Classification: CPC H  G | IPC G  H

Claim 7:
8. A first wireless device for bi-static radio-based object location detection, the first wireless device comprising:
a transceiver;
a memory; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
obtain a location of a second wireless device;
obtain a time-of-flight (ToF) and an angle of arrival (AoA) of a wireless wide-area network (WWAN) reference signal transmitted by a transmitting device, wherein the TOF and the AoA are obtained from measurements of the WWAN reference signal at a receiving device after the WWAN reference signal is reflected by an object, further wherein obtaining the AoA of the WWAN reference signal includes configuring the one or more processors to obtain a differential AoA (DAoA) indicative of an angle between a reflected path of the WWAN reference signal and a direct path between the first wireless device and the second wireless device; and
determine a location of the object based on the location of the second wireless device, the ToF, and the AoA, wherein:
the first wireless device comprises the transmitting device and the second wireless device comprises the receiving device, or
the first wireless device comprises the receiving device and the second wireless device comprises the transmitting device.
