Abstract

A method (200) for determining statistics for the Direction of Departure between a UE and a base station. The method (200) comprises receiving measurement reports from the UE on the strength of signals in the UE from one or more of the cells served by the base station and for one pair of cells served by the base station determining (220) whether or not the UE was limited in measuring the strength of the signals and if the UE was limited determining (230) said statistics using the signal strengths from the cells in the pair the cells antenna gain towards the UE and the maximum difference between the signal strengths from the cells in the pair and if the UE was not limited determining (225) said statistics using the signal strengths from the cells in the pair and differences in the cells antenna gain towards the UE.
