摘要： Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

摘要： Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, super-blocks, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.

摘要： Logic may implement an orthogonal frequency division multiplexing (OFDM) system operating in the one gigahertz and lower frequency bands. Logic may detect new long training sequences that are differentially orthogonal to each other for a first bandwidth mode of operation such as a one megahertz mode as well as differentially orthogonal to half of the long training sequence for a second bandwidth mode of operation such as a two megahertz or greater mode. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. Logic may implement a new acknowledgement packet comprising a short training sequence and a long training sequence without a signal field and without a payload. And logic may implement bandwidth detection logic to classify a transmission based upon orthogonal properties of the long training sequences.

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 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： Methods, apparatuses, and computer readable media for ultra-low latency out-of-band radios are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to associate with an access point (AP) on a first channel using a first transmit power, encode a physical (PHY) protocol data unit (PPDU) for transmission on a second channel, and configure the STA to transmit the PPDU on the second channel with a second transmit power, wherein a bandwidth of the first channel is less than the bandwidth of the second channel and wherein the first transmit power is greater than the second transmit power. The second channel may be punctured based on overlapping basic service sets (BSS) (OBSSs) signal strengths. The use of the second channel is restricted for communications related to low-latency applications. The transmit power on the second channel is reduced to lower the interference with OBSSs.
