The increasing energy consumption driven by striking growths in the number of users and data usage turns out the focal point for mobile operators in fulfilling requirements on cost reduction and environmental impact targets. Deployment of heterogeneous networks (HetNet) using coordination between the traditional macro cell and lower power nodes (such as picocell, relay so on) is desired to reduce the total energy consumption of cellular radio networks. This paper investigates the cell’s energy efficiency of single frequency HetNet coordination multi-point (CoMP) networks. Applying the single frequency HetNet CoMP as a baseline network we further extend our work to different frequency planning networks such as fractional frequency reuse (FFR). The simulation results suggest that introducing HetNet CoMP can achieve improved overall cell energy efficiency (EE) whereas HetNet CoMP using FFR increase cell-edge EE which evolves a trade-off for the operator.
