Abstract
The present invention provides a method for reducing a wireless positioning error by a target node in a multi-node system. Specifically, the method comprises the steps of: receiving information on the positions of anchor nodes from the anchor nodes, respectively; performing ranging of each of the anchor nodes; and when the target node is in a first state, transmitting information on the position of the target node to neighboring nodes except for each of the anchor nodes. The target node is capable of communicating with at least one of another target node, a target node related to an autonomous driving vehicle, a base station or a network.
