Abstract:
1. A method for reducing interference in a wireless communication system, the method comprising: generating a plurality of tiles for transmission, each tile including an upper half-tile and a lower half-tile, the upper half-tile comprising sub-carriers with frequencies that are higher than the frequencies of the sub-carriers of the lower half-tile; defining a hopping sequence for small messages, wherein the hopping sequence is different from hopping sequences used in neighboring sectors to reduce the possibility of collisions; based on the hopping sequence, inserting a small message into only the upper half-tile of a first tile and inserting pilot information into only the lower half-tile of the first tile; and based on the hopping sequence, inserting the small message into only the lower half-tile of a second tile and inserting pilot information into only the upper half-tile of the second tile.
