Abstract
The invention provides frequency reuse techniques to enable fractional frequency reuse to be achieved for various cellular radio deployment grids, even for high order modulation such as 16 QAM and 64 QAM by the use of controlled and coordinated notched antenna patterns. The technique allows all frequencies to be used in all cells, thus maximizing system capacity while minimizing and controlling adjacent cell interference by the use of notched antenna patterns.
