Abstract
The present invention relates to a method for communicating a signal to a first station from a second station, the stations having antenna array. For communication in bands like 60 GHz, it is advisable to carry out analog beam steering. But it is needed to compute all the beam forming weights in a single message. Then, the invention-proposes that for each signal, in the preamble, a plurality of training symbols are included, wherein during each training symbol repetition, the receiving station adjusts at least one antenna parameter of the plurality of antennas and measuring the combined signal for computing a set of antenna weights to be applied for an analog beam forming on the antenna array for receiving and/or transmitting the data field.
