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: 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: A wireless communication system, system and method. A wireless communication device comprises a memory, and processing circuitry including logic. The processing circuitry is to decode a wake-up payload, when a main radio associated with the device is in a sleep state, using an operational cyclic prefix length for the packet. The operational cyclic prefix length may be one of a fixed cyclic prefix length, a cyclic prefix length used for a last packet transmission by the main radio, and a selected cyclic prefix length determined by the processing circuitry. The processing circuitry may further cause a wake-up of the main radio based on the wake-up payload to allow the main radio to process a subsequent packet after waking up.

Abstract: Embodiments of a wireless station and method for communicating in a Wi-Fi network in accordance with coexistence techniques are described. The station (STA) can include memory and processing circuitry. The processing circuitry is configured to decode a packet received from a second STA, the packet including an information element (IE) indicating the second STA is one of a hybrid class device or a narrowband (NB) class device. When the IE indicates that the second STA is a hybrid class STA, a hybrid packet is generated for transmission to the second STA. The hybrid packet includes a legacy preamble followed by a narrowband (NB) preamble and a NB payload. When the IE indicates that the second STA is a NB class STA, a NB packet is generated for transmission to the second STA. The NB packet including the NB preamble and the NB payload, and is generated without the legacy preamble.

Abstract: Techniques for presenting communication by two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for bandwidth adaptation using echo cancellation. Even more specifically, a narrow-bandwidth transmission can be interrupted in favor of a higher-bandwidth transmission upon one or more secondary channels becoming available or going quiet.

Abstract: Logic of an access point may transmit a null data packet for beamforming training and transmit a beamforming report poll to the first station on a user list before receiving a transmission from the first station on the user list. Logic may wait for a timeout period to determine whether the first station on the user list will respond to the null data packet prior to transmitting the beamforming report poll. Logic may receive from the first station an indication that the first station is a slow beamforming report responder. Logic may reorder the user list to position a fast beamforming responder as the first station. And logic of the station may determine that the station is unable to complete and transmit the report so the logic may wait to transmit the beamforming report in response to a subsequent beamforming report poll frame.
