A method for reducing interference in a wireless system, and a system for performing
the method. The wireless system should include at least two, and preferably four,
beam formers and a plurality of mobile units. The method includes the steps of
transmitting beams B1, B2, B3 and B4 into first, second,
third and fourth beam areas, respectively. At least two sub-areas are defined within
each of the first, second, third and fourth beam areas based upon the degree of
overlap with adjacent beam areas, whereby each of the beam areas includes at least
one overlapping sub-area and at least one non-overlapping sub-area. The method
further includes coding signals of the beams B1, B2, B3 and
B4 for receipt by a particular mobile unit based upon which one of the sub-areas
that the particular mobile unit is located within.
