In future wireless communications, there will be a mixture of different traffic classes, which have their own load and quality-of-service (QoS) requirements. In this paper, a traffic load and QoS-oriented packet scheduling (TLQS) is proposed for WCDMA communications, which consider the bit error rate (BER), packet loss, delay and traffic load requirements. The BER requirement can be guaranteed by ideal power control, while the packet loss, delay and traffic load are guaranteed by proper packet scheduling. The TLQS is to schedule the transmission of multimedia packets in the way that the TLQS introduces the traffic load and QoS to deciding the priority of the packets, which are more appropriate for designing the scheduler. The simulation results show that the TLQS is effective scheduler for WCDMA system
