Abstract
A frequency-efficient antenna operation method is provided in a multiuser beamforming system. The method includes determining channel correlations and channel gain differences between channels using channel information received from multiple terminals, classifying the multiple terminals into at least one or more clusters using the channel correlations and channel gain differences, selecting a beamforming vector for each of the one or more clusters using the channel information of at least one or more terminals in the one or more clusters, allocating power to the terminals in each of the one or more clusters, and forming a beam based on the allocated power and the selected beamforming vector. According to the method, interference due to sharing space resources may be reduced and more efficient data communication may be achieved.
