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: 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.

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.

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.
