This disclosure provides systems, methods, and devices for wireless communication that support backscatter-based positioning. In a first aspect, a method of wireless communication includes transmitting a configuration signal that indicates a tag address of a tag device and a modulation scheme for generation of a backscatter signal. The method also includes transmitting a positioning reference signal (PRS) after transmission of the configuration signal. The method further includes receiving, from the tag device, a backscatter signal based on the modulation scheme and the PRS. Other aspects and features are also claimed and described.
