Claim Text:
1. Method of selecting antenna segments for transmission and/or reception in a MIMO wireless transmission system using sectorized directional antennas, including: selecting, from an initial set of ranked link antenna patterns, a link antenna pattern having a best average rank, the link antenna patterns corresponding to different selections of activated antenna segments and being ranked in accordance with their average link performance; at predetermined time intervals, successively selecting a subset of link antenna patterns having average ranks within a predetermined distance to the best average rank; determining an average link performance of the link antenna patterns selected during the predetermined time intervals; determining an average rank of the link antenna patterns according to the determined average link performance; selecting antenna segments for transmission and/or reception corresponding to the link antenna pattern having the best average rank; and repeating the process at the next predetermined time interval.
