Uplink capacity analysis of OFDMA based cellular networks with reuse-1
Abstract--OFDMA based cellular radio networks aim to operate as close as possible to frequency reuse distance of one, where the whole spectrum would be available in every cell. Modern systems are able to adjust parameters such as transmission power, modulation, and coding separately for each frequency sub-channel on a very short time scale. This way Fractional Frequency Reuse (FFR) can be applied, allowing to operate reuse1 in the center of cells and reuse greater one at cell edges. This paper presents a novel method to analyze the Carrier to Interference Ratio (CIR) distribution and uplink capacity of a cell, from which spectral efficiency of a cellular radio network using FFR is derived. The results presented apply for OFDMA cellular networks operated in IMT-Advanced evaluation scenarios.
