Abstract: A communication device and a corresponding device operating method include an ultra-wideband (UWB) communication unit enabling UWB communication with at least one external communication device, and a processing unit performing a ranging session between the communication device and the external communication device. The ranging session includes one or more distance measurements based on messages exchanged between the communication device and the external communication device. The messages are exchanged through the UWB communication unit. The device also includes a prioritization unit configured to prioritize the ranging session using a synchronization indicator associated with the ranging session.

Abstract: A method includes transmitting, with a transmitter, a first radar detection frame, and beginning a timer, at least in part based on the transmitting. The method also includes disabling a receiver, at least in part based on the transmitting. The method further includes enabling the receiver to receive a first radar detection response, at least in part based on the timer and a detection duration of a gating window of the receiver. In addition, the method includes receiving the first radar detection response with the receiver, the first radar detection response including a first reflection of a first target. The method additionally includes increasing the detection duration of the gating window, at least in part based on a determination that the first reflection of the first target was detected in the first radar detection response.

Abstract: Embodiments of methods of providing a machine learning (ML) model for detection of radar targets are disclosed that include determining, using ultra-wideband circuitry, range data and location data from a range doppler map corresponding to one or more locations of one or more targets. The method may include determining, using the ML model, estimated target locations based on data from a Doppler range map and iteratively training the ML model based on differences between the estimated target locations and ground truth including a selected one of the location data or the range data.

Abstract: A method is provided for detecting interference in a radar system. The method includes transmitting, by a transmitter of the radar system, a sequence of radar pulses at a regular interval with a rest period following each radar pulse of the sequence of radar pulses. The transmitter is disabled during each rest period. A receiver is enabled to receive reflected radar pulses from a target during the rest period following each radar pulse of the sequence of radar pulses. Some of the radar pulses are selected to be omitted and not transmitted. The receiver is still enabled during the rest periods following the omitted transmission pulses. Any reflected pulses received during the rest periods following the omitted transmission pulses may be an indication of a targeted interference of the radar system. In another embodiment, a radar system is provided.
