Abstract: An electronic device may include wireless circuitry that conveys data with a base station according to a communication standard and that detects range to an external object using a first antenna that transmits a waveform compliant with the standard. The waveform may be a Sounding Reference Signal (SRS) waveform, a transmit data waveform, or another waveform. A second antenna may receive a reflected signal that includes the transmitted waveform. The communications circuitry may perform element-wise division on symbols of a selected subcarrier in the reflected signal using corresponding phases and magnitudes of a set of complex OFDM symbols used to generate the transmitted waveform. Peak detection may be performed to detect the range. Using standard-compliant transmit waveforms to also perform spatial ranging may allow the communications circuitry to avoid dedicated radar circuitry while also minimizing impact to the transfer of the data.

Abstract: Embodiments are disclosed for joint communication and sensing (JCAS) applications with user equipment (UE) including collision alert detection, user vital signs detection, active autofocus in low-light conditions for camera applications and infrared spectroscopy to detect and identify components of a sample of material. Also disclosed is the use of an apodization range-velocity map to improve detection of targets.
