    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: Some embodiments of this disclosure include apparatuses and methods for physical downlink control channel design for a discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. The apparatuses and methods can include at least operating a base station (BS) to generate one or more physical downlink control channels (PDCCH) in a time division multiplexing (TDM) manner using a Discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform, generate a demodulation reference signal (DMRS) which is multiplexed in the TDM manner with the one or more PDCCH, and transmit the one or more PDCCH and the DMRS to a user equipment (UE).

    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: 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.
