Abstract: An apparatus for an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for resource availability indication in an IAB network, configuration signaling received from a CU function of an IAB donor node is decoded at a DU function of the IAB node. The configuration signaling configures a frequency-domain hard, soft, and not available (H/S/NA) resource application for a plurality of resource types. DCI received from a P-DU function of a parent IAB node is decoded at an MT function of the IAB node. The DCI includes an availability indicator for at least one soft resource region associated with the frequency-domain H/S/NA resource application. A downlink transmission by the DU function of the IAB node to a C-MIT function of a child IAB node is configured using the at least one soft resource region based on the availability indicator.

Radio resource control (RRC) signaling, a Medium Access Control (MAC) control element (CE), or downlink control information (DCI) contains the beam information.

A message having the Tdelta information is generated in response to the determination that the Tdelta information is common to at least one child node associated with the IAB node and at least one child UE associated with the IAB node. The message is broadcast to the child nodes associated with the IAB node and the child UEs associated with the IAB node.

Abstract: 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).

Abstract: Some embodiments of this disclosure include apparatuses and methods for determining synchronization signal block (SSB) periodicity for cell reselection. In some embodiments, user equipment (UE) may establish a first connection with a first integrated access and backhaul (IAB) node using a first SSB periodicity. The UE may perform a cell reselection process and determine whether a number of candidate IAB nodes include a candidate IAB node with a previously stored candidate SSB periodicity corresponding to the candidate IAB node. If the UE identifies a candidate SSB periodicity, the UE may establish a second connection with the candidate IAB node using the candidate SSB periodicity. If the UE does not identify a previously stored candidate SSB periodicity, the UE may establish a second connection with a second IAB node using a second SSB periodicity that is less than the first SSB periodicity.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Some embodiments of this disclosure include apparatuses and methods for providing semi-static integrated access backhaul (IAB) resource configurations in an IAB network. For instance, a central unit (CU) of an IAB donor can provide, to a distributed unit (DU) of an IAB node, F1 application protocol (F1AP) signaling data indicative of a semi-static IAB resource configuration regarding at least one of downlink resources, uplink resources, or flexible resources. The semi-static IAB resource configuration indicates whether the at least one of downlink resources, uplink resources, or flexible resources are hard resources, soft resources, or not available resources. The CU can further provide, to a mobile termination (MT) of the IAB node, radio resource control (RRC) signaling data indicative of the semi-static IAB resource configuration.
