Abstract

A wireless communication system comprising at least one base station in a communication cell, wherein the base station is equipped with at least one array antenna comprising at least two antenna ports which are connected to respective at least two corresponding antenna elements, wherein at least two of the at least two antenna elements have essentially the same polarization. The array antenna is arranged for communication via at least two antenna radiation lobes, each antenna radiation lobe communicating an information stream to at least one user equipment (UE) in the cell, wherein each antenna radiation lobe is individually controllable both in azimuth and elevation, whereby the communication of the information streams is optimized.
