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