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: An apparatus is disclosed for jammer detection. In example aspects, the apparatus includes a wireless transceiver configured to be connected to multiple antennas. The wireless transceiver is configured to transmit a radar transmit signal using a first antenna of the multiple antennas. The wireless transceiver is also configured to receive a radar receive signal via a second antenna of the multiple antennas, with the radar receive signal associated with the radar transmit signal and comprising a jamming signal component. The wireless transceiver is additionally configured to adjust at least one transmission parameter based on a detected presence of the jamming signal component. The wireless transceiver is further configured to transmit an uplink signal based on the adjusted at least one transmission parameter.

Abstract: Aspects of the disclosure relate to classifying a target object. An electronic device may transmit a detection signal and receive a reflection signal reflected from the target object. The electronic device then determines, based on one or more features of the reflection signal, a category of the target object and adjusts at least one transmission parameter based on the category. The electronic device then transmits an adjust signal using the transmission parameter. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for radar management based on interference detected over an air interface. A method that may be performed by a base station (BS) or a user equipment (UE) includes measuring received power at each of a plurality of receive-beams. The method may also include determining whether the measured power received at one or more of the plurality of receive-beams satisfies a threshold condition. If the measured power received at the one or more of the plurality of receive-beams satisfies the threshold condition, the method may also include selecting a directional transmit beam based on a direction of one of the one or more of the plurality of receive-beams that satisfy the threshold condition, and transmitting a radar waveform over the directional transmit beam.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to address maximum permissible exposure (MPE) proximity sensor failure. A mobile device may include a maximum permissible exposure (MPE) sensor control unit to actively monitor signals associated with proper operation of the MPE proximity sensors. Upon detecting an anomaly in any of these signals, such as a value drop below a given threshold, an MPE sensor control Unit will inform an AP (application processor, or other processor or controller) which in turn trigger display of a warning message on the display of the mobile device or the issuance of other warnings such an audible or tactile alert to inform the end user about the maximum permissible exposure (MPE) proximity sensor malfunction and/or notify the end use of a condition resulting in deactivation of the 5G new radio transceiver.
