Introduction of QoS (quality of service) control is demanded in wireless networks. The reserved MAC protocol with QoS scheduling is necessary, because mobile terminals access at random in the uplink (mobile terminal to base station). In this paper, we defined QoS as allowable delay time in uplink, and proposed a new QoS control scheme for CDMA. The proposed scheme is composed of dynamic queuing control and dynamic bandwidth allocation control. Simulation results show that the proposed system guarantees delay time and the performance is better than priority queuing
