A Base Transceiver Station, BTS (110) and a method (1300) therein, for wireless communication with a User Equipment, UE (120) in a wireless communication system (100). The BTS (110) comprises a Multiple Input Multiple Output, MIMO, antenna array (200) configured for beamforming and MIMO transmission. The BTS (110) further comprises a processing circuit (1420), configured for supporting same or separate downlink precoding for control plane and user plane by modifying phase excitation of the MIMO antenna array (200) and causing a transceiver (220) to create an antenna beam by providing different phase for each antenna element (210) of the MIMO antenna array (200); and a transceiver (220), configured for transmitting a signal in the antenna beam via the MIMO antenna array (200), to be received by the UE (120). |
