Abstract
Disclosed are techniques for wireless positioning. In an aspect, a network entity, such as a location server, may determine information characterizing a channel associated with a wireless device within a region of interest. The network entity may determine a location of the wireless device within the region of interest based on that information and a set of radio frequency fingerprints (RFFPs), where each RFFP identifies a geographic location within a region of interest and a channel condition at that geographic location within the region of interest, and where each geographic location within the region of interest is represented by a set of RFFPs having different channel conditions due to different states of at least one reconfigurable intelligent surface (RIS) within the region of interest.
