Abstract
A method includes determining backscatter frequency offsets assigned to backscatter nodes to be positioned; controlling transmitting, by the first user device, a positioning signal using time-frequency resources found unused by the first user device or allocated by a network node; controlling receiving, by the first user device via sidelink communication, channel estimate information from a plurality of second user devices, wherein a channel estimate information indicates an estimate of a channel between one of the plurality of second user devices and each of the at least some of the backscatter nodes, and wherein the channel estimate information received from each second user device is based on the transmitted positioning signal that is frequency shifted by an assigned backscatter frequency offset and reflected by each of the at least some of the backscatter nodes; and controlling transmitting, by the first user device to the network node, the received channel estimate information.
