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: 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).

Abstract: Methods, systems, and devices for wireless communication are described. A station may be communicating with an access point during a first active communication period. The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.
