Patent ID: 8059743

Claim:
A method for transmitting signals in a wireless communication system, in which signals are transmitted from a transmitting device to a receiving device, at least one of said devices having an antenna generating an antenna beam at different positions, each of said different positions corresponding to a number of different transmission paths from said transmitting device to said receiving device, said signals including a beam steering frame enabling an estimation of a channel quality of a current transmission path, the method comprising: a) transmitting and receiving said signals subsequently via each of the plurality of transmission paths to allow an estimation of channel quality of each of the plurality of transmission paths, b) selecting on a 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 at least one of reduced transmission power or reduced receiver sensitivity for said several transmission paths selected in step b) and d) selecting a small number of transmission paths out of the several transmission paths as candidates for a communication channel on a basis of the channel quality estimated at least one of the reduced transmission power or the reduced receiver sensitivity.
