Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may perform a clock tracking procedure that comprises: transmitting, to an access point (AP), an extended personal area network (XPAN) synchronization message pair that is addressed to a peripheral device associated with the WCD, and receiving, from the AP, an XPAN synchronization response message pair that is associated with the XPAN synchronization message pair. The WCD may transmit, to the AP, user data that is addressed to the peripheral device at a time that is based at least in part on an estimated awake window, the estimated awake window being based at least in part on the XPAN synchronization response message pair. Numerous other aspects are described.

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.
