The embodiment of the invention provides a macro user location determination method, a small cell group and a macro cell. The method is applied to the small cell group. The small cell group comprisesa plurality of small cells which are located in the same heterogeneous network. The macro user location determination method comprises the steps that each small cell obtains user signals of to-be-tested macro users and determines location distance between the to-be-tested macro users and a location of each small cell based on the location of each small cell and the user signals; each small cell sends the location distance between each small cell and the to-be-tested macro users to the macro cell; and each small cell receives to-be-tested macro user locations returned by the macro cell, whereinthe to-be-tested macro user locations are obtained by the macro cell through obtaining of common intersection points of the location distance between the to-be-tested macro users and the each small cell based on the location of each small cell.
