Abstract

It is presented a method for determining a position of a wireless device, the method being performed in a network node connected to a plurality of remote radio heads via a combiner. The method comprises the steps of: adjusting a weighting of an uplink signal for at least one of the remote radio heads; measuring a signal quality of a combined uplink signal received via the combiner; repeating the steps of adjusting and measuring until an exit condition is true; and determining a position of the wireless device based on how the measured signal quality differs for adjustments of weighting of the uplink signal for different remote radio heads.
