Methods, architectures, apparatuses, and systems for sensing target detection

Abstract

A method is performed by a wireless transmit/receive unit (WTRU) for detecting a target object (TO). The method includes receiving configuration information that includes a TO path profile, an environmental object (EO) path profile, and a confidence indicator. The WTRU receives reference signals and performs path measurements to identify candidate object paths. Based on the TO path profile, EO path profile, and confidence indicator, the WTRU determines a TO path and at least one false alarm path. The WTRU then transmits information about the path measurements associated with the TO path or the false alarm path to a wireless network. The method includes using thresholds for confidence indicators and false alarm probabilities, and may involve downlink positioning reference signal (DL-PRS) configurations. Path measurements can include various metrics such as reference signal received power, delay, angle of arrival, and doppler shift.
