    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.

    Abstract: Systems and methods of providing policy and charging control in an information-centric network are described. An interest packet is transmitted from a content consumer to a holder through a gNB, ICN-PoA and ICN-GW. The interest packet has a prefix identifying content to be retrieved and a type field indicating an interest packet. The ICN-PoA modifies the interest packet to include a type of service (TS) field having the identity of the consumer and then transmitted to the ICN-GW when the content is neither created nor cached inside the 5G network. A data packet that includes the prefix, a type field indicating a data packet and the TS field is returned from the ICN-GW. The data packet is modified by the ICN-PoA to remove the TS field and transmitted to the consumer. The interest and data packets are logged and reported to an ICN-CF for generation of charging records.

    Abstract: Embodiments of the present disclosure describe methods and apparatuses for measurements and reports in integrated access and backhaul networks. An integrated access and backhaul (IAB) node is configured to: receive radio resource control (RRC) signaling from a IAB donor node, the RRC signaling to include configuration information with respect to reference signals of the IAB donor node or one or more neighboring IAB nodes; perform one or more measurements based on the reference signals of the donor node or the one or more neighboring IAB nodes; and transmit measurement report to the IAB donor node, the measurement report to include an indication of results of the one or more measurements.

    Abstract: Some embodiments of this disclosure include apparatuses and methods for supporting integrated access and backhaul (IAB) networks. IAB nodes may be configured to broadcast in-raster and off-raster synchronization signal blocks (SSBs) for establishing communications with mobile devices and/or user equipment (UE). The SSBs may provide control resource set (CORESET) data used for establishing a communication channel between a UE and an IAB node. The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.

    Abstract: 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.

    Abstract: In NR networks with dynamic TDD operation, two types of cross-link interference (CLI) arise: UE-to-UE and TRP-to-TRP. UE-to-UE CLI measurement and reporting can assist the network in managing CLI. The problem is that, for a cell to be able to measure the CLI reference signal transmitted by UEs in another neighboring cell, the cell needs to know what CLI-RS transmission resources assigned to the UEs in the neighboring cells. Embodiments of the present disclosure provide systems and methods for the exchange of such information between cells. In some embodiments, for example, a gNB sends a request message to a neighboring gNB and the neighboring gNB sends back a response message that includes TDD DL/UL Configurations of its cells and a list of the resources assigned to its UEs for transmission of UE-to-UE CLI reference signal.
