Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a peripheral device may synchronize a local clock to an access point timing synchronization function clock (TSF_AP) that is maintained by an access point (AP) connected to the peripheral device. The peripheral device may maintain, based at least in part on the local clock, an estimated time-to-play timing synchronization function clock (TSF_est) that is associated with outputting user data. The peripheral device may receive, from the AP, timing synchronization information that is based at least in part on a comparison between a wireless communication device (WCD) time-to-play timing synchronization function software clock (TSF_soft) and the TSF_est. The peripheral device may output the user data based at least in part on the TSF_est and the timing synchronization information. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for transport of extended personal area network (XPAN) control frames across networks. Some aspects more specifically relate to the transmission of a message within an XPAN, in which a first wireless station (STA) and a second STA are out of range (such as greater than 10 meters apart). For example, the first STA and the second STA may share a Layer 2 (L2) network, a Layer 3 (L3) network, neither, or both. The first STA may generate the message, which may include an XPAN control frame and at least one network communication header. In some implementations, the at least one network communication header may include an L3 header and an L2 header. The first STA may transmit the message to the second STA via one or more access points (APs).

Abstract: Methods and devices for scheduling processing tasks in a computing device configured with a group of low-power processor cores and at least one high-performance processor core may include identifying multiple application streams related to communication with a wireless local area network (WLAN), computing a total WLAN throughput requirement for the application streams, and determining whether the total WLAN throughput requirement is less than a first threshold value. The first threshold value may be based on power characteristics of the low-power processor cores. In response to determining that the total WLAN throughput requirement is less than the first threshold value, the computing device may schedule all processing tasks for the multiple application streams on one of the low-power processor cores.
