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: 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: 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: Certain aspects of the present disclosure relate to methods and apparatus for providing quasi-colocation (QCL) signaling for reference signals (RS) and channels across scenarios involving multiple cells, such as coordinated multipoint (CoMP) scenarios in which multiple transmit receive points (TRPs) or integrated access and backhaul (IAB) nodes each have their own cell ID.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a scaling factor associated with determining a periodicity of backhaul physical random access channel (PRACH) resources. The wireless communication device may determine, based at least in part on the scaling factor, the periodicity of the backhaul PRACH resources. The periodicity of the backhaul PRACH resources may be extended as compared to a periodicity of access PRACH resources. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.

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.

Abstract: A first RAN may determine beamforming information for a UE served by the first RAN. Then, the first RAN may transmit, to a second RAN or a core network, paging information for the UE served by the first RAN, wherein the paging information comprises the beamforming information for the UE. A core network component, e.g., an AMF, may receive the paging information comprising the beamforming information for the UE and may send a paging request to a second RAN for the transmission of a paging message to the UE, wherein the paging request is based on the received paging information. The second RAN may receive, from the first RAN or from the core network, paging information for the UE comprising beamforming assistance information for the UE. The second RAN may then transmit a paging message to the UE based on the beamforming assistance information.

Abstract: Aspects of the present disclosure provide methods and apparatus for scheduling UEs in a wireless cell. The method generally includes determining one or more characteristics of communications on a first cell for a first type of user equipments (UEs) and a second type of UEs. A cell determines a first set of resources for the first type of UEs and a second set of resources for the second type of UEs based, at least in part, on the determined one or more characteristics and a resource bias parameter. The cell assigns the first set of resources for communications between the first cell and the first type of UEs and the second set of resources for communications between the first cell and the second type of UEs.
