Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

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: 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: In a method of device-to-device communication, efficient power management is provided when a primary device has a low battery level. The primary device can send synchronization signals and discovery messages to secondary devices by looping through a sequence of transmit power values in a sequence of consecutive frames, where the sequence of transmitting values includes a default power value and a reduced power value.

Abstract: This disclosure relates to techniques and devices for implementing an emergency power save mode (EPSM) in a user equipment device (UE). A UE may enter the EPSM in response to user input. While operating in the EPSM, the UE may power down a display of the UE to preserve battery life and may broadcast an emergency beacon in response to user input to a hardware button of the UE, such as a volume button. The UE may supply sound or haptic feedback in response to broadcasting the emergency beacon.

Abstract: A method implemented on a mobile device that starts by receiving a temperature reading from a sensor included on the mobile device. The temperature reading is compared to a threshold temperature and a power cap is set when the temperature reading is greater than the threshold temperature. The power cap is a maximum transmission power of the mobile device. The method then determines if the mobile device is transmitting a critical message. The power cap is released for a period of time if the power cap is set and the mobile device is determined to be sending a critical message. Other embodiments are also described.

Abstract: This application describes methods and apparatus to manage data transport across multiple radio links for 5G-capable wireless devices. Under certain criteria, including performance of at least one radio link, a mobility state of a 5G-capable wireless device, and data transport requirements for a latency sensitive application session, the 5G-capable wireless device sends buffer status report (BSR) requests for one or more both of the radio links to prioritize and transition uplink (UL) data between radio links before a measurement reporting threshold is met. In some embodiments, the 5G-capable wireless device proactively sends BSR requests for radio resources before the UL data is generated by the latency sensitive application session. In some embodiments, the 5G-capable wireless device duplicates UL data for the latency sensitive application session across multiple radio links.

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.
