    Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

    Abstract: Logic may comprise a single phase tracking implementation for all bandwidths of operation and the logic may adaptively change pre-defined and stored track parameters if the receiving packet is 1 MHz bandwidth. Logic may detect a packet and long training fields before performing a 1 MHz classification. Logic may auto-detect 1 MHz bandwidth transmissions by a property of the long training field sequences. Logic may auto-detect 1 MHz bandwidth transmissions by detecting a Binary Phase Shift Keying (BPSK) modulated first signal field symbol rather than the Quadrature Binary Phase Shift Keying (QBPSK) associated with the 2 MHz or greater bandwidth transmissions. Logic may perform an algorithm to determine an estimated phase correction value for a given orthogonal frequency division multiplexing symbol and several embodiments integrate this value with an intercept multiplier that may be 0.2 for 1 MHz transmissions and, e.g., 0.5 for 2 MHz or greater bandwidth communication.

    Abstract: This disclosure describes systems, methods, and devices related to wake up receiver (WUR) frequency division multiple access (FDMA) transmission. A device may cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices. The device may determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices. The device may determine to apply padding to the first wake-up frame based on a field included in a header of the first wake-up frame. The device may cause to send the first wake-up frame to a first station device of the one or more station devices.

    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: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.
