Abstract :The heterogeneous network (HetNets) emerge as one of the most auspicious improvements toward realizing the objective specifications of Long Term Evolution-Advanced (LTE-A) networks. Though, similar all other wireless networks, HetNet also yield from the interference problems, i.e., the co-tier and cross-tier interferences. Regarding proper functionality and efficiency of the HetNets, the avoidance and management of the said interferences are very crucial. In this study, a power control algorithm is suggested to decrease the interferences disadvantages in the HetNets. To calculate the signal power, the SINR (Signal to Interference and Noise Ratio) and RSRP (Reference Signal Received Power) are used for downlink and uplink respectively. The selection decision is taken by signal strength information. The UE (User Equipment) is switched accordingly. A simulation is used to investigate and find out the nearest cell to UE in a HetNet.Keywords : LTE-A, HetNets, HeNB, user equipment, RSRP, SINR
