Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.

Abstract: In at least one embodiment, a user equipment (e.g., a mobile device) may receive a location request message from a server (e.g., a Location Management Function), wherein the location request message identifies a plurality of Quality of Service parameters for the LTE Positioning Protocol (LPP) positioning session. In at least one embodiment, the user equipment may receive a selection of one or more Quality of Service parameters for the LPP positioning session. In at least one embodiment, the user equipment may configure the user equipment according to the one or more selected Quality of Service parameters. In at least one embodiment, the user equipment may generate a location response message according to the selected QoS parameters. The user equipment may send the location response message to the server. A UE can select the QoS parameters during communication with a server and/or with a second UE via sidelink communications.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE obtains measurement data associated with at least one PRS. The UE transmits, to a BS in a first L1 or L2 PSI report opportunity, a first PSI report indicative of a first set of measurement values associated with the at least one PRS based on the measurement data. The UE further transmits, to the BS in a second L1 or L2 PSI report opportunity that is subsequent to the first L1 or L2 PSI report opportunity, a second PSI report that is indicative of a second set of measurement values associated with the at least one PRS based on the measurement data, the second set of measurement values being refined from the first set of measurement values.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless devices may support a prediction capability for prediction-based control information. A first device may receive, from a second device, first control signaling that activates the predication capability of the first device to generate a set of one or more control parameters for communications. The second device may transmit second control signaling to the first device to indicate initial values of the control parameters and a channel condition model for the first device. The first device and the second device may generate a set of multiple values associated with the control parameters over a time period based on the initial values of the control parameters and the channel condition model. The first device and the second device may communicate during at least the time period according to the set of generated values associated with the control parameters.

Abstract: Disclosed are techniques for wireless communication. 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 a transmission-reception point (TRP) during a positioning session, reports, to a positioning entity, a value of the at least one positioning measurement via low layer signaling, and determines a timestamp for the at least one positioning measurement relative to a reference point, wherein the timestamp comprises an amount of time between the reference point and a time at which the at least one positioning measurement is valid.

Abstract: In an embodiment, a first node (e.g., a UE or a BS) performs a channel response measurement on a reference signal for positioning (e.g., UL reference signal such as SRS for positioning, or a DL PRS). The first node determines, for each of a plurality of peaks detected within the channel response measurement, peak-specific information comprising at least peak magnitude data that is based on a peak magnitude relative to a reference value. The first node reports the peak-specific information for the plurality of peaks to a second node (e.g., a BS, UE, or LMF). The second node receives the peak-specific information, and determines a positioning estimate for a UE based on the peak-specific information.

Abstract: Disclosed are various techniques for wireless positioning. In an aspect, the time that a user equipment (UE) spends on performing positioning reference signal (PRS) measurements is reduced, by lengthening the PRS measurement period (P) and/or by reducing the PRS symbol duration (K). These modifications may be performed by the UE or by a location management server or other network node and may be made in consideration of the UE's mobility status and other environmental or operating conditions of the UE. In an aspect, a network entity may determine P and K to be used by the UE, and may indicate, to the UE, the P and the K to be used by the UE for measuring at least one PRS. The UE may then use the P and the K for measuring at least one PRS.

Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple instances of aperiodic tracking reference signals (TRSs) that use a same set of large-scale channel properties. If two or more aperiodic TRS transmissions are triggered by downlink control information from a base station with a same transmission configuration indicator (TCI) state, a UE that receives the two or more aperiodic TRS transmissions may measure the multiple instances of the aperiodic TRS transmissions assuming that the same large scale parameters or properties can be inferred from each of the aperiodic TRS transmissions. The UE may then update one or more time tracking parameters, frequency tracking parameters, or combinations thereof, based on the same large scale transmission parameters being used for the multiple instances of the aperiodic TRS transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.
