摘要： Systems, devices, and methods for mitigating collisions between wireless transmissions operating at different bandwidths are disclosed. As such, a wireless device operating at a predefined bandwidth includes a transceiver that receives a signal across a wireless channel, a filter that generates a band-limited filtered signal at the predefined bandwidth of the wireless device, a correlating mechanism that correlates the band-limited filtered signal with a delayed, conjugated version of the band-limited filtered signal, logic that performs a moving average of the correlated filtered signals to determine correlation peaks, and logic configured to compare the correlation peaks with a predetermined threshold. With this configuration, if the correlation peaks are greater than the predetermined threshold, the received signal is determined to operate at a wider bandwidth than the predefined bandwidth of the wireless device, and the wireless device defers accessing the wireless channel to transmit until a predetermined time interval.

摘要： 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.

The device-to-device connection establishment technique may include a transmission of a discovery request to available devices, a transmission of a response from available devices including authentication data, and a verification of the authentication data. The authentication data may include previously stored image data associated with a device or human user associated with a device. In further examples, image processing and image recognition techniques may be used to verify a particular device or human user associated with a device.

摘要： 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 two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.

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.
