A method for pairing a vehicle to a wireless power transfer (WPT) station and determining their relative location using ultra-wideband (UWB) signaling is described. A Master UWB Tag transmits a Ping message and a Master UWB Anchor transmits a Pong message. The Master Tag and Master Anchor use single-sided two-way ranging (SS-TWR) or double-sided two-way ranging (DS-TWR) to determine the distance between them. The Master Tag and the Master Anchor exchange setup parameters to establish communication between the vehicle and the WPT station and determine their relative position. Each UWB tag and each UWB anchor in the WPT station determine a distance between each tag and each anchor. Based on the distances between tags and anchors and data describing the position of each anchor within the WPT station, a relative position of the vehicle and the WPT station is determined.
