PROBLEM TO BE SOLVED: To improve the transmission efficiency by combining appropriate MIMO transmission control methods, taking into consideration the physical channel types and channel conditions. SOLUTION: In a method for controlling downlink transmission from a base station, having a plurality of antennas to a mobile station having a plurality of antennas, an open-loop MIMO diversity is applied to a common control channel, an MBMS channel, and an L1/L2 control channel, while a closed-loop MIMO multiplex and/or MIMO diversity is applied to a shared data channel.
