Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an access point may start a target wake time (TWT) service period (SP). The access point may receive an end of SP (EOSP) indication from a station. The access point may stop the TWT SP before a scheduled end of the TWT SP based on receiving the EOSP indication. Numerous other aspects are described.

End of service period indication

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.
