Abstract: An electronic device may detect a message request to send one or more redundant messages to a response network. The one or more messages may contain information previously sent from the electronic device to the response network. The electronic device may determine an entropy factor corresponding to the relatedness of the one or more messages to previously sent messages, and the electronic device may send one or more redundant bits in the place of the one or more messages if the entropy factor is below a threshold value corresponding to network resources.

Abstract: Methods and devices for a user equipment (UE) device to utilize an electronic subscriber identity module (eSIM) to provide backup cellular connectivity for essential services and security enhancements. A UE device receives user input to alter an operational state of the UE. The user input may include removing a physical subscriber identity module (SIM) card installed in the UE or attempting to power off the UE. In response to receiving the user input, an authorization process is initiated. In response to determining that the authorization process has failed, a security enhancement is implemented for the UE.

Abstract: A communications network may include user equipment that communicates with external equipment. The user equipment may include an antenna, measurement circuitry, control circuitry, and a display. The antenna may receive downlink signals while the user equipment moves through a geographic area. The measurement circuitry may gather wireless performance metric data from the received signals. The control circuitry may determine whether the gathered wireless performance metric data exceeds, for a predetermined time period, a threshold value. The control circuitry may store respective geographic locations of the user equipment at each location in the geographic area where the gathered wireless performance metric data exceeds, for the predetermined time period, the threshold value. The control circuitry may, in response to a trigger condition, control the output device to produce an output that identifies at least one of the stored geographic locations to a user of the user equipment.

Abstract: This disclosure relates to methods and devices for transmitting acknowledgment messages on a preferred cell in a carrier aggregation scenario. A user equipment device (UE) establishes a connection with a primary cell and one or more secondary cells, and determines a preferred cell from among the primary cell and the one or more secondary cells based at least in part on one or more quality metrics. The UE may determine the preferred cell at least in part in response to determining that transmission power of the UE has been limited due to a specific absorption rate (SAR) backoff feature of the UE. The UE transmits a notification to a network indicating that the UE intends to transmit an acknowledgement message to the preferred cell, and transmits the acknowledgment message to the preferred cell.

Abstract: In a method of device-to-device communication, a user device initially sends an emergency message repeatedly at a first repeating frequency. When a specified number acknowledgement (ACK) messages are received, the user device sends the emergency message repeatedly at a reduced repeating frequency. The repeating frequency may be further reduced when more ACK messages are received.

Abstract: Methods and apparatus to mitigate radio frequency interference generated by hardware circuitry and received by wireless circuitry of a wireless communication device are described. A processor obtains a set of wireless performance metrics for signals received by the wireless circuitry. The processor determines a preferred operating mode for the hardware circuitry based on the set of wireless performance metrics and provides an indication of the preferred operating mode to the hardware circuitry. The hardware circuitry is configured for operation in accordance with the preferred operating mode. The processor and/or a second processor provide an indication to the wireless circuitry when the hardware circuitry initiates and terminates an operation that can cause radio frequency interference into the wireless circuitry. The wireless circuitry is configured during a time period that the hardware circuitry is operational to mitigate effects of radio frequency interference generated by the hardware circuitry.

Abstract: While a circuit service, CS, call is in progress, a request for a packet service, PS, call is received from a background task that is running in the mobile communications user equipment. In response to receiving the request, several air interface parameters that relate to the in-progress CS call are evaluated, in order to decide whether or not to block the PS call based on the evaluation. Other embodiments are also described and claimed.

Abstract: Embodiments are disclosed for selecting locations for transmitting emergency beacons. In an embodiment, a method comprises: determining a current location of a mobile device in a geographic area; configuring a transmitter of the mobile device for device-to-device (D2D) communication; determining one or more candidate transmit locations for D2D communication, wherein each candidate transmit location is determined based at least in part on its elevation, proximity to a D2D device density location that is within a maximum communication distance from the candidate transmit location, and an availability of a trail or path to the candidate transmit location; receiving input selecting a particular candidate transmit location from the one or more candidate transmit locations; in accordance with the input, determining a route from the current location of the mobile device to the particular candidate transmit location; and presenting the route through an output device.

Abstract: Techniques, described herein, may enable a vehicle to engage in vehicle-to-everything (V2X) communications via PC5 sidelink (SL), even when the vehicle does not have a global positioning system (GPS) or other type of satellite signal. While receiving a satellite signal, the vehicle may pre-store future geographic locations based on a travel route and upon detecting a loss of the satellite signal, the vehicle may estimate a geographic location of the UE based on one or more types of information, such as mapping or navigation capabilities of the UE, a travel time since the signal failure or last estimated geographic location, a travel velocity since the since the signal failure or last estimated geographic location, etc. The vehicle may determine, based on an estimated geographic location, that physical resources are appropriate for SL communications and begin using the physical resources accordingly.

Abstract: Methods, devices, and apparatus to adapt operating parameters for satellite signal reception and transmission by a wireless device to mitigate effects of fading due to specular reflections are described herein. The wireless device measures received signal power levels and compares characteristics of the measurements over an observation duration to at least one fading criteria to determine whether to operate in a normal or adaptive mode. While operating in the adaptive mode, the wireless device alternates between high performance mode time periods and low performance mode time periods. The wireless device indicates to a ground station associated with the satellite in which operating mode the wireless device is operating via an uplink data message transmitted during a data cycle at the start of a high or low performance mode time period. The ground station schedules data transmissions accordingly during subsequent data cycles of the high or low performance mode time periods.
