    摘要： Some new low power architecture devices may, e.g., be associated with in a new device category in the IEEE 802.11ah Standard for devices with low power architecture. Some new low power architecture devices may only to support a subset of modulation and coding schemes (MCSs). Some new low power architecture devices negotiate the use of the subset of MCSs with an access point. Further new low power architecture devices address power consumption through modifications to the architecture of the new low power device. For instance, many new low power architecture devices remove, modify or bypass portions of the front-end transmitter circuitry and/or the front-end receiver circuitry such as a power amplifier, a low noise amplifier, predistortion circuitry, digital-to-analog and analog-to-digital converter resolutions, and stages of filtering.

    摘要： Logic may calculate predicted phase rotations based upon more than one previously determined phase rotation. Logic may access memory to store and retrieve previously determined phase rotations to calculate predicted phase rotations. Logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the direct current (DC) tone or the band edge (or guard) tones and replace the missing phase rotations with predicted phase rotations. Logic may skip phase tracking from pilot tones that have traveled close to the DC tone or the edge tones or that experience channel fading, which may result in a predicted phase rotation being more accurate than a phase rotation determined by processing the corresponding pilot tone.

    摘要： 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.

    摘要： Logic may generate a wake-up radio packet, wherein the wake-up radio packet comprises an on-off keying (OOK) signal, a sequence of a preamble of the wake-up radio packet to indicate a rate of transmission of one or more OOK orthogonal frequency-division multiplexing (OFDM) symbols of a medium access control (MAC) frame of the wake-up radio packet, wherein a duration of transmission of the preamble is 128 microseconds for a low data rate and a duration of transmission of the preamble is 64 microseconds for a low data rate. Logic may communicate the wake-up radio packet to a physical layer device to transmit OFDM symbols of an IEEE 802.11 preamble on a channel followed by OOK OFDM symbols of the wake-up radio packet on a sub-band of the channel. And logic may generate at least a second wake-up radio packet to transmit on a contiguous channel bandwidth with OOK OFDM symbols.

    摘要： 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.

    摘要： Wireless devices, methods, and computer-readable media for transmitting and receiving high-efficiency signal fields. An access point (AP) may include circuitry configured to determine a high-efficiency signal (HE-SIG) field for each of a plurality of sub-channels, wherein each HE-SIG field includes a common part and a sub-channel specific part. The circuitry may be further configured to transmit, in accordance with orthogonal frequency division multiple access (OFDMA), on each of the plurality of sub-channels, a corresponding HE-SIG field as a preamble to a physical layer convergence protocol (PLCP) protocol data unit (PPDU), wherein the sub-channel specific part of the corresponding HE-SIG field includes a resource map field that enables a HEW device to determine which portion of the PPDU to demodulate, and wherein the common portion includes information of a format of the PPDU. A HEW device may include circuitry configured to demodulate a PPDU based on a HE-SIG field.
