Abstract: An approach is described for a method for a base station in a fifth generation (5G) wireless c01mnunication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.

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: 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: 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.

Abstract: 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.

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.

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: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the LAB node for inter-IAB node discovery and measurements within an IAB network, the processing circuitry is to encode a first synchronization signal block (SSB-A) for transmission to an access UE using a first frequency resource from a synchronization raster set of frequency resources. A second SSB (SSB-B) is encoded for transmission to a second IAB node using a second frequency resource from an off-raster set of frequency resources. The off-raster set is non-overlapping with the synchronization raster set of frequency resources and the SSB-B being time-division multiplexed with the SSB-A. A measurement report from the second IAB node is decoded. The measurement report is based on the SSB-B and associated with a backhaul link between the IAB node and the second IAB node.
