ABSTRACT:
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, B3and B4into 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, B3and B4for receipt by a particular mobile unit based upon which one of the sub-areas that the particular mobile unit is located within.
