The previously proposed scheduling algorithms like Best CQI and Proportional Fair have good performance, but only for certain load and services types. Within this work, we propose a novel Utility based Scheduling algorithm, which is fully adaptive to service and load conditions and includes some well known scheduling algorithms as special cases. We show by using dynamic system level simulations that the algorithm provides same or substantially better performance than these scheduling algorithms, with low signalization and computation overhead.

In this work we analyze, analytically and by means of dynamical system level simulations, the impact of dynamic channel allocation (DCA), power control (PC) and smart antennas (SA) on interference reduction and consequently on system performance. Our results show that the most effective interference reduction method is SA, followed by PC and finally DCA. Furthermore, we show fundamental trade-offs concerning combined usage of these techniques.

The algorithms are shown to have good performance, but only under certain conditions (load and interference). Within this work we propose and investigate a new Cost Function based distributive DCA algorithm. It will be shown that the algorithm is fully adaptable and performing optimally over the whole range of operation of cellular wireless mobile communication networks. The algorithm includes some well known DCA algorithms like Random channel allocation, Autonomous Reuse Partitioning and Minimum interference as special cases. We also show that in the case of non-real time packet data services Cost Function based DCA achieves for some loads better performance than any of the investigated DCA algorithms Index Terms-DCA, Cost Function, ARP, measurement based RRM algorithms, Power Control, Smart Antenna.
