Abstract
A method for pilot sequence design in a communications system includes selecting an initial cell in the communications system, and grouping other cells in the communications system relative to the initial cell into one of a neighbor group and a non-neighbor group in accordance with a neighborness measure of each of the other cells to the initial cell. The method also includes designing pilot sequences that are substantially orthogonal to one another for the initial cell and the other cells in the neighbor group, and providing information about the pilot sequences to the initial cell and the other cells in the communications system.
