Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.

Abstract: This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

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 power control method for device-to-device communication includes dynamically backing off transmit power value for synchronization signals and discovery messages when the distance between the two devices is less than a pre-determined threshold. The threshold distance may correspond to a distance where the receive power may exceed a pre-determined value. Embodiments may loop the transmit power of synchronization signals between a default transmit power value and backed-off values in consecutive slots of each frame.
