Abstract: In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.

Abstract: In an aspect, a communications node selects a reference device for a positioning procedure based on hardware group capabilities associated with reference devices involved in the positioning procedure (e.g., RTT, differential RTT, double differential RTT, TDOA, etc.). In another aspect, a distance between reference devices is estimated based on timing measurements of reference signal(s) for positioning. A hardware group delay associated with the reference devices is estimated based on (i) the estimated distance between the first and second reference devices, and (ii) a known distance between the first and second reference devices.

Abstract: Certain aspects of the present disclosure provide techniques for selecting an antenna configuration for transmitting in a wireless communication network. An example technique may include determining that a front guard period is not scheduled between a scheduled uplink transmission and a scheduled sounding reference signal (SRS) transmission, and based on the determination, transmitting the scheduled SRS transmission using a first antenna configuration after transmitting the scheduled uplink transmission using the first antenna configuration.

Abstract: Methods, systems, computer-readable media, and apparatuses for UE positioning are described. In some embodiments, a UE is configured to transmit a reference signal to a network resource for performing measurements on the reference signal and deriving the position of the UE. The timing of the reference signal is tracked at a particular precision. The precision is based on a timing accuracy that the UE can support from different timing accuracies. The different timing accuracies may be supported, each of which may have a different set of timing error limits. For example, for an angular-based positioning of the UE, a low timing accuracy may be supported. In comparison, for a timing-based positioning method, a high timing accuracy may be supported.

Abstract: A method of initiating positioning reference signal exchange includes: determining, at a first user equipment, a null-zone presence of the first user equipment, the null-zone presence of the first user equipment being at least one of a current presence of the first user equipment in a null zone or a future presence of the first user equipment in the null zone; and transmitting, from the first user equipment and in response to determining the null-zone presence of the first user equipment, a request for positioning reference signal exchange between the first user equipment and a second user equipment separate from the first user equipment.

Abstract: Techniques for communication by a user equipment (UE) are disclosed. Techniques can include determining a positioning state information (PSI) report to transmit, where the PSI report comprises positioning-related information, and selecting a physical uplink control channel (PUCCH) resource with which to transmit the PSI report, where the selected PUCCH resource comprises a number of resource blocks (RBS). Techniques can further include determining whether to transmit the PSI report using the selected PUCCH resource, based on: the number of RBS, a size of uplink control information (UCI) to be transmitted using the selected PUCCH resource, the selected PUCCH resource being configured with a capability to include both the PSI report and a hybrid automatic repeat request acknowledgment (HARQ-ACK), or the selected PUCCH resource being configured to include only one or more PSI reports, and optionally one or more CSI reports, as a payload, or any combination thereof.

Abstract: Disclosed are techniques for reducing overhead of low layer positioning reports. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode determines that the UE is not expected to wake up during a next DRX ON duration of a DRX cycle; determines, based on one or more factors, whether to wake up during the next DRX ON duration to transmit a positioning measurement report or an uplink positioning reference signal (UL-PRS); and based on the determination: wakes up and transmits the positioning measurement report or the UL-PRS during the next DRX ON duration, or remains in a DRX sleep state and refrains from transmitting the positioning measurement report or the UL-PRS during the next DRX ON duration.

Abstract: A method of wireless communications by a user equipment (UE) determines whether a downlink positioning reference signal (PRS) overlaps in time with an uplink transmission within a full duplex slot. The method adjusts the uplink transmission to address the overlap. The adjusting can use an uplink grant to achieve a gap between the PRS and the uplink transmission. The adjusting can puncture a number of resource elements assigned for the uplink transmission. The resource elements are positioned adjacent to the PRS. The adjusting can reduce transmit power. The method can include receiving a priority order for the PRS and multiple uplink transmission types. In this case, the adjusting comprises dropping the uplink transmission in accordance with the priority order.

Abstract: Disclosed are techniques for reducing the overhead of low layer positioning reports. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one transmission-reception point (TRP) during a positioning session, and reports, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a network entity, one or more capability messages indicating one or more capabilities of the UE to process positioning reference signals (PRS), the one or more capabilities indicating at least a duration of PRS that the UE can process within a measurement window without a measurement gap, and performs one or more positioning measurements of one or more PRS resources during the measurement window up to the duration of PRS.
