Abstract: Methods, circuitries, and systems are provided for performing frame based equipment channel sensing in unlicensed spectrum. In one example, a user equipment (UE) device includes a processor configured to perform operations including receiving, from a base station (BS), a plurality of UE-Initiated channel occupancy time (COT) frame based equipment (FBE) configurations; performing UE-Initiated COT FBE channel sensing based on a selected one of the received plurality of UE-Initiated COT FBE configurations to acquire a COT; and transmitting data during the COT.

Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.

Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

Abstract: A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.

Abstract: Methods, circuitries, and systems are disclosed for configuring multiple PDSCH/PUSCH transmission with repetition of each transmission. In one example, a method includes receiving, from a base station, control information that indicates i) time domain resources for communication of at least two physical downlink shared channel (PDSCH) or at least two physical uplink shared channel (PUSCH) transmissions and ii) at least one repetition number indicating a number of times each of the at least two PDSCH/PUSCH transmissions is repeated. The method includes configuring operation to receive the at least two PDSCH transmissions or to transmit the at least two PUSCH transmissions based on the time domain resources and repetition number.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A base station can poll user equipment (UE) by transmitting a downlink control information (DCI) or other downlink communication that indicates resources that a UE can use to send a scheduling request. The resources are dynamic, e.g., they can be updated and allocated to UEs based on network conditions. Other aspects are described.

Abstract: Apparatuses, systems, and methods for overhead reduction for multi-carrier beam selection and power control. A user equipment device (UE) may receive an uplink beam configuration for a group of component carriers and may communicate using the uplink beam configuration for the group of component carriers. The UE may receive an updated uplink beam configuration for the group of component carriers. The update uplink beam configuration may include a medium access control (MAC) control element (CE) that may update a pathloss reference signal for the group of component carriers. The MAC CE may include an indication of a spatial relation for aperiodic or semi-persistent sounding reference signals for the group of component carriers, an indication of a transmission control indicator for a physical downlink control channel, an indication of an update for a physical uplink shared channel, and/or an indication of an update for a sounding reference signal.
