Abstract

1xEV-DV has been proposed as one of the standards of the next MultimediaWire- less Generation (MWG) systems, which adopts new techniques to enhance wireless data Quality of Service (QoS). Despite the recent research efforts in mapping QoS pa- rameters cross the different layers, there is still no cross layer QoS design that focuses in providing QoS assurances in the 1xEV-DV. Moreover, many possible combinations of resource parameters have been specified in the current standard. However, there are no specifications about the dynamic resource allocation. In this thesis, a suite of Cross Layer Multiuser Diversity Modules are proposed. These modules include a pri- ority admission module, a dynamic resource allocation module, a resource scheduling module, and a Fuzzy QoS manager. All these modules are closely integrated with the recently developed 1xEV-DV technologies with a concentration on the dynamic resource allocation module that will utilize the effective capacity concept. This mod- ule will enable dynamic resource allocation of the optimal combination of resource parameters such as the number of Walsh codes, the number of time slots, and the modulation scheme. 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. Performance evaluation of the proposed design that complies with the 1xEV-DV Evaluation Methodology is also presented.
