When a UE moves away the serving eNodeB (eNB) and becomes closer to the neighbouring eNB (see fig.1), the strength of desired received signal decreases and the ICI increases.The impact of ICI in LTE downlink can be analysed according to the received signal to interference and noise ratio (SINR) of UEm on resource block n (RBn) as
