Self-organized reuse partitioning, a dynamic channel assignment method in cellular system

Reuse partitioning is an effective concept for spectrum efficiency in cellular systems. A dynamic channel assignment (DCA) method named SORP is proposed, where the reuse partitioning is self-organized. In this method, each base station has a table, where average power for each channel used so far in its cell and the surrounding cells is stored. When a call arrives, the base station measures the output power of the calling mobile station and selects a channel which shows the average power closest to the measured power. The channel is used if available; otherwise, the second closest candidate is tried. Performance is compared between the proposed method, the conventional autonomous reuse partitioning (ARP), and random DCA. For traffic capacity, SORP and ARP show almost the same performance, which is much superior to that of random DCA
