Abstract: A method for supporting radar operations may involve providing, from a radar server, one or more transmit beam parameters, over one or more wired or wireless interfaces, to a first wireless communications system Transmission Reception Point (TRP) for configuring a transmit beam for sending a transmit signal from the first wireless communications TRP. The method may further involve providing, from the radar server, one or more receive beam parameters, over one or more wired or wireless interfaces, to a second wireless communications system TRP for configuring a receive beam for receiving, at the second wireless communications system TRP, an echo signal from one or more targets as a reflection of the transmit signal. The first wireless communications system TRP and the second wireless communications system TRP may be part of a wireless communications system.

Abstract: A muting configuration for downlink positioning reference signals (PRS) is based on the slot type in which the PRS is transmitted. A slot type muting configuration mutes PRS if the PRS are transmitted in a full duplex slot, such as an in-band full duplex slot. If the PRS are transmitted in a sub-band full duplex slot, the PRS may be muted depending on whether the base station is capable of self-interference cancellation. The slot type muting configuration does not mute the PRS transmission in a half-duplex slot. The slot type muting configuration may be dynamic and may be provided to a user equipment (UE) in lower layer signaling to improve latency. The slot type muting configuration may be combined with other types of muting configurations, such as inter-instance muting, intra-instance muting, and intra-slot muting, e.g., using a logic function to combine the configurations.

Abstract: According to embodiments herein, the use of an SL interface in the positioning of a UE can include additional reporting from the UE or an anchor UE related to a reference signal sent via the SL interface. This information can include information regarding the received power and/or timing of the reference signal, the angle at which it was received, and orientation of a receiving UE, and various other considerations that may not be needed in a Uu interface with a base station.

Abstract: According to embodiments herein, assistance data may be provided to a UE regarding an anchor UE that provides a reference signal via the SL interface to the UE. Assistance data may include information indicative of the coordinates, height, drift rate, beam characteristics, group delay, and/or other aspects of the anchor UE. The assistance data may be provided to the UE by a location server, a base station, or directly from the anchor UE.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a serving base station, in one or more active bandwidth parts (BWPs) of the UE, a request for a no-downlink-scheduling gap, the request including at least time-domain parameters related to scheduling the no-downlink-scheduling gap, receives, from a neighboring base station, in the one or more active BWPs, a downlink positioning reference signal (DL-PRS) during the no-downlink-scheduling gap, and transmits, in the one or more active BWPs, an uplink positioning reference signal (UL-PRS) during the no-downlink-scheduling gap in response to reception of the DL-PRS.

Abstract: In an aspect, a UE obtains a plurality of positioning reference signal (PRS) configurations. The UE receives, from a BS, an L1 or L2 message that indicates one of the plurality of PRS configurations, which in turn triggers an aperiodic or semi-periodic PRS procedure in accordance with the indicated PRS configuration.

Abstract: In an aspect, a UE determines a power consumption of the UE for a position estimation procedure based on a set of power consumption parameters associated with the UE, the set of power consumption parameters comprising one or more layer-specific parameters associated with a set of positioning frequency layers (PFL), a Positioning frequency layer processing capability of the UE, a positioning reference signal (PRS) resource processing capability of the UE, a PRS measurement type capability of the UE, a positioning session processing capability of the UE, or a combination thereof. The UE performs one or more positioning measurements associated with the position estimation procedure in accordance with the determined power consumption.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration. The UE receives, from a serving base station, a measurement gap (MG) configuration. The UE determines that one or more transmission properties of one or more resources should be modified and transmits PRS modification information to the network entity based on the one or more transmission properties of one or more PRS resources to be modified. The network entity may be a location server or location management function.

Abstract: A target user equipment (UE) identifies other UEs that are available for a positioning reference signal (PRS) exchange for sidelink assisted positioning of the target UE. The target UE may provide to a network entity, such as a location server, the identifications of the UEs that are available for the sidelink-assisted positioning of the target UE. The network, entity may generate and provide for sidelink-assisted positioning the PRS configurations for UEs, which may include the one or more UEs recommended by the target UE. The target UE may provide a list of UEs, in response to a request from the network entity, in response to receipt of a network generated list provided to the target UE, or in response to a determination that PRS measurements based on previously acquired UE PRS configurations are inadequate. The sidelink-assisted positioning may be used when the target UE is present in a null-zone.
