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. If a base station is experiencing a higher level of traffic than its neighbours, the power bin for that cell may be increased with quality of service requirements being maintained by decreasing the power bins of neighbouring cells. Reducing the maximum transmission value for an under utilized base station, decreases intercell interference in neighbouring cells. This means that more packets can be scheduled to an overloaded cell (1) without increasing transmission power, whilst maintaining a target signal to interference ratio at a receiver. (4,5).
