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: Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for object detection and three-dimensional reconstruction of objects using coordinated beam scanning. The disclosed techniques teach coordinated beam scanning that can be used for both detecting proximity to personnel in addition to detecting objects for three-dimensional object reconstructions. The techniques form one or more millimeter wave beam that can be electronically steered by adjusting the phase of the various antenna elements. The techniques can include saving the plurality of grid points for which the object is detected to a memory for detecting a range to the object for Maximum Permitted Exposure (MPE) limit monitoring and three-dimensional object reconstruction.

Abstract: Certain aspects provide a method for object detection. The method generally includes: transmitting, via a first antenna, a transmit signal generated via a first transmit chain, the transmit signal being generated based on a mixer output signal; receiving a first receive signal via a first receive chain coupled to a second antenna, the first receive signal being associated with the transmit signal; generating, via a first phase shifter, a first phase-shifted signal based on an adjustment signal received via a signal path coupled to the first transmit chain, the adjustment signal being generated based on the mixer output signal; combining the first phase-shifted signal and the first receive signal to generated a combined receive signal, wherein a phase-shift setting of the first phase shifter is controlled based on at least one of a mutual coupling component or a phase noise of the combined receive signal.

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.
