.g., second node) successfully receives the data channel before the end of aggregated transmission. In such situation, the first node and the second node may cease transmission after reception of an acknowledgement (ACK) message that may allow the second node to utilize the subsequent time slots for communication with its own children on the next hop (e.g., third node).

Abstract: In some aspects, a wireless node in a wireless multi-hop network may receive, from a central unit in the wireless multi-hop network, a configuration indicating that a first wireless interface between the wireless node and a first parent node of the wireless node is to be used for a first traffic type, and that a second wireless interface between the wireless node and a second parent node of the wireless node is to be used for a second traffic type; configure a first connection with the first parent node via the first wireless interface and a second connection with the second parent node via the second wireless interface based at least in part on the configuration; and transmit or receive a communication using the first connection or the second connection based at least in part on a traffic type of the communication.

Abstract: A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in a SDM operation between the child node and the parent node.

Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node transmits a report to a CU, where the report includes at least one multiplexing capability or condition of the first node. The first node receives a semi-static resource allocation from the CU based on the at least one multiplexing capability, and the first node communicates with a second node based on the semi-static resource allocation. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.
