Performance Evaluation of Strict Fractional Frequency Reuse and Frequency Reuse Factor-3 in 5G Networks

Abstract

The need for high speed data traffic on mobile devices has risen because of the permeating use of gadgets, such as mobile smart phones, notepads and tablets that are constantly running on data. In order to meet these requirements, mobile network providers must set up both tiny cells, high-capacity and very dense, base stations (BSs). This is to cover not only a vast area but also including hotspots with quick, adaptable, and robust supply. The overall spectral efficiency of 5G networks must be improved, and the operations and deployment costs must be decreased. This paper evaluates and compares the performance of Strict Fractional Frequency Reuse (FFR) and Frequency Reuse Factor-3 (FRF-3) according to the cell throughput and cell spectral efficiency with the theoretical peak throughput and peak spectral efficiency as specified in NR 3GPP specifications. The results from the simulation revealed that the FFR performs much better than the FRF-3, however, it is still not efficient in relation to the peak values.
