1. One kind in wireless communication system, in the method for controlling radio frequency transmission from multiple antennas relevant to base station to the down link of at least one user of mobile station among multiple user of mobile station, described method comprises:

  • At described base station place, feedback information based on indicating channel state is followed the tracks of the channel corresponding to described at least one user of mobile station, channel tracking comprises that the value of the expression to the channel corresponding with described at least one user of mobile station estimates in real time, provide described feedback information with described base station selected speed, to be supported in the scheduling of the directed downlink transmission from described base station to described at least one user of mobile station on tracked channel;

    AndBased on the tracked channel of described at least one user of mobile station, dispatch directed downlink transmission for described at least one user of mobile station, described scheduling utilizes proportional fair algorithm to carry out.
