Abstract

Packet-switching communication is gaining an ever increasing relevance for wireless networks. On one hand, releasing radio resources to single communication units, i.e. the packets, is much more efficient than releasing resources to entire connection; on the other hand, IP is becoming the predominant technology in the backbone network for integration and transport of heterogeneous multimedia and data traffic. Two important radio resource optimization problem have to be considered, within this framework, for the design of MAC and RRM functionalities in a wireless packet network. The first problem is to look for the best way (as a tradeoff between capacity and complexity) to dynamically assign radio resources to a set of users having packets to transmit. The second problem is to look for the best way (as a tradeoff among capacity, user satisfaction, fairness and complexity) to schedule packet transmission in time over the available radio resources for a set of users with one or more packet traffic sources with possible QoS constraint.
