Abstract: Techniques for determining a device location based on measurements from multiple RATs are described. In an aspect, the methods and apparatus include determining, at a first device, one or more round trip time (RTT) measurements based on one or more signals communicated with a second device over a first Radio Access Technology (RAT). Further, in an aspect, the methods and apparatus include determining, at the first device, one or more angle measurements based on one or more signals communicated with the second device over a second RAT. Additionally, the methods and apparatus include determining a location of the first device in relation to the second device based on the one or more RTT measurements and the one or more angle measurements. The one or more angle measurements may include one or more angle of departure (AoD) measurements, one or more angle of arrival (AoA) measurements, or both.
