Abstract:
1. A method for determining statistics for the Direction of Departure between a User Equipment (UE) in a cellular system and a site for a base station which serves two or more cells in the cellular system and which is equipped with at least one antenna per served cell, the method comprising receiving in the base station measurement reports from the UE which include the strength of signals received in the UE from one or more of the cells which are served by the base station, and for at least one pair of cells served by the base station: determining whether or not the UE was limited with respect to its measurements of the strength of the signals from one of the cells in the pair; if the UE was limited, determining said statistics using the signal strengths from the cells in the pair, the antenna gains of the cells 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 said statistics using the signal strengths from the cells in the pair and differences in the antenna gains of the cells towards the UE.
