摘要：
The present invention relates to a node (1) in a wireless communication system, the node (1) comprising at least one antenna (2) which comprises an even number (A) of antenna ports (3, 4, 5, 6), at least four, where each antenna port (3, 4, 5, 6) is associated with a corresponding polarization (P1, P2), beam-width and phase center. The antenna ports (3, 4, 5, 6) are connected to a reconfiguration network (7) which is arranged for pair-wise linear combination of antenna ports (3, 4, 5, 6) of mutually orthogonal polarizations to a number (B) of virtual antenna ports (8, 9), which number (B) is equal to half the number (A) of antenna ports (3, 4, 5, 6). The virtual antenna ports (8, 9) correspond to virtual antennas and are connected to corresponding radio branches (10, 11). The present invention also relates to a corresponding method.
