| 摘要 |
The present invention relates to a method for transmitting signals in a wireless communication system, in which signals are transmitted from a transmitting device ( 1 ) to a receiving device ( 10 ), at least one of said devices ( 1, 10 ) having a narrow beam antenna ( 2, 11 ) which is adapted to be steered to different positions, each of said different positions corresponding to a number of different transmission paths from said transmitting device ( 1 ) to said receiving device ( 10 ), said signals comprising a beam steering frame enabling the estimation of a channel quality of the current transmission path, comprising the steps of a) transmitting and receiving said signals subsequently via each of the plurality of transmission paths thereby allowing an estimation of channel quality of each of the plurality of transmission paths, b) selecting on basis of the estimated channel quality several transmission paths out of the plurality of transmission paths as candidates for a communication channel, c) repeating step a) at least once under different transmission and/or reception conditions for said several transmission paths selected in step b) and d) selecting on basis of the estimated channel quality a small number of transmission paths out of the several transmission paths as candidates for a communication channel.
