摘要： A method for designing a soft handoff region in a wireless communications system. An inner region having an outer edge defined by a first radius is selected, wherein a mobile station communicates only with the base station within the inner region and has a selected outage probability at the outer edge of the inner region. Next, a soft handoff region having an outer edge defined by a second radius and an inner edge defined by the first radius is selected, wherein the mobile station within the soft handoff region has the selected outage probability. Actual coverage region having an outer edge defined by a third radius, wherein the third radius is selected to match soft handoff regions of other cells adjacent to the cell.
