Embodiments of the present disclosure describe methods and apparatuses for measurements and reports in integrated access and backhaul networks.

Inter-integrated access and backhaul node cross-link interference measurement and reporting

Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems for allocating resources include allocating a first cell-specific pattern of downlink-flexible-uplink (DL-F-UL) availability for one or more slots, allocating a second cell-specific pattern of DL-F-UL availability for the one or more slots. The IAB DU can signal one or more of the first and second cell-specific patterns to an other IAB DU. At least one of the first cell-specific pattern and the second cell-specific pattern defines a slot format different from a DL-F-UL format. Slot format configuration (e.g., semi-static or dynamic SFI) are provided to support space division multiplexing/spatial multiplexing (SDM).

Slot formats for semi-static download-uplink configuration and dynamic slot format indication in integrated access and backhaul networks

Apparatuses for non real-time (Non-RT) radio access network intelligence controller (RIC) and Near-RT RIC services for machine learning (ML) model management in an open radio access network (O-RAN) are disclosed. The services include ML model monitoring, getting and putting ML models from and to an AI-ML producer and an AI-ML consumer, and terminating the use of an ML mode. The ML model monitoring includes the AI-ML consumer sending monitoring data to the AI-ML producer and the AI-ML producer processing the monitoring data and taking actions based on the monitoring data. The services may be performed over the AI interface using HTTP.

ML model management in O-RAN

Systems, methods, and circuitries are provided for communicating DU resource configuration information of a child IAB node to a parent IAB node. An example method includes identifying distributed unit (DU) resource configuration information for an IAB node device functioning as an IAB node in the IAB network, wherein the IAB node is associated with a parent IAB node, and transmitting the DU resource configuration information to the parent IAB node.

Child distributed unit resource configuration information signaling in 5G-NR integrated access backhaul network

A data-centric network and non-Real-Time (RT) RAN Intelligence Controller (RIC) architecture are described. The data-centric network architecture provides data plane functions (DPFs) that serve as a shared database for control functions, user functions and management functions for data plane resources in a network. The DPFs interact with control plane functions, user plane functions, management plane functions, compute plane functions, network exposure functions, and application functions of the NR network via a service interface. The non-RT RIC provides functions via rApps, manages the rApps, performs conflict mitigation and security functions, monitors machine learning (ML) performance, provides a ML model catalog that contains ML model information, provides interface terminations and stores ML data and Near-RT RIC related information in a database. An ML training host trains and evaluates ML models in the catalog, obtains training and testing data from the database, and retrains and updates the ML models.

Data-centric service-based network architecture

An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for resource allocation within an IAB network, the processing circuitry is to decode radio resource control (RRC) signaling from a central unit (CU) function of an IAB donor node. The RRC signaling configures first time-domain resources for a parent backhaul link between a mobile termination (M) function of the IAB node and a distributed unit (DU) function of a parent IAB node, and second time-domain resources for a child backhaul link between a DU function of the IAB node and a MT function of a child IAB node. Uplink data is encoded for transmission to the parent IAB node based on the first time-domain resources. Downlink data is encoded for transmission to the child IAB node based on the second time-domain resources.

Resource allocation in IAB networks

The present disclosure is directed to systems and methods for conveying remote interference management information via a reference signal. For example, an interference management method may include receiving, at a first device, an interference signal from a second device. At the first device, a reference signal is generated, including mitigation information for remote interference management. The first device may transmit the reference signal to the second device. The method may further include receiving, at the first device, a mitigation response signal indicative of a level of mitigation undertaken by the second device based on the mitigation information that the first device transmitted.

Method for conveying remote interference management information via reference signal

Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (Beam Failure Recovery) and RLF. A first mechanism that can be employed in various embodiments can perform one or more RLF-related actions (e.g., stopping a T310 timer, resetting a N310 counter) upon BFR success. A second mechanism that can be employed in various embodiments can comprise revising one or more RLF parameters (e.g., N310, N311, T310, Out-of-sync threshold, in-sync threshold, etc.) based on the presence of a strong BFR mechanism.

An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for time-domain resource management within an IAB network, the processing circuitry is to detect that a time-domain resource assigned to a child communication link of the IAB node is available. An uplink message is encoded for transmission by a mobile terminal (MT) function of the IAB node to a parent IAB node. The uplink message indicates availability of the time-domain resource for a parent backhaul link between the IAB node and the parent IAB node. A downlink message from the parent IAB node is decoded. The downlink message is received via the parent backhaul link and using the time-domain resource.

IAB MT signaling of released resources

Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems include configuring one or more resources to allocate time-domain or frequency domain availability/utilization. Configurations of resources can be aligned between one or more nodes such that resource availability of a first node can be coupled to resources of a second node. Allocated resources can include uplink, downlink, and flexible resources. Allocated resources can be indicated as not available, hard, or soft resource types. A configuration pattern can indicate a sequence of time-domain resource or frequency domain resource availability of a DU in the IAB network.

Resource configuration schemes for an integrated access and backhaul distributed unit

Disclosed herein are system, method, and computer program product embodiments verifying legitimate victim-aggressor pairs in remote interference management operation. In an embodiment, a first even report is generated by a victim base station based detection of an atmospheric duct and it transmits a victim reference signal with the first event report. The first event report includes an ID of the victim base station. An aggressor base station is triggered to begin monitoring for transmission of the victim reference signal. The aggressor base station sends a second event report if it detects the victim reference signal. The central entity tries to verify that the victim and aggressor are legitimate. If the verification passes, then the central entity sends a message to the aggressor to start of remote interference mitigation. If verification fails, the remote interference mitigation is not triggered and the victim reference signal is ignored.

Apparatus and method for protecting against victim masquerade attack in remote interference management

Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for random access channel (RACH) resource coordination. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) network. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive random access channel (RACH) resource configuration for communicating with a parent node and a child node. The processor circuitry can be configured to determine, based on the RACH resource configuration, a first RACH resource for communicating, in a half-duplex mode, with the parent node. The processor circuitry can be further configured to determine, based on the RACH resource configuration, a second RACH resource for communicating, in the half-duplex mode, with the child node, where the second RACH resource is orthogonal to the first RACH resource.

RACH resource coordination mechanisms for adjacent hops in IAB

Some embodiments of this disclosure include apparatuses and methods for measuring and/or reporting UE-to-UE crosslink interference (CLI). In some embodiments, a communication network may use transmission reception points (TRPs) to facilitate communications for user equipment (UE). A first TRP may command a first UE to transmit a crosslink interference reference signal (CLI-RS) according to a particular time behavior. A second TRP may command a second UE to measure UE-to-UE CLI using the CLI-RS and the time behavior. The second UE may then report the measured CLI indicating a level of interference caused by the first UE.

UE to UE crosslink interference measurement and reporting

Systems, apparatuses, methods, and computer-readable media are provided for Remote Interference Management (RIM) in wireless networks, including RIM reference signals (RIM-RS) transmitted to assist victim Radio Access Network (RAN) nodes to identify aggressor RAN nodes due to, for example, atmospheric ducting. The RIM-RS is also bandwidth-flexible in order to enable detection of the RIM-RS by aggressor RAN nodes with different bandwidth configurations. Other embodiments may be described and/or claimed.
