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.

Abstract: Technologies for providing a cognitive capacity test for autonomous driving include a compute device. The compute device includes circuitry that is configured to display content to a user, prompt a message to the user to turn user's attention to another activity that needs situational awareness, receive a user response, and analyze the user response to determine an accuracy of the user response and a response time, wherein the accuracy and response time are indicative of a cognitive capacity of the user to assume control of an autonomous vehicle when the autonomous vehicle encounters a situation that the vehicle is unable to navigate.

Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

A device may include a wake-up receiver (WURx) and a primary connectivity radio. The device may determine a wake-up radio (WUR) discovery subchannel for WUR advertisement. The WUR discovery subchannel may be associated with a channel of a frequency band. The device may generate a WUR discovery frame comprising a WUR advertisement. The device may transmit, by the WURx, the WUR discovery frame to a second device using the WUR discovery subchannel. The device may identify a response from the second device indicating an acknowledgment of the WUR discovery frame.

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.
