This research is concerned with techniques for supporting integrated services over a wireless cellular network. A fundamental problem is how to allocate radio resources to different users to optimize an overall network objective criterion while satisfying Quality of Service constraints. Wireless networks based on Direct-Sequence (DS)-Code-Division Multiple Access (CDMA) networks are considered, since DS-CDMA is a strong contender for next generation cellular systems. Radio ``resources'' in a DS-CDMA network include transmitted powers, processing gains, and number of assigned codes. The focus of this research is on Dynamic Resource Allocation (DRA) in the presence of time-varying user requests. The goals are to (1) Develop techniques for DRA given multiple traffic flows with different Quality of Service (QoS) requirements, and (2) Characterize performance/complexity tradeoffs associated with these techniques given simple traffic and propagation models.
