Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

Abstract: A method of wireless communication by a repeater includes collecting sensor information associated with an environment of the repeater. The method also includes receiving control information from a control node for a repeating operation. The method further includes repeating a wireless signal received from a first device towards a second device in accordance with the control information and the sensor information. A method of wireless communication by a control node includes collecting sensor information from a repeater. The sensor information is associated with an environment of the repeater. The method also includes generating control information for the repeater based on the sensor information, and transmitting the control information to the repeater.

Abstract: Methods, systems, and devices for wireless communications are described. A first node of an integrated access and backhaul (IAB) network may identify a second, neighboring non-parent node of the TAB network. The second node may be associated with a timing source which may provide more accurate timing information than the parent node of the first node. The first node may transmit a first random access message to the second node to initiate a random access procedure. The second node may transmit a second random access message to the first node, the second random access message including timing information based on the timing source. The first and second nodes may terminate the random access procedure based at least in part on receiving the second random access message.

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: 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: The present disclosure provides techniques for uplink resource management. For example, a method is provided including receiving a configuration granting a plurality of periodic uplink resources for use by the first wireless communication device to transmit data on an uplink. The method further includes determining for a first uplink resource of the plurality of periodic uplink resources, that grant of the first uplink resource for use by the first wireless communication device can be released. The method further includes based on the determining for the first uplink resource, transmitting to a second wireless communication device an indication that the grant of the first uplink resource for use by the first wireless communication device can be released.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node, a first message providing a first indication of integrated access and backhaul (IAB) capability. The first node may receive, from the second node and in response to the first message, a second message providing a second indication of IAB capability. The first node may establish an IAB capable connection with the second node based at least in part on the first message and the second message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may determine a forwarding direction for a set of resources based at least in part on time division duplexing (TDD) information associated with the set of resources. The forwarding direction may indicate a direction associated with forwarding signals carried in the set of resources. The repeater may receive a signal in the set of resources, the signal being provided by a first wireless communication device. The repeater may selectively forward the signal to a second wireless communication device based at least in part on the determined forwarding direction. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.
