ABSTRACT:
The present invention provides a method and an apparatus for controlling a radio frequency transmission, over a downlink to at least one mobile station user among a plurality of mobile station users, from a plurality of antennas associated with a base station in a wireless communication system. The method includes tracking a channel corresponding to the mobile station user of the plurality of mobile station users based on feedback information indicative of a state of the channel therefrom. The method further includes scheduling, for the at least one mobile station user, a directional transmission based on the tracked channels of the plurality of mobile station users.
