Summary With the advancement of mobile networks, the demand for increased throughput is continuously rising. Throughput is the amount of error‐free bits transmitted in a given period of time. Heterogeneous networks (HetNet) are widely accepted to enhance the throughput as they do have low pathloss among the others. HetNet deploys another cell under the coverage area of the macro cell. The HetNet offloads the macro cell that avoids congestion and enhances the coverage of the network. In HetNet, however, intercell interference is a major challenge that adversely degrades the throughput. In this paper, coordinated multipoint transmission (CoMP) along with a coordinated beamforming (CBF) is integrated to mitigate the intercell interference (ICI). In general, the results have shown that the proposed technique has resulted into significant interference reduction and hence improved throughput and spectral efficiency.
