Abstract：In WCDMA system, the radio resource management entity is usually imple mented in the radio network controller. However, transport format in dedicated channels can be changed frame by frame. This fast format change can be seen as a fast part of the ra dio resource control, which is fulfilled by MAC and physical layer in user equipment and node B without any need for L3 signaling. Based on this capability and class-based QoS policy, this paper proposed an algorithm for WCDMA uplink load control. The algorithm consists of iterative rate control and packet scheduling. Simulation results show that the proposed algorithm can achieve fair sharing radio resource and guarantee QoS under multi-service environments.
