Non-unanimous power inter-cell interference coordination in heterogeneous networks

Abstract

Heterogeneous Networks (HetNet), particularly Femto cells, were introduced to meet the exigent need for higher network capacity. Although Femto cells increased the network capacity, they increased the interference to the Macro Indoor users.In order to avoid the high decrease in cell edge throughput different interference mitigation techniques were introduced like Inter-Cell Interference Coordination and Power Control techniques. In this paper, Non- Unanimous Power Inter-cell Interference Coordination (NUP-ICIC), and Non Unanimous Power Control with Constraint (NUP-C) algorithms are proposed. The schemes can achieve high spectral efficiency with an increase the cell-edge and with high power efficiency. © 2012 IEEE.
