Research on inter-cell interference technologies in LTE system
Abstract:In the LTE system, inter-cell interference becomes main interference source of LTE system because of Orthogonal Frequency Division Multiplexing used in the physical layer. How to reduce the inter-cell interference is one of hot topics in LTE system research. In this paper, several classic Inter-cell Interference technologies are introduced. Besides, it analysis of their strengths and weaknesses, as well as existing problems.
Keywords: LTE inter-cell interference coordination SFR
