In W-CDMA uplink, immediate accommodation of high data rate packet causes power control error and makes active users' signal quality deteriorate in the beginning of a frame. To avoid the deterioration, we propose a new radio resource management (RRM), which accommodates high data rate traffic gradually in several frames. The proposed RRM reduces the signal quality deterioration in the beginning of a frame. We also propose an effective power control scheme, where a power increase command is sent to all users before a new high data rate packet is transmitted. Simulation results show that joint utilization of the proposed two methods is effective to keep signal quality good for all users.
