Aspects presented herein may enable a UE to reduce sensor initialization time for one or more sensors that are to be used for DR positioning during a GNSS signal outage. In one aspect, a UE initiates a first positioning engine based on an availability of a GNSS signal, where the first positioning engine measures a relative position of the UE without ambiguity processing. The UE calibrates at least one IMU sensor based on the relative position of the UE measured by the first positioning engine. The UE performs a positioning calculation of the UE via the at least one IMU sensor in response to the GNSS signal being unavailable.

Fast sensor initialization

Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.

Using doppler for multipath detection and mitigation in RF-based positioning

Aspects presented herein may improve the positioning accuracy and latency of a positioning engine that receives at least one position constraint for assisting the positioning. A wireless device obtains an indication of at least one position constraint for a positioning engine. The wireless device detects whether the at least one position constraint exceeds an error threshold based on a set of PR residuals between the wireless device and at least one satellite. The wireless device excludes the at least one position constraint from a calculation at the positioning engine if the at least one position constraint exceeds the error threshold, or includes the at least one position constraint in the calculation at the positioning engine if the at least one position constraint is below the error threshold.

Precise positioning engine

An example method performed at a mobile device for determining a position may comprise receiving correction data associated with (1) a first pseudorange measurement of a first GNSS signal sent from a satellite vehicle on a first GNSS carrier frequency and (2) a second pseudorange measurement of a second GNSS signal sent from the satellite vehicle on a second GNSS carrier frequency. The method also may comprise measuring a third GNSS signal sent from the satellite vehicle and received at the mobile device on a third GNSS carrier frequency, to generate a third pseudorange measurement. The method also may comprise determining the position of the mobile device using (a) the third pseudorange measurement of the third GNSS signal on the third GNSS carrier frequency and (b) the correction data associated with the first pseudorange measurement and the second pseudorange measurement.

Cross-frequency correction for precise positioning

Described are methods, systems, and devices for correcting ionospheric error. In some aspects, a mobile device equipped with a Global Navigation Satellite System (GNSS) receiver is configured to determine a positioning measurement of a GNSS signal. The mobile device is further configured to receive augmentation data from an augmentation system. When the mobile device is unable to obtain newer augmentation data, the mobile device can instead obtain augmentation data associated with historical Total Electron Content (TEC) values. In such instances, the augmentation data will have been generated to represent ionospheric delay during a time period that ended before the augmentation data is obtained. Based on the augmentation data associated with historical TEC values and a pierce point of the received GNSS signal, an ionospheric error in the positioning measurement of the GNSS signal can be determined and corrected.

Ionosphere grid history and compression for GNSS positioning

A tracking module processes the determined correlations to track a carrier of the received composite signal for estimation of a change in phase over a time period between a receiver antenna and one or more satellite transmitters that transmit the received signal as the receiver changes position with respect to an initial position during the time period. A relative position estimator estimates the relative position of the navigation receiver with respect to an initial position over the time period time by time-differencing of the phase measurements of the one or more tracked carrier signals. Bias estimators can estimate or compensate for errors in initial position and temporal changes in receiver clock and tropospheric delay.

Satellite navigation receiver for relative positioning with bias estimation

In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

Detecting spoofed global navigation satellite system (GNSS) signals

System and method embodiments for analyzing a test fluid to detect prior or present infestations of bed bugs are described. In an embodiment, the method may include receiving the test fluid on a test strip within the detection device. The test strip may include a reaction portion and a reagent portion containing an antibody or antigen-binding fragment that is conjugated to a colored particle. The test fluid may include bed bug antigen that reacts with the conjugated antibody. The detection device may include a first and a second optical sensor for monitoring a reaction and a background color intensity, respectively. Upon a predetermined time delay elapsing, the detection device determines whether bed bug antigen is present in the test fluid using the monitored color intensities and minimum and maximum color intensity thresholds associated with bed bugs. Then, the detection device outputs a result using a visual display.

Bed bugs detection device

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Minimization of drive test for dual connectivity

Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

Measurement disabling in frequency ranges

Techniques for Ultra Wide-Lane (UWL) Real-Time Kinematic (RTK) positioning a mobile device may include obtaining, using a multi-band GNSS receiver of the mobile device: a first carrier-phase measurement of a first GNSS signal on a first GNSS carrier frequency, and a second carrier-phase measurement of a second GNSS signal on second GNSS carrier frequency. Techniques may further comprise providing a position estimate of the mobile device, wherein: the position estimate is determined from a wide-lane (WL) combination of the first carrier-phase measurement and the second carrier-phase measurement, and the WL combination has a combined carrier phase noise that is less than a pseudo-range noise of the first carrier-phase measurement and a pseudo-range noise of the second carrier-phase measurement.
