摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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 two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.

摘要： 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.

摘要： Wireless devices, methods, and computer readable media are disclosed. A high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master station may include circuitry. The circuitry may be configured to generate one or more resource allocations of a bandwidth for one or more HEW stations. Each resource allocation for a first portion of the bandwidth may be a multiple of a basic resource allocation or the entire first portion of the bandwidth. There may be only one resource allocation for a second portion of the bandwidth that is at least as large as the first portion of the bandwidth. In some embodiments, each resource allocation for the second portion of the bandwidth may be a multiple of the basic resource allocation or the entire second portion of the bandwidth.
