Résumé:
This paper discusses the resource allocation problem
in an uplink multi-cell OFDMA system. The classical LTE model
considers two areas in the cell: the cell center and the cell border
and divides the resources in four sets. The users in the cells center
zones use the same subset of subcarriers whereas the users of
the border zones use the remaining resources with a Fractional
Frequency Reuse (FFR) equal to 3. Considering the same cell
zones, we present in this work a different FFR model and prove
with a theoretical analysis that the system throughput can be
improved. The resource allocation is then performed considering
the Weighted Proportional Fair (WPF) algorithm. Simulation
results illustrate the performance improvements of the proposed
solution in comparison to the classical model. The fairness for
the different models is also studied and compared.
