ABSTRACT:
A method and apparatus for transmitting data to a plurality of users, each individual user disposed in one of a plurality of cells is disclosed. One embodiment of the method comprises the steps of defining a first set of receivers from at least a portion of the plurality of receivers according to a first desired power level range, defining a first group of receivers from the first set of receivers according to a first spatial isolation constraint, defining a second set of receivers from a remaining plurality of receivers not a member of the first set of receivers according to a second desired power level range, defining a second groups of receivers from the second set according to a second spatial isolation constraint, and assigning a first transmission channel to the first group and a second transmission channel to the second group.
