Abstract: Techniques for synchronizing wakeup intervals are disclosed. In one example, a first access terminal that has both Bluetooth and Wi-Fi capabilities may include a communication controller that when the first access terminal detects that WLAN connectivity is turned ON, the communication controller adjusts the sniff anchor point for Bluetooth connectivity such that the sniff anchor points are aligned with the WLAN beacon intervals. In another example, the first access terminal has the WLAN connectivity turned ON and connected to an access point before a Bluetooth connection to a second access terminal is established. The communication controller may set the Bluetooth sniff interval and sniff anchor points such that they are in multiple of the beacon interval.

Abstract: A system for performing peak current mitigation in an application programming subsystem (APSS) dynamically performs mitigation based at least in part on power rail voltage and leakage current obtained at boot time. The voltage and leakage current obtained at boot time are used to estimate peak current. A map that is generated prior to boot time maps estimated peak current to throttling level and dictates different levels of throttling to be performed for different ranges of estimated peak current. At boot time, the map is used to map the estimated peak current to a level of throttling to be applied. If conditions at run time indicate that peak current is occurring or is likely to occur soon, the mapped level of throttling is applied to mitigate the peak current.

Abstract: The disclosure generally relates to detecting playback buffer underrun at a sink device to improve streaming media quality. More particularly, according to various embodiments, a media source device may establish a connection with the sink device according to a short-range wireless communication protocol (e.g., Bluetooth) and stream multimedia data to the sink device over the established connection. The sink device may then store the streamed multimedia data in a playback buffer, render the streamed multimedia data from the playback buffer, and send a signal to the source device to indicate a status associated with the playback buffer. Accordingly, the source device may increase local resources allocated to streaming the multimedia data to the sink device in response to the status signal indicating an underrun condition in the playback buffer at the sink device (e.g., where the buffered multimedia data stored therein has fallen below a threshold).
