A method for determining a position of an object using radio measurement observations in a radio network. An example method comprises the steps of obtaining (1610) information comprising (a) a first angle of arrival parameter and/or a first angle of departure parameter corresponding to a non-primary propagation path of a radio signal transmitted between a first wireless device and a second wireless device, and further comprises one or both of: (b) a delay measurement or a time of arrival measurement on a non-primary propagation path; and (c) a second angle-of-arrival parameter and/or a second angle-of-departure parameter corresponding to the non-primary propagation path, the second angle-of-arrival parameter and the second angle-of-departure parameter corresponding to an end of the non-primary propagation path different from the first angle-of-arrival parameter and the first angle-of-departure parameter. The method further comprises estimating (1620) a location of an object other than the first wireless devic
