Abstract: Techniques and apparatus for determining a transmit power limit based on sensor spatial coverage. A method that may be performed by a wireless communication device includes selecting a beam for transmission of a signal, determining a transmit power limit based at least in part on an overlap between the selected beam and a coverage zone of a sensor, and transmitting the signal via the beam at a transmit power based at least in part on the determined transmit power limit.

Abstract: Systems and methods for detecting a body part like a human hand near a base station or a user equipment are disclosed. A plurality of radar pulses is transmitted from a communication device in succession and the reflected plurality of radar pulses is received sampled and adaptively processed to remove transmit and receive antenna mutual coupling and clutter from stationary objects near the body part. In one aspect the adaptive processing is accomplished with a single tap adaptive filter. The processed signal may be used to determine if there is a human body part near the communication device allowing the device to determine whether it is safe for the device to transmit a millimeter wave communication signal.

Abstract: Aspects of the present disclosure provide a simplified solution for proximity detection of an object in a wireless communication that does not require complex hardware to maintain mutual coupling reference signal. Specifically, in accordance with aspects of the present disclosure, the received signal that may include the mutual coupling signal and target signal may be multiplied by itself to extract the delay information associated with the target signal. The techniques outlined here may provide a greater robustness to variations of mutual coupling induced by phone covers, for example, being added by the user.

Abstract: Certain aspects of the present disclosure provide techniques for operating a wireless device pursuant to radio frequency (RF) exposure compliance. A method that may be performed by a wireless device includes switching sensing circuitry to a first mode in response to one or more first criteria being satisfied; switching the sensing circuitry to a second mode in response to one or more second criteria being satisfied; and transmitting a signal at a transmit power determined based at least in part on a radio frequency (RF) exposure limit, and if the sensing circuitry is operating in the second mode, on one or more measurements associated with the sensing circuitry.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit a frequency-modulated continuous-waveform (FMCW) dual ramp radar signal over a time duration that sweeps from a first frequency to a second frequency and from the second frequency to the first frequency. The wireless device may receive a reflection of the radar signal with a first reflected part that corresponds to the first part of the radar signal and a second reflected part that corresponds to the second part of the radar signal. The wireless device may compare the first reflected part and a time-inverted version of the second reflected part to estimate a noise pattern. The wireless device may perform an action based at least in part on the noise pattern. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to a programmable multi-mode digital-to-analog converter (DAC) for generating a frequency-modulated signal. For example, certain aspects provide a circuit for sweeping a frequency of an output signal. The circuit generally includes a DAC having an input coupled to an input path of the circuit and an output coupled to an output path of the circuit, a first mixer selectively incorporated in the input path coupled to the input of the DAC, and a second mixer selectively incorporated in the output path coupled to the output of the DAC.

Abstract: Aspects presented herein may enable a wireless device (e.g., a joint FMCW radar and communication system) to transmit and/or receive an FMCW signal and an OFDM signal using the same time and frequency resources. In one aspect, a first wireless device receives an indication of a scheduled transmission for an FMCW waveform via a set of time-frequency resources. The first wireless device transmits or receives the FMCW waveform via the set of time-frequency resources based on the indication, where the FMCW waveform is separated from an OFDM waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the FMCW waveform and the OFDM waveform.

Abstract: Some disclosed devices include an inertial sensor system, a proximity sensor system, an antenna system configured to transmit and receive radio signals and a control system. The control system may be configured for receiving inertial sensor data from the inertial sensor system and controlling the proximity sensor system and/or the antenna system based, at least in part, on the inertial sensor data. In some examples, the control system may be configured for controlling the proximity sensor system and/or the antenna system based, at least in part, on whether the inertial sensor data indicates that the device is being held, is being carried or is on a person's body (e.g., is in the person's pocket).

Abstract: In some aspects, a radar device may receive a received signal comprising a reflected frequency modulated continuous wave (FMCW) radar signal and interference. The radar device may identify the reflected FMCW radar signal based at least in part on performing a phase based search procedure to facilitate removing the interference from the received signal. The radar device may perform an action based at least in part on a characteristic of the identified reflected FMCW radar signal. Numerous other aspects are described.
