Summary

3GPP introduces inter-cell interference coordination (ICIC) mechanisms such as frequency domain ICIC in Releases 8/9, CA-based ICIC in Release 10 and time domain ICIC in Release 10 for management of such inter-cell interference in LTE. This chapter describes network deployment scenarios for which inter-cell interference is applicable and examines the ICIC mechanisms supported in the LTE. A homogeneous network has similar characteristics in terms of the architectural requirements, service coverage, and so on. CA-based ICIC is applicable when eNB controls both aggressor and victim cells. The concept of time domain ICIC is that the subframes are partitioned into two sets so that the aggressor cell and the victim cell use different sets of subframes. The aggressor cell mutes certain subframes by restraining any scheduling on those subframes to suppress generating interference to the victim cell.
