Position estimation method, wireless communication apparatus and wireless communication system

Abstract

There is a position estimation method executed by a radio communication system including a radio communication device and another radio communication device, and the position estimation method includes a radio step of performing radio communication between the radio communication device and the other radio communication device using a directional beam, a relative position estimation step of estimating a relative position of the other radio communication device with respect to the radio communication device based on a direction of the directional beam in which a reception power of the directional beam is maximum in the other radio communication device and a distance corresponding to a round-trip-time of a radio signal between the radio communication device and the other radio communication device, and an absolute position estimation step of estimating the absolute position of the other radio communication device based on the absolute position of the radio communication device and the relative position of the other radio communication device.
