CHANNEL SOUNDING LOCALIZATION WITH MULTIPLE VEHICLE ANCHORS

Abstract

A method for Channel Sounding (CS) localization with multiple vehicle anchors includes performing a CS procedure to generate a first remote data at a digital key and a first local data at a first one of a plurality of anchors. A first distance between the digital key and the first anchor is determined from the first remote data received from the digital key and the first local data. A connection handover from the first anchor to a second one of a plurality of anchors is performed. The CS procedure is performed to generate a second remote data at the digital key and a second local data at the second anchor. A second distance between the digital key and the second anchor is determined from the second remote data received from the digital key and the second local data. A location of the digital key is trilaterated using at least the first distance and the second distance.
