ABSTRACT:
Wireless communication techniques for cellular deployment of wireless communication systems with transmitters in each cell to have partially overlapped transmission patterns between two adjacent transmitters. Implementations of the described techniques can provide transmit diversity with intentional partial beam pattern overlays to improve cell sectorization or frequency re-use factor, at the same time, reduce intra-cell and inter-cell interference. Various modulations may be used in the described systems, including FDMA, TDMA, and OFDMA modulation schemes.
