Abstract

A method, apparatus, and system are provided for facilitating positioning based on signal correlation function characteristic feedback. In an embodiment, the method may involve steps performed by a network node in communication with a wireless communication device (WCD) and a plurality of base stations. The network node receives, from the WCD, location information including position reference signal (PRS) correlation function characteristics of a cross-correlation between a received downlink signal and a transmitted PRS for each base station from the plurality of base stations. The network node determines a position of the WCD using the PRS correlation function characteristics. The WCD may initiate the transmission of the PRS correlation function characteristics on its own, or in response to a request to do so from the network node.
