Abstract
Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a first wireless device, such as an energy harvesting device, may receive, from a second wireless device, such as an energy transmitting device, parameters associated with backscattering a positioning signal, the parameters including an identifier associated with the first wireless device and an indication of a time offset associated with transmission of a backscattered positioning signal. The first wireless device may receive the positioning signal based on the identifier and transmit the backscattered positioning signal based on applying a backscattering function to the positioning signal in accordance with the offset. The second wireless device may calculate a position of the first wireless device based on a time of reception of the backscattered positioning signal and the time offset.
