Abstract

A method of grouping cells of a radio communications network may include defining first and second groups of cells from a plurality of cells that transmit reference signals for positioning measurements. The first and second groups of cells may be defined according to a characteristic of the reference signals transmitted by the respective cells and/or of the respective cells that transmit the reference signals. Reference signals used for positioning measurements from the cells of the first group may be measured at a positioning target device. Reference signals used for positioning measurements from the cells of the second group may be measured at the positioning target device separately in time and/or separately in frequency from measuring the reference signals from the cells (103) of the first group.
