1. A method of acquiring a beamforming pattern in a wireless communication system, the method comprising:

  • receiving a first plurality of signals having different transceiver sector patterns;

    measuring first indicators of link quality corresponding to the first plurality of signals;

    selecting at least one transceiver sector pattern based on the first indicators of link quality;

    transmitting a first selection signal comprising data indicative of the selected at least one transceiver sector pattern;

    receiving a second plurality of signals having different transceiver beam patterns, each transceiver beam pattern associated with the selected at least one transceiver sector pattern;

    measuring second indicators of link quality corresponding to the second plurality of signals; and

    selecting at least one transceiver beam pattern based on the second indicators of link quality,wherein the selected at least one transceiver sector pattern is associated with a sector codebook and the selected at least one transceiver beam pattern is associated with a beam codebook.
