    Abstract: A receiver for detecting channel occupancy of a radio channel is provided. The receiver includes an oscillation circuit configured to generate an oscillation signal. The oscillation circuit is configured to alternate a frequency of the oscillation signal between at least two different frequency values. Further, the receiver includes a down-conversion circuit configured to generate, based on a received radio frequency signal and the oscillation signal, one of an in-phase component and a quadrature component of a baseband signal. The receiver additionally includes a processing circuit configured to calculate, based on the in-phase component or the quadrature component, a signal power of the radio frequency signal.

    Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of radar detection. For example, an apparatus may include a first detector component to detect energy over a wireless communication channel; a second detector component to detect a signal over the wireless communication channel, and to determine at least a classification of the signal as a radar-type or a non-radar type; a storage component to store radar detection information corresponding to signals detected by the second detector component, the radar detection information including at least the classification of the signal and one or more characteristics of the signal; and a controller to activate the second detector component upon detection of the energy by the first detector component, the controller configured to cause a radar-detection analysis of the radar detection information corresponding to a predefined time period.

    Abstract: Apparatus, computer readable media, and methods are disclosed for sending feedback in a high efficiency service field. An apparatus is disclosed comprising processing circuitry configured to: decode a trigger frame from a second wireless device, wherein the trigger frame indicates a resource allocation for an uplink (UL) multi-user (MU) transmission for the first wireless device. The processing circuitry may be further configured to: determine feedback for a second wireless device based on the resource allocation. The processing circuitry may be further configured to: encode a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to include a high-efficiency (HE) service field comprising the feedback in a physical (PHY) portion of the PPDU. And, the processing circuitry may be further configured to: configure the first wireless device to transmit the PPDU in accordance with the resource allocation to the second wireless device.

    Abstract: Methods and systems for calibrating a transceiver using frequency separation are disclosed. A method configured to calibrate a transceiver that includes connecting an output of a transmitter to an input of a receiver. A receiver local oscillator signal having a receiver local oscillator frequency (fRXLO) is provided to a receiver mixer. A transmitter local oscillator signal having a transmitter local oscillator frequency (fTXLO) to is provided to a transmitter mixer. The receiver local oscillator frequency is separated from the transmitter local oscillator frequency by a nonzero intermediate frequency (fIF). The method includes upconverting a test signal having a baseband frequency (fBB) using the transmitter mixer and downconverting the output signal of the transmitter mixer with the receiver mixer to generate a calibration signal. The transceiver is calibrated based on the calibration signal.
