Summary form only given. CDMA2000 1xEV-DV has been proposed as one of the global standards of 3G networks, which adopts TDM/CDM and adaptive modulation and coding (AMC) techniques to enhance the data rate up to 3.1 Mbps. Even though the current CDMA 2000 1xEV-DV standard specifies all combinations of the system parameters such as encoder packet size, modulation scheme, the number of time slots per sub-packet, and modulation and coding schemes. However, it is still unknown how to dynamically change physical layer parameters to support the upper layer quality of service (QoS). Given a certain channel quality, to meet the committed quality of services (QoS) in terms of throughput, delay and delay violation probability, we need to select the optimal combination of system parameters. In this paper, we develop a dynamic resource scheduling scheme for supporting delay-bounded multimedia services in CDMA2000 1xEV-DV networks. Simulation results show that the proposed dynamic resource scheduling scheme significantly improves the delay and throughput performance for all types of data traffic with various QoS requirements.
