An analytical approach is developed to evaluate the performance of a hybrid base station (BS) location model which considers the location regularity of macro BSs and topological randomness of small BSs, where the coverage probability and spectral efficiency are derived and verified by simulation. When both tiers have the same BS intensity, the tier of tessellated macro BSs achieves a 50% advantage...
In this paper, we analyze the performance of a dense small cell network with multi-antenna Base Station (BS)s employing spatial Poisson Point Process (PPP) model. In this model, the BSs and User Equipment (UE)s are distributed as two independent PPPs which are well appropriate for upcoming small cells in the next generation of wireless systems. We consider the scenario in which the small cell BSs...
In this paper, we present a dynamic fractional frequency reuse (D-FFR) scheme for OFDMA based cellular networks. The proposed approach is extended from the so-called strict FFR architecture by allowing a fraction of the cell-edge frequencies to be shared by the edge users of the neighboring cells. This sub-band sharing flexibility not only alleviates the spectral deficiency of the strict FFR against...
