  • Patent number: 11412394
    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.

  • Patent number: 11394417
    Abstract: In an aspect, a user equipment (UE) determines a mutual coupling signal associated with a transmit antenna and a receive antenna, determines a mutual coupling difference between the mutual coupling signal and a reference signal, determines a beat signal difference between a current beat signal and a previous beat signal, and determines an amount of micro-motion that is present within a near field. The UE determines whether human tissue is present within the near field based on the mutual coupling difference and the amount of micro-motion. Based on determining that the human tissue is present within the near field, the UE determines an amount of radio frequency exposure associated with the human tissue. Based on determining that the amount of radio frequency exposure exceeds a maximum permissible exposure, the UE reduces the amount of radio frequency exposure associated with the human tissue.

  • Publication number: 20210409129
    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.

  • Patent number: 11194031
    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.

  • Publication number: 20210373127
    Abstract: Methods, systems, computer-readable media, and apparatuses for determining one or more attributes of at least one target based on eigenspace analysis of radar signals are presented. In some embodiments, a subset of eigenvectors to use for forming a signal or noise subspace is identified based on principal component analysis. In some embodiments, the subset of eigenvectors is identified based on estimating the total number of targets using a discrete Fourier transform (DFT) or other spectral analysis technique. In some embodiments, a DFT is used to identify areas of interest in which to perform eigenspace analysis. In some embodiments, a DFT is used to estimate one attribute of a target, and eigenspace analysis is performed to estimate a different attribute of the target, with the results being combined to generate a multi-dimensional representation of a field of view.

  • Patent number: 11122512
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to be positioned in different possible physical configurations and may identify its current physical configuration based on a modem-based sensor. The UE may transmit a signal from a first antenna element and receive an echo of the signal at a second antenna element different than the first antenna element. The UE may then generate an echo signature for the echo of the signal and determine that the UE is in a first physical configuration (e.g., its current physical configuration) from the possible physical configurations by comparing the generated echo signature to a set of echo signatures that correspond to each of the possible physical configurations. Accordingly, based on the determined first physical configuration, the UE may perform an operating system function that corresponds to the first physical configuration.
