A Survey on Inter-Cell Interference Co-ordination Techniques of LTE Networks

-The Long term evolution (LTE) is a latest technology standardized by 3 rd generation partnership project (3GPP) to fulfill the growing demands of the users like high data rates in downlink and uplink, low cost, high spectral efficiency etc. Due to the growing demand for high data rate there is need to focus on frequency reuse i.e. reuse-1 so that we can get complete spectrum with in a cell. But the major problem is co-channel interference which increases due to the co-channel adjacent cells. So in frequency planning some co-ordination strategies should be considered to allocate the frequency bands in such a way that minimizes the inter-cell interference. There are different inter-cell interference coordination techniques for minimizing the interference like Frequency Reuse Distance scheme, Frequency reuse based schemes: Traditional/ Conventional Schemes, FFR and Dynamic channel allocation etc. This article represents an overview on LTE architecture and the inter-cell interference coordination techniques (ICIC).
