Abstract

In a CDMA cellular communication network, packet data may be broadcast at a discontinuous rate using a packet scheduler 7 which utilises available communication resources in each cell more efficiently than for continuous transmission. To maintain quality of service requirements, each packet scheduler is associated a power bin (9,10,11) which represents the total power available for transmission and reception in the cell. The maximum power level for each power bin may be adjusted in dependence of the quality of service experienced in each cell. A cell experiencing high levels of traffic may have its power bin increased to maintain acceptable carrier to interference levels at mobile stations 4,5, this is achieved by reducing the power bins of neighbouring cells which reduces intercell interference. Cell power levels are calculated using a genetic algorithm.
