Abstract

The present invention relates to a method and system for transmitting a transmission signal from an antenna array ( 19 ) to a receiving means ( 20 ) of a wireless communication system, wherein a signal quality measurement is performed at the receiving means ( 20 ) for predetermined antennas or beams of said antenna array ( 19 ). Based on a feedback information derived from the signal quality measurement, at least two of the predetermined antennas or beams of the antenna array ( 19 ) are selected. The selected antennas or beams are used for transmitting said transmission signal according to a transmit diversity or beamforming scheme. Thus, spectral efficiency and diversity gain can be enhanced by using only selected ones of the predetermined antennas or beams.
