Abstract: A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

Abstract: Embodiments of a LP-WUR (low-power wake-up radio) wake-up packet acknowledgement procedure are generally described herein. A first wireless device encodes for transmission of a wake-up packet of a LP-WUR to a second wireless device, the wake-up packet to wake up a WLAN (wireless local area network) radio of the second wireless device. Upon decoding a response frame from the second wireless device received during a predefined time period: the first wireless device encodes for transmission of a data packet to the WLAN radio of the second wireless device. Upon failing to receive the response frame from the second wireless device during the predefined time period: the first wireless device encodes for retransmission of the wake-up packet to the second wireless device.

Abstract: Embodiments of a low-power wake-up radio (LP-WUR) are generally described herein. In some embodiments, a wireless device is set to a first state or a second state, wherein in the first state the wireless device is configured to receive wake-up (WU) packets, and wherein in the second state the wireless device is configured to not receive WU packets, wherein the wireless device comprises a WLAN radio and a low-power wake-up radio (LP-WUR). In some embodiments, the wireless device is configured to receive a wake-up packet, turn on the WLAN radio and turn off the LP-WUR. In some embodiments, the wireless device is configured to turn off the WLAN radio and turn on the LP-WUR for power conservation. In some embodiments, the wireless device turns off the WLAN radio and turns off the LP-WUR, and can periodically turn on the LP-WUR radio for extreme power saving.
