Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a first integrated access and backhaul (IAB) donor central unit (CU), information indicating a first resource configuration used by an IAB node that has a first connection with a first parent IAB node that is a child of the first IAB donor CU. The first network node may transmit, to a second parent IAB node that is a child of the first network node, the information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Idle discontinuous reception (I-DRX) configurations may be managed on a per beam or a per subset of beams basis. The network may indicate, via system information, the I-DRX configuration for a given beam or subset of beams. A user equipment (UE) in an idle mode may receive paging occasions via the given beam in accordance with the indicated I-DRX configuration for that beam. In some examples, system information may indicate a list of beams and corresponding I-DRX configurations for each beam in the list of beams. In some examples, system information may indicate the I-DRX configuration for the beam on which the system information is transmitted. If a UE changes beams, the UE may receive system information via the new beam that indicates an I-DRX configuration for the new beam before applying the I-DRX configuration to the new beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB)-donor central unit (CU) may trigger connectivity between a distributed unit (DU) of a first network node and the IAB-donor CU, wherein the first network node comprises an IAB-node. The IAB may instantiate connectivity between a mobile terminal (MT) of the first network node and the IAB-donor CU after instantiation of the connectivity between the DU of the first network node and the IAB-donor CU. The IAB may transmit a communication to a second network node via the first network node. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity may determine a set of schedulable resources for a plurality of links associated with a plurality of nodes of a multi-link network; and may provide scheduling information to the plurality of nodes to schedule communication on the plurality of links based at least in part on determining the set of schedulable resources. In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink transmission to a base station is to occur in accordance with an uplink timing advance value representing an amount of time that the uplink transmission takes from transmission at the UE to reception at the base station. The UE may perform an autonomous open-loop adjustment to the uplink timing advance value. The UE may transmit the uplink transmission to the base station in accordance with the adjusted uplink timing advance value. The base station may transmit an indication of a set of uplink timing advance values for a UE to use for uplink transmissions, each of the set of uplink timing advance values representing an amount of time that an uplink transmission is expected to take from transmission at the UE to reception at the base station.

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.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UL LBT status reporting. A scheduled node (e.g., a UE) may sense a status of each LBT channel in a set of one or more LBT channels. The set of one or more LBT channels may include at least one of one or more first LBT channels associated with a scheduling grant or one or more second LBT channels unassociated with the scheduling grant. The scheduled node may transmit, to a scheduling node (e.g., a base station), a LBT status report indicative of the status of each LBT channel in the set of one or more LBT channels. The scheduling node may schedule, via a second scheduling grant, a second set of one or more LBT channels based on the status of each LBT channel indicated in the LBT status report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.
