Performance Evaluation of Sectorized Fractional Frequency Reuse Techniques Using Novel Metric

چکیده
LTE Femtocells are designed to increase capacity and coverage especially for the indoor and cell-edge mobile users. Typically, they are deployed to offload t he macrocell users. However, due to co-location of femtocells in macrocell coverage, the co-tier and cross-tier interferences are high. Fractional Frequency Reuse mechanism (FFR) is one of the most effective femtocell interference avoidance techniques. In this paper, we propose a new metric to determine optimal inner region radius and frequency allocation which optimizes the total cell throughput and serves as many number of users in the network. The new metric is applied to sectorized FFR methods and their performance is compared with increasing volume of femtocell deployment.

A capacity degradation model under interferences for sectorized cellular networks with fractional frequency reuse
This paper presents a capacity degradation model under interferences for sectorized cellular networks with fractional frequency reuse. In a sectorized fractional frequency reuse network, allocated bandwidth consists of a number of frequency partitions. To avoid intra-cell interferences, each frequency partition is then assigned to two different groups, the super group (Sup-G) and the regular gr...
متن کاملA Multi-Agent Neural Network for Dynamic Frequency Reuse in LTE Networks
Fractional Frequency Reuse techniques can be employed to address interference in mobile networks, improving throughput for edge users. There is a tradeoff between the coverage and overall throughput achievable, as interference avoidance techniques lead to a loss in a cell’s overall throughput, with spectrum efficiency decreasing with the fencing off of orthogonal resources. In this paper we pro...
متن کاملA Fairness-based Performance Evaluation of Fractional Frequency Reuse in LTE
This paper evaluates the downlink performance of Fractional Frequency Reuse (FFR) in Long Term Evolution (LTE) networks employing a metric combining throughput and fairness, which we argue better depicts the effects of FFR. This is as opposed to previous work, which focused on capacitybased metrics, evaluating only the mean, peak (95%), and edge (5%) points of the capacity distribution. We eval...

Long Term Evolution (LTE) networks offer high capacity and are specified and designed to accommodate small, high performance, power-efficient end-user devices. One limiting factor that influences LTE performance is the interference from neighbouring cells, the so called Inter-Cell Interference (ICI). The investigation of ICI mitigation techniques has become a key focus area in achieving dense s...

We present a novel frequency partitioning technique of fractional frequency reuse (FFR) that reduces the effect of co-channel interference and increases the capacity of OFDM systems. The usable sub-channel sets are classified into the common sub-channel sets for all cells and the dedicated sub-channel sets for specific cell types in FFR. The proposed fractional frequency reuse with ordering sch...
