Femto-Cell Resource Partitioning

Abstract: This paper studies the impact of a femto-cell underlay deployment that shares radio frequency resources with urban macro-cells. Femto-cells promise substantial gains in spectral efficiency due to an enhanced reuse of radio resources. However, owing to their random and uncoordinated deployment, they potentially cause destructive interference to macro-cells and viceversa. In order to maintain reliable service of macro-cells, it is most important to mitigate destructive femto to macro-cell interference. In the do… Show more

“…Figures 7 and 6(a) reveal a very important problem that is expected to be encountered in systems with femto-cell deployment: extremely severe downlink interference originating from the HeNB, which renders the vulnerable macro UE incapable of achieving a useful downlink SINR. In Reference [22], the authors propose a method of mitigating this interference.…”

“…In order to cancel interference in heterogeneous networks, different interference mitigation techniques have been proposed [12,13]. One of the recent and effective approaches to deal with interference issues in heterogeneous networks is the interference alignment (IA) technique [14].…”

“…In this context, the wireless networks require more careful and dynamic planning and if these two systems are not carefully designed then it will cause harmful interference, hence degrading the performance of both macro-cell and small-cell systems [14]. In order to deal with interference issues in heterogeneous networks different interference management techniques have been proposed [15]- [17]. Also multiple antenna techniques in combination with CR have been considered in some publications [18], [19].…”
