A Self-Adaptive, Utility-based Scheduling for Wireless Cellular Networks
Mobile and Wireless Communications Summit, 2007. 16th IST; 08/2007
Design of efficient scheduling algorithms has an important impact on performance of wireless mobile networks. 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 Ut... [more] Design of efficient scheduling algorithms has an important impact on performance of wireless mobile networks. 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.

Inter-cell Interference Management by Dynamic Channel Allocation, Scheduling and Smart Antennas
Mobile and Wireless Communications Summit, 2007. 16th IST; 08/2007

[more] An impact of dynamic channel allocation, opportunistic scheduling and smart antennas on inter-cell interference, and consequently on system performance is studied in this paper. It is shown that from the receiver point of view the most effective inter-cell interference reduction method is the opportunistic scheduling, followed by smart antennas, and dynamic channel allocation. Furthermore, interesting trade-offs that can be made by combining these techniques are observed as well.
