Abstract: Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.

Abstract: Methods, systems, and devices are described for managing power of a user equipment (UE). A UE modem may determine the state of charge of the battery to determine that the battery is in one of two or more charge state levels, and may invoke one or more modem power saving modes based on the charge state level. Power saving modes may include, for example, reducing a number of available receive chains in a UE, initiating a time delay between one or more frequency scan requests performed by the UE, reducing a rate of neighbor search requests performed by the UE, providing a buffer status report (BSR) parameter that indicates a reduced amount of buffer data relative to an actual amount of buffer data for the UE, and/or adjusting a maximum transmit power level for an uplink channel.

Abstract: Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.

Abstract: A system, a method and an apparatus are described. The apparatus includes a modem that responds to a thermal mitigation request by invoking different levels of thermal mitigation for different concurrently active connections. In some instances, the modem may invoke thermal mitigation with respect to a first active connection and refrain from invoking thermal mitigation with respect to a second active connection maintained by the modem. The apparatus determines the first and second active connections based on subscriptions corresponding to subscriber identification modules, an identification of a power amplifier or group of power amplifiers responsible for a thermal issue in the modem. The selection of mitigation levels for each active connection and decisions to invoke mitigation on one connection while refraining from invoking mitigation on another connection may be based on priorities of the active connections, including quality of service related priorities.

Abstract: A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

Abstract: Methods, apparatus, and computer program products for managing mobility in a multi-radio device are provided. One example method generally includes detecting that a first channel is not usable for communicating via a first radio access technology (RAT); receiving a message to redirect from a second channel to the first channel; determining the first channel is in a set of one or more blocked channels not usable for the first RAT; and in response to the determination, taking one or more actions. Another example method generally includes detecting that a first channel is not usable for communicating via a first RAT and providing an indication to a network that a user equipment (UE) no longer supports the first channel.
