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.
