| Summary: | Interference Management (1M) is one of the major
challenges of next generation wireless communication. Fractional
Frequency Reuse (FFR) has been acknowledged as an efficient
1M technique, which offers significant capacity enhancement and
improve cell edge coverage with low complexity. In literature,
FFR has been analyzed mostly with cellular networks described
by Hexagon Grid Model, which is neither tractable nor scalable
to the dense deployment of next generation wireless networks.
Moreover, the perfect geometry based grid model tends to
overestimate the system performance and not able to reflect the
reality. In this paper, we use the stochastic geometry approach,
FFR is analyzed with cellular network modeled by homogeneous
Poisson Point Process (PPP). A dynamic frequency allocation
scheme is proposed which take into account the randomness
of the cell coverage area describe by Voronoi tessellation. It is
shown that the proposed scheme outperforms the traditional fixed
frequency allocation schemes in terms of per user capacity and
capacity density. |
