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
