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 B, B, Band Bfor receipt by a particular mobile unit based upon which one of the sub-areas that the particular mobile unit is located within.
