Resource allocation in multi-cell CDMA communication systems

In a multimedia code division multiple access (CDMA) system, the network performance depends on the success and efficiency in allocating system resources. The system resources in terms of bandwidth and power should be efficiently distributed to each mobile to guarantee its quality of service (QoS) requirements. In this paper, we propose a received power limited (RPL) power assignment, so that the fair packet loss sharing (FPLS) scheduling can be implemented in the multi-cell resource allocation. The basic idea of FPLS is to schedule the transmission of multimedia packets in such a way that all the users have a fair share of packet loss according to their QoS requirements, which maximizes the number of the served users under the QoS constraints. The RPL minimizes the received power for each packet. With known path loss, it in turn minimizes the transmitted power as well. The intercell interference caused by the scheduled packets is also limited by the scheduling to increase the system capacity.
