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.

Evolved multimedia broadcast multicast service (eMBMS) streaming loss control in a radio sharing concurrent radio access technology (RAT) capable mobile device

Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing a tune-away by a radio frequency (RF) resource supporting a first subscription to support a second subscription. A device processor may monitor a data loss during a first burst of a segment of a broadcast data stream received using the first subscription by the MSMS communication device. The device processor may calculate a permitted data loss of the segment of a broadcast data stream. The device processor may reserve one or more subframes in a second burst of the segment based on the permitted data loss, and the device processor may prevent a tune-away of the RF resource from the first subscription to the second subscription during the reserved one or more subframes of the second burst.

Managing tune-aways in a multi-subscription multi-standby communication device

Methods and apparatus for selecting one or more suitable antennas for use during power-up/initial acquisition and out of service modes are disclosed. In some examples, initial system acquisition may be performed for a particular receive circuit utilizing a selected one of a first antenna or a second antenna, based on a channel characteristic, such as an automatic gain control (AGC) value corresponding to a received signal energy utilizing either of the antennas. In another example, initial system acquisition utilizing either a receive diversity determination algorithm or an antenna switching determination algorithm may be performed based on a channel characteristic, such as an AGC value corresponding to a received signal energy utilizing one of the antennas coupled to one of the receive circuits.
