A SURVEY OF INTERFERENCE MITIGATION TECHNIQUES IN FEMTO-MACRO HETEREOGENEOUS NETWORK

Abstract

Heterogeneous Network (HetNet) is a mixed of small based station such as femto, pico, and
micro cells within an existing coverage area of macro cell. It has been proposed by the 3rd
Generation Partnership Project (3GPP) to provide a solution for high demand of data by
customers. However, one major challenge of HetNet is interference which could lead to low
data rate if not mitigated. In this paper, a review of existing interference mitigation
techniques in Long Term Evolution release 10 (LTE rel. 10) is presented and concluded by
proposing a new technique to mitigate interference in a femto-macro HetNet.
