Abstract

Scheduling in HSDPA based UMTS networks - is among the most interesting issues in resource management and optimization of enhanced 3G networks. Mathematical expressions of HSDPA cell capacity either in terms of number of mobiles or throughput per user - are given in this paper for different modeled scheduling techniques such as the classical "Fair Time" and "Fair Throughput" and both the newly introduced multiple services scheduling techniques: "Prioritized Differentiated Services Scheduling" and "Weighted Round Robin" for which optimal services weights are provided. These expressions are generalized as a function of the traffic area density in a uniformly distributed traffic. Impact of multi-user diversity on capacity is also mathematically modelled by the intermediate of service activity factor.
