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: 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 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: An approach is described of an access node that is configured to exchange intended Uplink (UL)/Downlink (DL) direction information for cross-link interference (CLI) management in a wireless communication system. The access node includes processor circuitry and communication circuitry. The processor circuitry is configured to generate a message including the intended UL/DL DL direction information. The communication circuitry is coupled to the processor circuitry, and configured to transmit the message to a second access node to thereby implement CLI management.

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.
