Abstract: Positioning measurements to determine the location of a user equipment (UE) may be obtained within a configured time window, such as a measurement time window or positioning reference signal (PRS) processing window. If one or more position measurements cannot be obtained within the configured window, the measuring entity may provide an error report to the positioning entity indicating that it was unable to obtain one or more positioning measurements within the configured time window. The error message may be provided in the provide location information report. The error message may include the timing of the error within the configured time window, e.g., whether the error occurred at the beginning or end of the configured time window. The error message may further indicate the cause of the error, such as failure to receive a PRS processing window, or that the PRS had low priority relative to downlink signals or channels.

Abstract: A positioning reference signal measurement method includes: receiving, at a user equipment from a network entity, an OFDM PRS (orthogonal frequency division multiplexing positioning reference signal) comprising a first set of first OFDM symbols that are consecutive and include a first center symbol and at least one pair of first side symbols disposed symmetrically about the first center symbol and having identical resource element sounding patterns; combining the first side symbols in each of the at least one pair of first side symbols to produce at least one first combined symbol; and determining a measurement of the OFDM PRS based on the at least one first combined symbol and the first center symbol.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration indicating one or more PRS resources to be measured by the UE, transmits, to a base station serving the UE, measurement report payload related information based on the PRS configuration, obtains positioning measurements of the one or more PRS resources, transmits a scheduling request (SR) to the base station, the SR requesting an uplink grant for a measurement report for the positioning measurements, receives the uplink grant from the base station in response to the SR, the uplink grant indicating uplink resources on which to transmit the measurement report, and transmits at least a portion of the measurement report to the base station on the uplink resources indicated by the uplink grant.

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: Aspects presented herein may enable a network entity to associate one or more positioning related parameters between a UE and an NTN base station with a scheduling offset, a position of the NTN base station, and/or a time. In one aspect, a network entity identifies a scheduling offset that is associated with an NTN base station. The network entity transmits, to a UE communicating with the NTN base station, one or more of: a set of expected RSTD values associated with the NTN base station, a set of compensation factors associated with the set of expected RSTD values, a set of uncertainty values associated with the set of expected RSTD values, a set of expected DL-AoD values/uncertainties associated with the NTN base station, or a set of expected AoA values/uncertainties associated with the NTN base station, where one or more of these parameters are derived based on the scheduling offset.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network node transmits, to a network entity, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and measures the one or more first PRS resources having the one or more physical layer security properties. In an aspect, a network entity receives, from a first network node, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and transmits, to a second network node, a request for the second network node to transmit the one or more first PRS resources having the one or more physical layer security properties to the first network node.
