Abstract: Techniques for calibrating a barometer sensor of a user equipment over time are discussed herein. In some cases, the accuracy of the barometer sensor may degrade over time. Techniques can include determining that the UE is at a consistent location over time. When the UE is at the location, the sensor data can be captured over time and stored. Data can be grouped by time periods (e.g., weekly, monthly, etc.) and a metric, such as an average value, can be determined. Over time, metrics can be compared to determine a drift in sensor accuracy. Differences in metrics can be used to determine calibration data, such as an offset, to calibrate subsequent sensor data. The offset can be applied to later-captured sensor data to provide more accurate data, which can ultimately result in more a more accurate determination of an elevation of the UE.

Abstract: Systems and methods are provided for using morphology to determine a confidence level of a civic address associated with an enhanced 911 call. After a request by a public safety answer point (PSAP) for a civic address corresponding to user equipment (UE) initiating a call for emergency services is received at a node, the node receives from the UE a geodetic location corresponding to the UE. The geodetic location corresponding to the UE is utilized to retrieve morphology information from a database. Based at least in part on the morphology information, a confidence level of the civic address can be determined. Upon the confidence level of the civic address satisfying a configurable threshold, the civic address is provided to the PSAP.

Abstract: Methods, systems, and a non-transitory computer-readable medium that provide a sanctuary antenna for mitigating FDD carrier degradation during TDD antenna sharing are provided. The method begins with determining that the carrier degradation will occur during at least one FDD receive signal slot in a FDD frequency band on at least one antenna of the TDD frequency band based on the at least one FDD receive signal slot coinciding with at least one scheduled TDD transmit slot. Then, based on the determining, switching at least one scheduled FDD receive signal slot from the at least one antenna of the TDD frequency band to a sanctuary antenna occurs. The sanctuary antenna is used for a duration of at least one sounding reference signal (SRS) symbol.

Abstract: Emergency alert systems and methods for disabled and/or differently abled persons are disclosed. Upon receiving an alert message, the system translates the alert message to an audio message (text to speech) when the text to speech feature is enabled. In some implementations, the system waits for a threshold period of time (e.g., 30 seconds) to receive a user acknowledgment of the alert message, and translates the alert message to an audio message if no acknowledgment is received within this time. The user acknowledgment can be received via a selection of an option (e.g., by clicking an “OK” button) and/or via an audio option (e.g., by saying “Ok, received”) when the text to speech feature is enabled. The system then outputs (e.g., reads out loud) the translated message so that the disabled or differently abled persons can be informed of the emergency situation. After outputting the translated message, the system can further wait for a user acknowledgment of the translated audio message.

Abstract: A battery control device and a battery capacity estimation method are provided. The battery control device includes a current detector and a processor. The current detector detects the battery. The processor is electrically connected to the current detector. The processor performs coulomb current integration to obtain the integrated value based on a current detection result of the battery detected by the current detector during a sampling period. The processor multiplies the integrated value by a battery coulomb beta coefficient to obtain a depth of discharge. The processor calculates a first relative state-of-charge of the battery according to the depth of discharge and determines remaining battery power information according to the first relative state-of-charge.

After a request by a public safety answer point (PSAP) for a civic address corresponding to user equipment (UE) initiating a call for emergency services is received at a node, the node receives from the UE a geodetic location corresponding to the UE. The geodetic location corresponding to the UE is utilized to retrieve parcel information from a database. Based on a first portion of the parcel information and a comparison of a second portion of the parcel information to the geodetic location, a confidence level of the civic address can be determined.

Abstract: A configurable radio frequency filter is discussed herein. A device can include a filter component that includes multiple filters coupled between a radio frequency integrated circuit (RFIC) and one or more antennas via individual switches. A filter of the filter component may comprise a bandpass filter configured to pass specific frequencies. Filters of the filter component can comprise pass bands that are mutually exclusive or at least partially overlapping. A device can receive a channel allocation in a Citizens Broadband Radio Service (CBRS) band from a Spectrum Access System when initiating a carrier aggregated communication. In response to receiving the channel allocation, the device can select one or more filters of the filter component for filtering signals to and from an antenna component.

Abstract: A network base station can select, for each of one or more attached terminals, a respective downlink transmission mode (DTM) based at least in part on respective channel condition information (CCI). The base station can determine a subframe allocation of DTMs to subframes of a radio frame, and transmit downlink data to terminals based the subframe allocation. Additionally or alternatively, the base station can receive load information from a second base station associated with a different access network and determine the subframe allocation based on the load information. The subframe allocation can associate a specific access network with each subframe. Additionally or alternatively, the base station can send the subframe allocation to the second base station. Additionally or alternatively, the base station can determine a proportion of GBR traffic of a particular DTM, determine a reference-signal transmission rate associated with that DTM, and transmit reference signals accordingly.

Abstract: Systems and methods are provided for determining the quality of a civic address produced by a reverse geocoder, utilizing the uncertainty of a geodetic location and a distance between the geodetic location and a geocoded location (i.e., a civic address) determined by the reverse geocoder. Upon receiving a request by a PSAP for a civic address corresponding to a UE initiating a call for emergency services, a node initially identifies a geodetic location of the UE and an uncertainty of the geodetic location. The node initiates an API call to a reverse geocoder API. The node receives a geocoded location corresponding to the geodetic location and compares the geocoded location to the geodetic location to determine a distance between them. Based on the uncertainty of the geodetic location and the distance between the geodetic location and the geocoded location, a quality of the civic address is determined.

Abstract: Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment to send the earliest available location that the user equipment can come up with, after detecting an emergency message (e.g., detecting a 911 digit string). This can be done by sending the current location of the user equipment via HTTPS protocol to a telecommunications service provider node (e.g., an end point in GMLC). In this manner, the system avoids a major overhaul of the existing 3GPP E911 location standard while allowing timely compliance of the NG911 mandate.

Abstract: Systems, methods, and computer-readable media herein generate an E911 location report based on an uncertainty associated with a device-based hybrid (DBH) location received from a UE device. The uncertainty may be compared to an uncertainty threshold value to determine which values to include in a location report sent to a PSAP. A civic address associated with a UE device may be included in a location report where the uncertainty is sufficiently low, thus a location report can be sent to a PSAP with the most relevant and accurate information so that first responders can more effectively locate a distressed caller.
