Generalized reuse partitioning in cellular mobile radio

Reuse partitioning has been proposed as a simple dynamic channel allocation scheme in cellular radio systems. In this method, several overlaid fixed channel plans are used. Mobiles with favorable positions and high signal levels are assigned channels from plans with low reuse distance, whereas mobiles with low signal quality get channels with large cluster sizes. This concept is generalized, and an optimum method for channel assignment given some arbitrary predictor of the signal quality is proposed. Upper and lower performance bounds for the optimum assignment procedure in this class are derived, together with an explicit (suboptimum) assignment procedure. Results show that substantial capacity improvements can be achieved by using the received signal power as predictor
