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: 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: 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: 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.

Abstract: Technology is disclosed for a relay node (RN) operable for backhaul beam failure recovery (BFR) in a fifth generation (5G) new radio (NR) integrated access and backhaul (IAB) network. The relay node can be configured to: decode a periodic reference signal for beam failure instance detection received from a donor node (DN); identify abeam failure between the RN and the DN, wherein the beam failure occurs when N beam failure instances are identified, wherein N is a positive integer; identify whether a candidate beam of one or more candidate beams at the RN has a reference signal greater than a threshold; prepare a BFR request; and encode the BFR request.

Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.

Abstract: Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (Beam Failure Recovery) and RLF. A first mechanism that can be employed in various embodiments can perform one or more RLF-related actions (e.g., stopping a T310 timer, resetting a N310 counter) upon BFR success. A second mechanism that can be employed in various embodiments can comprise revising one or more RLF parameters (e.g., N310, N311, T310, Out-of-sync threshold, in-sync threshold, etc.) based on the presence of a strong BFR mechanism.

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: 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.
