  • Publication number: 20150131461
    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.

  • Publication number: 20150133061
    Abstract: Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.

  • Publication number: 20150119103
    Abstract: Methods, systems and devices for prioritizing communication technologies to allocate resources in a mobile device. The mobile device may employ a dual subscription, dual active (DSDA) configuration in which two subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may identify current states that indicate the type of communications associated with the subscriptions. In an embodiment, an applications processor within the mobile device may perform the state identifications. The mobile device may determine priorities of the concurrently active subscriptions based on the identified states. In an embodiment, the priorities may be determined by a modem processor within the mobile device. When the priorities are determined to be the same, the mobile device may perform a tiebreaker algorithm to further identify priorities. Based on the determined priorities, the mobile device may allocate resources to favor the subscription with the higher priority.

  • Patent number: 8976740
    Abstract: A method of wireless communication includes acquiring at least one non-required system information from a cell while in a radio resource control connected state. The non-required system information is system information that is not required in the radio resource control connected state. The method includes transitioning from the radio resource control connected state to a radio resource control idle state on the cell without acquiring the at least one non-required system information.

  • Publication number: 20150063216
    Abstract: A system, a method and an apparatus are described. The apparatus comprise a modem that determines frequencies at which a transceiver of a wireless device is susceptible to interference generated by a different transceiver of the wireless device, and that modifies a search for a radio access network based on the one or more frequencies. The first transceiver may be susceptible to the interference by means of transmission of the interference through one or more circuits within the wireless device. A threshold power level may be modified based on an estimate of the power of the interference. The threshold power level may be used to determine presence of a pilot signal. The interference may be modeled based on a list of frequencies associated with one or more subscriptions of the wireless device. An order of searching for pilot signals may be modified.

  • Publication number: 20150006677
    Abstract: A system includes a ratings server that receives the list of top applications from a source external to the ratings server and selects at least a subset of the top applications based at least in part on a rank of each of the top applications in the list. The system further includes a test server that tests at least one characteristic of each of the subset of top applications selected by the ratings server and outputs a rating representing the at least one characteristic. The ratings server determines a behavior of each of the subset of top applications based on the rating and publishes the behavior of the subset of top applications for access by a user over a communication network.

  • Patent number: 8830214
    Abstract: A technique for managing image quality in a laser-based imaging system is provided. Laser light sources are organized into two or more groups, and optical output power of a light source group containing an under-performing laser is matched to that of the under-performing laser, while the optical output power of the light sources in the remaining groups is not. The output of the laser light sources in each group is interleaved with the output of the laser light sources in the other groups, so that perceptual uniformity of a displayed image is maintained when the display is viewed from an appropriate viewing distance.

  • Publication number: 20140213210
    Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.

  • Publication number: 20140200685
    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.
