“…In [5], FRP has been proposed for the OFDMA based IEEE 802.16m and 3GPP-LTE systems as ICIC technique. In addition, through using different cluster sizes, FRP has been suggested in [6] to be a very useful technique to achieve high spectrum efficiency in cellular systems.…”

BSTRACTThis paper focuses on evaluating the performance of a cellular network using power control based frequency reuse partitioning (FRP) in downlink (DL). In our work, in order to have the realistic environment, the spectral efficiency of the system is evaluated through traffic analysis, which most of the previous works did not consider.To further decrease the cell edge user's outage, the concept of power ratio is introduced and applied to the DL FRP based cellular network. In considering network topology, we first divide the cell coverage area into two regions, the inner and outer regions. We then allocate different sub-bands in the inner and outer regions of each cell. In the analysis, for each zone ratio, the performance of FRP system is evaluated for the given number of power ratios. We consider performance metrics such as call blocking probability, channel utilization, outage probability and effective throughput. The simulation results show that there is a significant improvement in the outage experienced by outer UEs with power control scheme compared to that with no power control scheme and an increase in overall system throughput.

“…It is a form of static planning and aims at increasing the capacity by using different frequency reuse factors for certain mobile terminals. It was first introduced by Halpern in 1983 [10] under the name of reuse partitioning and re-invented in the late 1990ies as intelligent underlay-overlay [11], [12], [13], [14]. Within the activities of the WiMAX forum and 3GPP LTE standardization, it is known as Fractional Frequency Reuse (FFR) (e.g., [15]).…”

Abstract-The currently emerging 802.16e (WiMAX) and 3GPP Long Term Evolution (LTE) cellular systems are based on Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA suffers from heavy inter-cell interference if neighboring base stations use the same frequency range. One approach to solve this issue is the application of beamforming antennas in combination with interference coordination (IFCO) mechanisms between base stations. In this paper, we trace the problem of IFCO back to the graph coloring problem and investigate the achievable resource utilization of the interference coordinated system. We develop a heuristic that allows the combination of arbitrary scheduling algorithms with the IFCO mechanism. This allows an efficient utilization of the radio system's frequency resources while still obeying scheduling constraints, such as Quality of Service requirements. Finally, we study the tradeoff between fairness and the total system throughput.

Abstract-OFDMA-based IEEE802.16 implements Adaptive Modulation and Coding (AMC) which results in a different bit rate for each user depending on its position in the cell as well as the radio condition it experiences; users away from the base station experience lower throughput. We hence propose in this paper a new QoS solution that compensates the degradation in modulation by a higher number of sub-carriers so as to maintain the bit rate of streaming flows at a constant level throughout the whole coverage area. This proposal is modeled analytically in a dynamic user configuration, where users of both types, streaming and elastic, remain in the system for a finite duration. And this in multi-cell environment and for different frequency reuse schemes.
