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: A wireless device may connect, using a first subscriber identity module (SIM), to a first base station according to a first radio access technology (RAT) and a second base station according to a second RAT. The wireless device may also connect, using a second SIM, to a third base station according to the first RAT. The wireless device may, in response to the second SIM performing a call according to the first RAT, disable the first RAT for the first SIM and perform, using the first SIM, data communication according to the second RAT while the call is performed using the second SIM.

Abstract: Techniques described herein includes solutions for mitigating interference related to antenna switching. A user equipment (UE) may determine a potential for interference to data reception on a second frequency band due to antenna switching associated with transmission of reference signals on a first frequency band. In response to the determination, the UE may select one or more interference mitigation measures based on an operating mode of the UE and one or more UE parameters. An interference mitigation measure may include backing off on a reported value, such as a channel quality indicator (CQI), rank indicator (RI), or reference signal received power (RSRP). The interference mitigation measure may further include skipping reference signal transmission on the first frequency band and the antenna switching associated therewith.

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.

CPC classification number: H04W72/0453
Abstract: This disclosure provide various techniques for decreasing the time it takes user equipment to tune away from a compromised network connection. By more quickly detecting a signal characteristic issue (e.g., signal quality issue) in the compromised signal and performing mitigation actions, the user equipment may decrease power consumption and increase data throughput. The signal quality issue may be detected by monitoring the location of the user equipment, a channel impulse response of the user equipment, and/or a block error rate (BLER) of a signal, among other methods. The data obtained may be fed into confidence validation logic, which may determine a level of confidence that the signal quality issue may cause a weak or broken connection between the user equipment and a network. The confidence validation logic may, based on the determination, operate the user equipment in an active state, a suspend state, or a release state.
