Abstract

This document discloses a method for determining spatial conditions between a first radio device and a second radio device, the method comprising: path loss ranging, by the first radio device, the second radio device and computing at least one path loss estimate indicating a first distance between the first radio device and the second radio device; phase ranging, by the first radio device, the second radio device and computing at least one phase ranging value indicating a second distance between the first radio device and the second radio device; computing, based on the at least one path loss estimate and the at least one phase ranging value, at least one parameter describing the spatial conditions between the first radio device and the second radio device.
