What is ICIC (inter-cell interference coordination)?

Inter-cell interference coordination methods show a solution by applying limitations to the radio resource management (RRM) block, and further developing favorable channel conditions across subsets of clients that are affected by the interference. Inter-Cell Interference Coordination is presented in 3GPP Release-8 specifications. It is used to mitigate interference on traffic channels in particular. ICIC is inherently a multi-cell RRM function that necessitates to consider data from different cells.
