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.

Abstract: Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.

Abstract: Methods, systems, and devices for wireless communication are described for a beam-aware handover procedure for multi-beam access systems. A source base station may determine that a handover request is to be sent to a target base station in preparation for handover of a user equipment (UE) from the source base station to the target base station, and transmit the handover request to the target base station with an indication of whether the handover is to be delayed. Alternatively or in addition to, either the target base station or the source base station may generate and transmit a time expiration indicator. The indication of whether the handover is to be delayed or the time expiration indicator may allow either the target base station or the UE to determine whether access parameters for the UE are valid.

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: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. A central unit (CU) transmits over a backhaul link a message to a distributed unit (DU) including a resource configuration for a DU cell and a child cell corresponding to a child node served by the DU cell. The DU determines that the message misidentifies the child cell using an ID of a different cell. In response to that determination, the DU communicates with the child node based on the resource configuration specific to the misidentified child cell. Using this coordinated technique enables the CU to provide the DU with a child-node specific resource configuration to enable the DU to use this configuration for communicating with the child node. This maximizes efficiency in multi-node communications between one or more child nodes and cells while adding minimal, if any, signaling overhead.

Abstract: Various types of communication may switch from an unlicensed spectrum to a licensed spectrum. MiCr communication may be synchronized based on transmission time intervals (TTIs), which may improve the duration required to switch between bands. A MiCr system may transmit a signal to temporarily suspend other traffic in a licensed band so that MiCr communication may occur. For example, an apparatus may be configured to determine synchronization between a first radio access technology (RAT) and a second RAT based on transmission time intervals associated with the first RAT and transmission time intervals associated with the second RAT, switch from the first RAT to the second RAT after the determined synchronization between the first RAT the second RAT; and transmit, during a TTI associated with the second RAT, a first packet using the second RAT based on the switch from the first RAT to the second RAT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive an indication of a plurality of sets of reference signal identifiers, wherein each set of reference signal identifiers of the plurality of sets of reference signal identifiers identifies reference signals of candidate neighbor nodes associated with the set, and wherein each candidate neighbor node associated with the set is in a same operating mode, and transmit a measurement report based at least in part on measuring one or more reference signals identified in the plurality of sets of reference signal identifiers. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for hop-count indication in an integrated access and backhaul (IAB) network. An IAB-node may adopt and indicate multiple values for hop-count. The hop-count may be conveyed by a number of different reference signals and channels. A resource pattern and/or a slot pattern may also be associated with the hop-count to simply signaling. By associating the patterns with the hop-count, an IAB-node may be able to infer the resource pattern used by another IAB-node.

Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for types of traffic separately. A centralized scheduler in a centralized system or a set of access nodes (ANs) in a distributed system may allocate a portion of a set of resources for a first traffic type (e.g., control or data traffic). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given traffic type. The allocated resources may be repurposed for use by a different traffic type (e.g., data traffic resources may be repurposed an used for control traffic resources) in order to account for varying traffic conditions (e.g., unscheduled control traffic).
