Abstract: Systems, devices, and techniques for operating Integrated Access and Backhaul (IAB) nodes are described. A described technique includes transmitting, by an IAB-node, first synchronization signal blocks (SSBs) for access user equipment (UEs); and transmitting, by the IAB-node, second SSBs for inter-IAB-node discovery and measurement. The technique can include measuring, by the IAB-node, one or more third SSBs for inter-IAB-node discovery and measurement, and attaching to another IAB-node that is discovered based on the measuring.

Abstract: Embodiments of this disclosure include apparatuses and methods for data channel mapping type and demodulation reference signal (DM-RS) configuration to enable a physical layer (L1) crosslink interference (CLI) measurement and reporting. Some embodiments are direct to a method of operating a base station (BS), where the method can include generating, by the BS, a demodulation reference signal (DM-RS), determining, by the BS, a position of the DM-RS in a first transmission slot, transmitting, by the BS, the DM-RS to a UE based on the determined position in the first transmission slot, processing, by the BS, a crosslink interference (CLI) measurement fed back based on the DM-RS, wherein the CLI measurement fed back is in a channel state information (CSI) report, and performing, by the BS, a CLI mitigation based on the CLI measurement.

Abstract: 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.

Abstract: 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.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for dynamic indication of soft resource availability. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) node. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive, from a second IAB node, a slot format indicator (SFI). The SFI can include a slot format entry including a soft symbol indicating availability of a soft resource. The processor circuitry can be configured to use the slot format entry to communicate with a third IAB node, different from the second IAB node, using the soft resource as indicated by the soft symbol.

Abstract: This disclosure relates to embodiments broadcasting timing misalignment (ΤΔ or T_ delta or Tdelta) information in a fifth generation (5G) new radio (NR) integrated access and backhaul (IAB) network. Tdelta information associated with an IAB node is determined based on a downlink (DL) transmit (TX) timing associated with the IAB node and an uplink (UL) receive (RX) timing associated with the IAB node. A determination is made whether the Tdelta information is to common to at least one child node associated with the IAB node and at least one child user equipment (UE) associated with the IAB node. 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 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.
