1. A method for determining a beamforming vector of an antenna group of a transmitting station in a wireless communication system and a beamforming vector of an antenna group of a receiving station in the wireless communication system, wherein each of the transmitting station and the receiving station comprises a codebook including a plurality of predefined beamforming vectors, the method comprising:

  • performing a test transmission from the transmitting station to the receiving station using a test signal and a beamforming vector pair, the beamforming vector pair including a beamforming vector selected from the codebook of the transmitting station and a beamforming vector selected from the codebook of the receiving station,determining a transmission characteristic of the test transmission at the receiving station,repeating the test transmission and the determination of the transmission characteristic using different beamforming vector pairs, wherein the beamforming vectors in the beamforming vector pair are selected such that each beamforming vector from the codebook of the transmitting station encounters all beamforming vectors from the codebook of the receiving station, anddetermining the beamforming vectors of the transmitting and receiving stations from the beamforming vector pair for which the transmission characteristic has a predefined value.
