Abstract:

LTE systems applied more flexible frequency re-use strategies. All cells in LTE systems are possible to use the whole spectrum resource,which makes inter-cell interference unavoidable. In this paper we review the major 3GPP proposals and academic research of inter-cell interference mitigation,mainly in two categories of interference coordination and interference cancellation.New techniques for inter-cell interference mitigation in LTE evolutions are also investigated.

Key words: inter-cell interference, interference mitigation, cooperative scheduling
