    摘要： 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.

    摘要： 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).

    摘要： 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.

    摘要： 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.

    摘要： Systems and methods are provided for increasing paging opportunities when the unlicensed band is used. A user equipment (UE) may determine a plurality of different paging occasions (POs) to monitor per DRX cycle. The plurality of different POs corresponds to beam sweep repeats for a first set of UEs in an unlicensed band from a base station in a wireless network. The UE monitors the plurality of different POs to receive the paging message from the base station. The plurality of different POs may include respective physical downlink control channel (PDCCH) monitoring occasions. The plurality of different POs may include at least two consecutive POs associate with the first set of UEs within a same paging frame. Alternatively, the plurality of different POs may include at least two non-consecutive POs associated with the first set of UEs separated by at least cycle one other PO associated with a second set of UEs.
