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: A user equipment (UE) is configured to establish network connections for long-term evolution (LTE) and new radio (NR) radio access technologies (RATS) in non-standalone (NSA) E-UTRA-NR dual connectivity (ENDC) operation. The UE includes a multi-antenna array for data and signaling transmissions and receptions over the LTE and NR connections. The UE determines a most efficient antenna of the multi-antenna array for an operating frequency band of the LTE and NR connections, wherein the most efficient antenna is determined based on at least one performance factor for the UE when using the antenna compared to other antennas of the multi-antenna array, evaluates one or more factors for determining whether the LTE RAT or the NR RAT is to use the most efficient antenna and transmits uplink data on the most efficient antenna via either the LTE RAT or the NR RAT based on the evaluated factors.

Abstract: A user equipment (UE) may skip certain measurements when it is unlikely that the UE will use the measurements. The UE determines that the UE is configured with one of a measurement gap or gapless measurements, identifies that a predetermined condition has been satisfied and implements a mitigation technique in response to identifying that the predetermined condition has been satisfied, wherein the mitigation technique includes omitting performing one of a measurement during the measurement gap or a gapless measurement, wherein the measurement or the gapless measurement corresponds to a first radio access technology (RAT) that is different than a second RAT on which the UE is currently camped.

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.

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: 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.
