Dynamic channel assignment with reuse partitioning in cellular radio systems

Popular reuse partitioning systems with fixed channel assignment in cellular systems are effective to improve the channel utilization in space. This paper explores an application of the reuse partitioning scheme, in which the dynamic channel assignment technique is introduced. In the proposed strategy, a channel can be simultaneously assigned to both the inner cells and the outer cells by reducing the transmitted power in the inner cells. Also, the rearrangement method is applied to this strategy. The simulation results show that the strategy results in higher channel occupancy. The traffic carried can be increased by 1.5 times as compared with the original fixed channel assignment system.
