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.

Abstract: Pilot logic may determine based upon channel and phase information how to process pilot tones that shift locations every N symbols in an orthogonal frequency division multiplexing (OFDM) packet transmission. Pilot logic may determine a signal-to-noise ratio (SNR) for the channel to determine how to process the shifting pilot tones. Pilot logic may also determine channel and phase information updates such as channel state information and phase correction information from pilot tones. In situations of high SNR, logic may use channel estimates and phase rotations that are obtained from locations of the pilot tones for phase tracking and updating the equalizer. In situations of low SNR, logic may use the phase rotations for phase tracking and not update the equalizer during the OFDM transmission. Logic may also determine the presence or absence of a Doppler effect on the transmission and transmit a selection for N to an access point in response.

Abstract: Logic may determine a first frame comprising a hopping pattern value and a target hopping time (THT). The hopping pattern may indicate a pattern of channels to which to hop. Logic may determine a clear-to-send (CTS) frame comprising a duration value indicative of a duration of a data transmission. Logic may transmit the first frame on at least a primary channel of the channels. Logic may transmit the CTS frame prior to transmitting the data transmission on the one or more channels in accordance with the hopping pattern, each channel having a bandwidth of at least 450 megahertz and being within in a 6 gigahertz to 10 gigahertz frequency band. Logic may receive a frame on at least a primary channel of the channels. Logic may receive CTS frames at the THT in accordance with the hopping pattern.
