Method for estimating positions of devices in wireless access systems supporting communication between devices, and apparatus for supporting same

摘要

The present invention relates to a method for estimating the positions of devices in direct communication with each other, to a method for estimating the structure of a network, and to apparatuses for supporting the methods. According to one embodiment of the present invention, the method for estimating the positions of devices in a wireless access system which supports direct D2D communication between the devices includes the steps of: obtaining information on distance estimation to an adjacent D2D device (for example, a second D2D device) by a D2D device having two reference points (for example, a first D2D device); and estimating the position of the D2D device by using the information on distance estimation and the position information on the two reference points, at which time the information on distance estimation can be obtained through direct D2D communication between the D2D device and the adjacent D2D device.

1. A method for estimating positions of devices in a wireless access system which supports D2D (Device to Device) direct communication, the method comprising:
acquiring two candidate positions of the D2D device from two reference points; acquiring distance estimation information regarding a distance between the D2D device and a neighboring D2D device through D2D direct communication; applying a weight value that corresponds to the D2D direct communication to the distance estimation information; and performing position estimation of the D2D device by selecting one of the two candidate positions using the distance estimation information to which the weight value is applied.
