Abstract: Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.

Abstract: This disclosure describes systems, methods, and devices related to generating a wake up receiver (WUR) transmit waveform. A device may determine one or more symbols bit sequence of a wake up receiver (WUR) frame to be sent to a first station device capable of decoding the bit sequence. The device may determine a first symbol of the one or more symbols, wherein the first symbol is associated with an ON state. The device may determine a second symbol of the one or more symbols, wherein the second symbol is associated with the ON state. The device may generate a first on-off keying (OOK) waveform associated with the first symbol. The device may generate a second OOK waveform associated with the second symbol, wherein the second OOK waveform is different from the first OOK waveform. The device may cause to send the WUR frame to the first station device based on the first OOK waveform and the second OOK waveform.

Abstract: A wireless communication system and method. The system includes processing circuitry, and a transceiver coupled to the processing circuitry. The processing circuitry includes logic to generate a wake-up packet addressed to another wireless communication system and including a legacy preamble portion and a wake-up portion, the legacy preamble portion modulated according to a first modulation rate. The wake-up portion is modulated according to a second modulation rate lower than the first modulation rate and includes information to wake-up the other wireless communication system. The transceiver system is to transmit the legacy preamble using a first transmit power level, and to transmit the wake-up portion using a second transmit power level higher than the first transmit power level by a predetermined amount such that an average received power of the wake-up portion is equal to an average received power of the legacy portion at the third-party station.

Abstract: Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

Abstract: Logic to manage synch frame transmissions in a synch network via helper stations (STAs) synched to the network. Logic may coordinate actions of helper STAs via a transmission window (TW) provided by a master clock STA. Logic may distribute synch frame transmissions within a TW via synch logic in the helper STAs. Logic in helper STAs of a synch network may determine discovery periods in which to transmit synch frames between synch frame transmissions by the master clock STA. Logic in helper STAs to determine a discovery period in which to transmit synch frames to share workload with the master clock STA and to extend the coverage area of the synch network. Logic of the master clock STA may establish a fixed TW based upon the number of helper STAs and a time constraint for discovering the synch network. Or logic of the master clock STA may establish a dynamic TW in which the master clock STA can adjust the TW based upon a number of synch frame transmissions during a TW.
