The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.

Abstract: This disclosure provides methods, components, devices and systems for service period based coordinated spatial reuse. Some aspects relate to long term signaling to reduce the amount of signaling while achieving the gain associated with coordinated spatial reuse as compared to distributed spatial reuse. A first wireless device associated with a first basic service set (BSS) may transmit a beacon indicating a set of service periods designated for spatial reuse and an interference threshold. A second wireless device associated with a second BSS may receive the beacon and may communicate with one or more other wireless devices associated with the second BSS during the set of service periods designated for spatial reuse in accordance with the indicated interference threshold. Accordingly, the wireless devices in the second BSS may communicate at a power level that causes an acceptable level of interference at the first BSS.
