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: This disclosure describes systems, methods, and devices related to service set compression. A device may determine a wake-up frame comprising one or more fields, wherein the one or more fields indicate an action to be taken on a receiving device. The device may determine an identifier to be indicated in the wake-up frame. The device may determine a size of the identifier. The device may cause to compress the identifier forming a compressed output, wherein the identifier is compressed by applying a cyclic redundancy code (CRC) computation. The device may identify a portion of the compressed output. The device may cause to send the wake-up frame to a receiving device, wherein the wake-up frame comprises the portion of the compressed output based on the size of the identifier.

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 wake up receiver (WUR) frequency division multiple access (FDMA) transmission. A device may cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices. The device may determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices. The device may determine to apply padding to the first wake-up frame based on a field included in a header of the first wake-up frame. The device may cause to send the first wake-up frame to a first station device of the one or more station devices.

Abstract: Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as an on-off keying (OOK) signal. Logic may generate and receive a wake-up preamble that signals a high data transmission rate with respect to data rates defined for WUR packet transmissions. Logic may generate or receive a preamble that signals a rate of transmission of the WUR packet as 250 kilobits per second. Logic may transmit or receive bits of the wake-up preamble as two microsecond orthogonal frequency-division multiplexing (OFDM) based pulses, wherein each two microsecond OFDM based pulse is based on a 32-point Fast Fourier Transform (FFT) in a 20 Megahertz (MHz) bandwidth, with a subcarrier spacing of 625 Kilohertz (KHz) to produce six subcarriers in a four MHz bandwidth.
