Due to the non-stationary wireless links and the rapid increase of new types of applications that require different levels of QoS parameters, the support for better QoS for the emerging 3GPP2 multimedia wireless applications becomes strongly needed. These parameters include: priority, delay, data loss, and data rate. Many possible combinations of system parameters have been specified in the current 1xEV-DV standard. In this paper, we first present an overview of the latest 3GPP2 1xEV-DV standard focusing on its features and newly introduced physical channels. Then, we propose a new dynamic resource allocation scheme that is closely integrated with the recently developed 1xEV-DV technologies. This scheme will utilize the effective capacity concept to enable dynamic resource allocation of the optimal combination of system parameters. It will allocate resources not only based on the channel condition estimate but also according to the type of services requested in order to achieve promised system overall throughput gain and to meet the QoS requirement imposed by the different user's applications.
