<P>PROBLEM TO BE SOLVED: To improve communications efficiency by combining an optimal MIMO transmission control techniques while taking into account kinds and states of physical channels. Ž<P>SOLUTION: A method of controlling downlink transmission from a base station having multiple antennas to a mobile station having multiple antennas includes the steps of: applying open loop-type MIMO diversity to a common control channels, an MBMS channel, and an L1/L2 control channel; and applying closed loop-type MIMO multiplexing and/or MIMO diversity to a shared data channel.
