Abstract
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 tag configuration message that indicates a first tag configuration and a second tag configuration. The method also includes transmitting a positioning reference signal (PRS). The method also includes receiving, from a first tag device, a first backscatter signal based on the PRS, and receiving, from a second tag device, a second backscatter signal based on the PRS. The method includes transmitting a measurement report that indicates a first round trip time (RTT) of the first tag device, and a second RTT of the second tag device. The first RTT is based on the first tag configuration and the first backscatter signal, and the second RTT is based on the second tag configuration and the second backscatter signal.
