Carleton University - School of Computer Science Undergraduate Honours Project Fall 2010 Resource Allocation Analysis of OFDMA Femtocells Using Fractional Frequency Reuse Temirlan Kumargazhin 
ABSTRACT Femtocells are small size, low-power home base stations that are being deployed for better coverage and higher data rates. But benefits are not without challenges: the problem of interference between femto and macrocells has to be solved in advance. Possible cases of frequency allocation in the OFDMA systems using Fractional Frequency Reuse (FFR) are proposed and analyzed in this paper. In the proposed cases the macro users are pre-allocated with the FFR, and the sub-bands that can be allocated for the femtocells are investigated. Femtocell resource allocation guidelines are given with the assumption that the priority is on the macro users' performance. The simulation tool is developed in order to estimate the perfromance of macro and femto users to show the enhancement of throughputs. |
