Outline of Final Research Achievements

In view of the next generation wireless communication systems, we have proposed distributed resource allocation methods for a macrocell/femtocell Heterogeneous Network whereby each femtocell may be deployed by each user. In particular, our developed solutions take advantage of the broadcast nature of wireless signals for obtaining local channel state information. This enables to jointly optimize the different system performance metrics such as cell throughput and user fairness in both macrocell and femtocells, while minimizing the amount of required signalling overhead. The effectiveness of the proposed schemes against conventional solutions was confirmed through computer simulations.
