The present invention relates to a transmit device for a wireless communication system (500), the transmit device (100) comprising: at least one logical antenna port (102) configured to provide a broadcast component signal; an antenna array (104) having M number of rows and N number of columns of antenna elements (106a, 106b,..., 106n), wherein each antenna element (106) comprises at least one physical antenna port (108) in one polarization; a processor (1 10) configured to select Q number of columns among the N number of columns, where Q≤ N, determine a phase centre location (PCL) for the logical antenna port (102), wherein the phase centre location (PCL) is arranged in a point on a vertical axis (A) located in the Q number of columns, map the logical antenna port (102) on the physical antenna ports (108a, 108b,..., 8q) of the Q number of columns based on the determined phase centre location (PCL); wherein the antenna array (104) is configured to transmit the broadcast component signal on the mapped physical antenna ports (108a, 108b,..., 108q) of the Q number of columns. Furthermore, the present invention also relates to a corresponding method, a computer program, and a computer program product. |
