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: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions. For example, wireless devices communicating over a backhaul network may have a higher link budget than wireless devices communicating over an access network. As such, RACH preambles transmitted by the wireless devices communicating over the backhaul network may be shorter than RACH preambles transmitted by the wireless devices communicating over the access network.

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: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described in which RF-domain wireless routers may repeat, extend, or redirect beamformed wireless signals received from one or more transmitters to one or more receivers. The router may receive transmissions at a mmW frequency using a first array of antenna elements, and provide the transmissions to a beamforming network, such as a Butler matrix, that outputs one or more a signals to a switching network. The switching network may perform switching to provide the one or more signals to desired inputs of an output beamforming network that outputs beamformed transmission beams via a second array of antenna elements.

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: Aspects relate to a physical cell identifier (PCI) change within a wireless network based on a primary synchronization signal (PSS) waveform. A scheduling entity, such as an integrated-access-backhaul (IAB) node within a radio access network (RAN), may communicate with a set of one or more scheduled entities, such as other IAB nodes and/or user equipment (UEs), utilizing a first PCI. The scheduling entity may then change from the first PCI to a second PCI, where the second PCI corresponds to a different PSS waveform than the first PCI. In some examples, the scheduling entity may change the PCI as a result of a PCI collision and/or PSS collision with a neighboring scheduling entity.

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: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) system may perform contention window updates on an IAB node for different components of the IAB node. In some implementations, the IAB node may perform separate contention window updates in separate reference durations for the different components. Additionally or alternatively, the IAB node may perform a joint contention window update for the different components, where a single reference duration for updating contentions windows for the components may be defined for the IAB node that includes transmissions for both components. Additionally or alternatively, the IAB node may perform separate contention window updates for the different components based on the single reference duration that includes transmissions for both components, where feedback may be used separately to update corresponding contention windows.

Abstract: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may include a first component for communications with a parent node and a second component for communications with a child node. The IAB node may perform a first channel access procedure for a first fixed frame period associated with the first component. The IAB node may perform a second channel access procedure for a second fixed frame period associated with the second component, the second fixed frame period staggered in time with respect to the first fixed frame period in accordance with an offset. The IAB node may communicate with one or more wireless devices during a first channel occupancy time associated with the first fixed frame period, during a second channel occupancy time associated with the second fixed frame period, or a combination thereof based on performing the channel access procedures.
