Abstract
Systems, methods, and devices for wireless communication that support backscatter-based positioning. A method of wireless communication includes receiving a tag device indicator that indicates a tag capability of a tag device. The method also includes generating a tag configuration associated with transmission of a backscatter signal based on a positioning reference signal (PRS). The tag configuration indicates a frequency shifting parameter based on a frequency shifting capability of a tag device, a phase scrambling parameter based on a phase scrambling capability of the tag device, or a combination thereof. The method further includes transmitting the tag configuration.
