Abstract :The heterogeneous network insert ignore into journalissuearticles values(HetNets); emerge as one of the most auspicious improvements toward realizing the objective specifications of Long Term Evolution-Advanced insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Signal to Interference and Noise Ratio); and RSRP insert ignore into journalissuearticles values(Reference Signal Received Power); are used for downlink and uplink respectively. The selection decision is taken by signal strength information. The UE insert ignore into journalissuearticles values(User Equipment); is switched accordingly. A simulation is used to investigate and find out the nearest cell to UE in a HetNet.
