  • Patent number: 12238744
    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.

  • Patent number: 12149461
    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.

  • Patent number: 12132528
    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.

  • Patent number: 12082228
    Abstract: Provided herein are systems and methods of configuring received signal strength indicator (RSSI) measurements to determine crosslink interferences (CLI). For instance, a user equipment (UE) can receive, using radio front-end circuitry, a RSSI resource configuration for CLI measurement from a base station in a 5G network. The UE can then measure a RSSI of one or more received signals based at least in part on the RSSI resource configuration. The UE can then perform one or more CLI measurements based at least in part on the measured RSSI. The RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs.

  • Patent number: 12068796
    Abstract: Apparatuses, methods, and computer-readable media are provided for determination of reference signal received power (RSRP) to estimate cross-link interference. The approach uses a received signal from a second UE and downlink (DL) timing information from a transmission reception point (TRP). The approach generates a corrected timing signal based on the received signal, the DL timing information and a reference sequence, and then extracts a symbol from the received signal and the corrected timing signal. The approach then transforms using a fast Fourier transform (FFT) circuit the symbol, and then cross-correlates with a reference sequence to generate a correlation result from which the RSRP is estimated.

  • Patent number: 11985619
    Abstract: In a wireless communication environment, there may arise a timing misalignment for SRS-RSRP measurement. In order to address this issue, a UE may receive an uplink transmission from second UE containing the uplink transmission timing for the first UE. The UE may then set its measurement timing to be the same as the uplink transmission timing. The UE then carries out SRS-RSRP measurement according to the newly-set measurement timing.

  • Patent number: 11855763
    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.
