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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit, to one or more peripheral devices, downlink audio packets associated with a left audio channel and a right audio channel during a service period associated with a target wake time (TWT) service interval (SI) periodicity, wherein the TWT SI periodicity is a first integer multiple of a base SI periodicity. The wireless communication device may receive, from the one or more peripheral devices, uplink audio packets associated with a voice back channel (VBC) during a service period associated with a VBC SI periodicity, wherein the VBC SI periodicity is a second integer multiple of the base SI periodicity. Numerous other aspects are described.
