Abstract
Heterogeneous cellular networks (HetNets) is key technology in 5G used to tackle the ever increasing demand of data rate. The most critical problem of HetNet is interference. In this paper, we utilize the coordinated beamforming technique to mitigate the interference problem. We also suggest that reference signal receive power (RSRP) based cell association scheme has limitation when applied to multi-tier cellular networks. Therefore, we propose a new cell selection approach for HetNets, which is based on average channel gain. Simulation results of our designed beamformers show improvement over other schemes in terms of achievable information rates per cell.
